Mondeo diesel starting - or not... - Alan Clark
Okay - when cold, my poor old 1994 L reg 1.8TD Mondeo hatch is a bu***r to get going. Turn the key, pre-heating on for prescribed time, crank, fires for 2 - 3 seconds and stops. Much cranking and pumping of throttle and it eventually fires. Once going, it is wonderful. Starting from warm to hot is fine. This all became apparent last winter but 'cured' itself until approx a week ago. Performance is pretty good for a diesel with over 160,000 miles and averaging 50 mpg so I would discount fuel starvation or air in the system; doesn't hesitate, pulls well enough, air filter is 3 months old. I do use Safeway fuel but have, for the last 2 months, been using Millers Diesel Power Plus (no significant obvious gains or losses there). I did have a fuel pump failure about 100,000 miles ago. Unit was replaced. That failure was similar ie engine stalled as I selected first but would not start again. Any clues / pointers will be very gratefully received and I offer my thanks in advance.
Re: Mondeo diesel starting - or not... - Simon
Have you checked the glow plugs?
Re: Mondeo diesel starting - or not... - David W
Alan,

Two things.....

We have to know about the glowplugs.

The fuel filter housing/primer fails on these vehicles giving rise to start problems.

I lied, here's a third. Folks often underestimate the importance of a fast starter motor to spin a diesel. Many Ford 1.8TD starters are sluggish after 100K.

Re: Mondeo diesel starting - or not... - Alan Clark
Oops! Glow plugs are about 60k old. The ones I changed about 100k didn't seem too bad (going by the Haynes book pics...). Might be time to change them I suppose. Cranking speed seems okay...puts out oil pressure light and speed on tacho is almost to first mark, which hasn't noticably deteriorated in the 110 k that I have owned it. So it's glow plugs after pay day and a job for the weekend! When I suffered the last failure as mentioned in the opening gambit, Mister RAC found there was no pressure build up on the primer. Maybe that was the pump they changed (hope so...the injector pump looks like a dog to change!). Thanks!
Re: Mondeo diesel starting - or not... - Alan Clark
One more thing which has come to mind...I tried the hand primer one morning and after a single stroke, there was a good resistance thus indicating presure there. Further to the glow plugs...why does it run for 2 - 3 seconds then die...? Yours confused now...think I will stick to aeroplane engines...they are easy-peasy!!
Re: Mondeo diesel starting - or not... - Mahatma Coate
Do you leave it parked on the flat. One of our wretched VW's cuts out after 2-3 seconds and the dealer says it's because it gets parked facing slightly uphill. I think this was once a problem with XUD engined Citroens - or was that downhill?

Always seemed like a cop out to me.
Re: Mondeo diesel starting - or not... - Alan Clark
It's flatter than a flat thing! Probably one of the few advantages to living in Skegness!!! Thanks anyway - sure does sound like a cop out too.
Re: Mondeo diesel starting - or not... - vansboy
Not sure if it's same as Escort, but is the heater plug relay working?
Switch ignition on, wait for dash display light to go out,listen for relay 'click', THEN turn engine over.Get this a lot on old vans.
Running, then cutting out,sounds like air in system,probably at pump intake.
Nothing that money won't put right!!

Re: Mondeo diesel starting - or not... - Eddie
can you recall what the fuel pump replacement cost, I am facing that right now. thanks
Re: Mondeo diesel starting - or not... - Alan Clark
Sorry...it was done under warranty so I have no idea. Probably a couple of noughts at the end no doubt...
Re: Mondeo diesel starting - or not... - steve paterson
Alan,
A quick way to check the glow plugs and associated electrics is to use an ammeter. On the small Fords I've worked on the plugs draw about 60amps when cold. As they warm up this drops fairly quickly to about 40amps. After about 8 - 10 secs you should hear a relay click and the current draw should drop to a couple of amps. As each plug draws about 15amps when cold any variation in the given figures probably means a duff plug(s). Check the plug spec. though.
Must say, as has been mentioned, it sounds more like an air ingress problem, and the filter head / primer is a good place to start looking.
Re: Mondeo diesel starting - or not... - terryb
New diesel pump on a Citroen BX a couple of years back was 900 quid. Cheaper to recondition, but this one was beyond that.

Hope Ford comes in cheaper for your sake!
Re: Mondeo diesel starting - or not... - Andy T
Is the filter head the Bosch type with a slanted top, and primer button in the middle of the top? If so, the diaphram on this type dozes (not as in sleeping!!), letting air in, and so lets the fuel from that point run back to the tank.
This means the engine may start as normal for a few seconds, and then cut out.
Re: Mondeo diesel starting - or not... - Alan Clark
By the looks of it, it's a CAV type. It is very symptomatic of fuel draining away though...enough to run for a moment then having to draw more fuel up and in to burn. Could the CAV type also 'doze'? Must say, I haven't heard of this before, simply puncturing, but I can see how it could be possible...thanks...will try it at the weekend! Got to beat the £900 mentioned earlier...jeez, it's more than the car is worth...even with 4 new shocks!
Re: Mondeo diesel starting - or not... - Andy T
A way to prove the air theory is to temporarily replace the fuel pipe from the filter to the pump with a piece of clear fuel tubing.
Then, when the engine is running, check for air bubbles in the line. The odd little one should be fine, but initally after priming, it may take time to clear of air.

Of course, with a diesel the best test is from a cold start (as you know!).

Other options I could think of are the various sealing washers/o-rings on the filter assembly, (has it recently been worked at?) or possibly a porous hose.

I realise that its easier to theorise than to locate the problem, but if the filter has not been touched, then the clear fuel hose is probably a good/inexpensive starting point. To my mind, the fact that it starts and runs proves that the glow plugs are doing their job.
As an outside bet, have a test lamp connected to the stop solenoid on the pump to disprove an unlikely loss of volts.

I wish you success.

Well fancy that! New set of glow plugs and away the old bus went. A very big thank you to all who contributed suggestions to my dilemma. Still do not understand why it fired for a couple of seconds. However, it's all good again. Maybe a new fuel filter helped too. Again, thanks!

Mondeo diesel starting - or not... - SteveH
Hi ,
I know this thread is getting on a bit but I've recently bought a 1.8 TD Mondeo on an 'L' plate. Do you know the correct procedure for starting. When I turn on the ignition the dash lamp for glowplugs lights for 2-3 secs max. Turning the key further (with foot flat to floor or no throttle at all)fails to start. If I reset the ignition and try again, the glowplug light stays on for 1 sec, then if I crank it for long enough it splutters into life (seems to run fine otherwise).seems very hard on the battery/starter motor.
Any ideas/what am I doing wrong?
Mondeo diesel starting - or not... - Mr Smegma
Almost definately dead glowplugs.

Mondeo diesel starting - or not... - M.M
Steve,

How does it start later in the day when it has cooled right down but had a run earlier?

David W
Mondeo diesel starting - or not... - Dave_TD
I'm lead to believe that when the glowplug light goes out (after 3-5sec) this doesn't mean the plugs have switched off, just that they are warm enough to permit starting.
When you start the engine, they should remain on for a while, up to 15sec after it catches, before the compressed diesel/air mixture is sufficiently hot to guarantee good running.
This is something to do with the emissions equipment fitted to Mondeos, a single catalyst in the downpipe roughly under the soles of your feet!
You can tell if the glowplugs do stay on after it has fired up by keeping the door open and watching the interior light - it should get brighter when the 'plugs cut out.

>>How does it start later in the day when it has cooled right down but had a run earlier?

It takes a fully warmed-through engine up to 36 hours to cool right down, depends on the ambient temperature in Skegness.


Hey Vansboy, *I've* seen you on the M1! ;-)

I ran 2 Maestro 700 diesel vans about 6 years back, H275HCT in white and H585BFT in blue. 350,000miles each before they dropped! We never used to change glowplugs, although on a cold morning you'd switch the ignition on, wait 15sec for the light to go out, wait another 15sec, then switch ignition off and repeat 4 or 5 times. THEN they started....

DW >>How does it start later in the day when it has cooled right down but had a run earlier?

Dtd >>It takes a fully warmed-through engine up to 36 hours to cool right down, depends on the ambient temperature in Skegness.

OK I'll put it another way.

Assuming the engine compressions are fine and the battery/starter condition are OK to produce a good cranking speed then the fault is most likely to be glowplugs or the diesel filter housing failing.

I was trying to help with the diagnosis between the two as a cold engine and a coolish one can both need some glowplug action. Hence poor glowplugs will be an issue when dead cold, not when up to full temperature but faulty plugs may still give poor starting when the thing has been standing for a while.

What often confirms the filter housing as at fault is the thing being a pig to start first thing but then it is fine all day, even if left for a bit...then a pig the next morning.

Of course just to replace the glowplugs and see what happens is the best option for the DIYer, not a favourite for customers though if you charge them for slinging in a set and it makes no difference.

I think it's the diaphragm inside which perishes, since replacement of rubber seals made no difference on mine. I got one from a scrappy for a fiver but it was just as bad as the old one. Tried taking old one apart to investigate but in the end gave up - they are sort of "sealed" with metal clips. Paid £60 for a new one - seemed expensive to me but was same from Ford and Cit dealers and independent bloke I went to
Mondeo diesel starting - or not... - M.M
Steve,

Phil is right.

Hardly worth messing round at the breakers to find one that could be u/s on fitting or fail in another month. Their prices are very variable, I've been asked betwen £20 and £80 for the same part (ABS ECU) from the same car by two different members of staff in the yard.

£60 is about the price I would expect for this new. Given the annoyance of a slow starting diesel in the winter, and the fact that this replacement is likely to outlast the car, I think they are decent value.

Oddly enough I seem to hear of them failing more on Fords than Citroens.

Mondeo diesel starting - or not... - rogerb
Just a point of warning, from personal experience: do NOT try to economise by using h@lfords, or similar, replacement glowplugs.

I had a set pack up after 3k miles, leading to a much more expensive(£70!) starter relay being replaced unnecessarily, because "It CAN'T be the plugs, they are nearly new" ! !
Mondeo diesel starting - or not... - BrianW
You can aso test glowplugs by checking the resistance with a meter.
IIRC they should give about 5 ohms resistance. (Someone may like to verify this)
If you get infinity or zero they are dead.
Mondeo diesel starting - or not... - RichardW
Glow plugs fitted to XUD diesels (Cit/pug) pull around 12 amps each, so only measure 1 ohm resistance. I'd have thought others were similar.


Richard
Mondeo diesel starting - or not... - BrianW

You're probably right.
It was about four years ago when I checked this on the old set of plugs out of my 309, but even with a cheap meter it was possible to identify the good from the dud.
Mondeo diesel starting - or not... - SteveH
Thanks for all this chaps, very helpfull.
What brand of plugs are the best? I've been quoted £6.50 each locally for 'Direct' ones.
Seems to start fine after a run etc. local mechanic suggested jump leads to each plug (after removal) and the ensuing glow should be from tip to body rather than the other way round.
relay stays on for 8 secs (same as her Escort).
Cheers again
Steve
Mondeo diesel starting - or not... - PhilW
Tthat sounds v. cheap for glowplugs. I used cheap ones once and they only lasted about 6 months. The originals had lasted 100,000 miles! Go for the best - as fitted originally.

Are you sure that the resistance is not very temperature dependent? I=V/R will NOT apply to cold R measurement.

I had this problem on my wife's Peuoet 106 diesel. It is simple to test the glowplus with no equipment. Just remove them one by one and test each by earting each by a wire to the engine or battery earth lead, Then holding each with a gloved hand or a pair of pliers ask someone to switch on the engine when it is COLD> If the plug is OK, you will see it glow. Switch off and reinsert and try the next one.

WARNING : they get VERY hot - see precautions above.

I bought proper Peugeot ones: cheap alternatives are false economyimo: they have a very hard life.

Two had gone: I only replaced those: it is suggested you replace all 4 as a set but the orginal 2 left have now lasted 9 years..2 years after I replaced the first 2. (dealers say replace all 4 : I consider that equivalent to changing all eclectric bulbs when 1 breaks)

I have a Mondeo 1.8 TD which won't start in cold weather first thing in the morning using the key. However , I live at the top of a steep hill and it will bump start very easily indeed. So , I thought must be the battery. Bought a new Motorcraft battery. Still won't b***** well start with the key. Anybody got a remedy please ?
Mondeo diesel starting - or not... - SteveH
I've still got similar prob, one tip recently was to check the primer plunger travel before starting. If there is any movement it might indicate that air is getting into system overnight (probably thru the filter bowl unit itself (a known fault apparently). I am trying this myself on the weekend, weather permitting...
Escort TD loss of power - Spencer
My Escort TD used to pick up around 2.5 to 3 thousand revs but not since I changed my air and fuel filters. It just accelerates slowly and just picks up slightly within the 'Turbo rev range' It's as if I have lost turbo pressure. I changed both filters again after putting up with this for a while. This has made no difference.
I notice that with the fuel filter there are two large rubber seals, one smaller one (about size of 2 pence piece) and two smaller ones as well (about the size of five pence piece). I could not find a home for the two smallest rubber ring seals and assumed they were for different models. Is this my problem, is the filter losing pressure as a result. It is not leaking at all. Help please..

Escort TD loss of power - SteveH
Spence,
Looking at the Haynes, it does stress (with regard to the CAV filter housing)that you should check that you have replaced all the seals, even to the extent of using torch and mirror!
Typically Haynes tho, it doesnt show the seal arrangements for the various models and does not say how many are involved...
Escort TD loss of power - Spencer
If the fuel filter wasn?t sealed wouldn?t I have trouble starting and with stalling because it is sucking in air??
I've had a suggestion that my diesel pump might not be delivering enough pressure, but that was a garage who also admitted it would probably cost more than the cars worth to fix. Apparently the pump is around £950 without fitting!!!! One from a scrap yard (if you could find one) would be around £400 with no guaranty!! Also I?ve been told the hose off my turbo could be leaking because when you take off the air filter casings the ?decaying? hoses can split. This is a potentially engine wrecking problem as water can be sucked in through this split. Who knows. I might just change the car and be done with it. It?s N Reg and cost me £160 to get through the last M.O.T. (new rear drums, shoes, cylinder and fluid renew).

Escort TD loss of power - SteveH
It could be that its not drawing in air, but not working as it should inside the filter unit. It seems unlikely to be actual pump pressure if things were ok before you changed the filters.
Air hoses are a possibilty, but thats something you can check fairly easily...
if you have missed/damaged a seal on the fuel filter, you might not necessarily be getting full delivery to the pump, (enough to start and run, but starving when you accelerate).

Any diesel mechanics online?
All the best......
Escort TD loss of power - R.A
Hi SteveH and Spencer
On my Escort 1.8TD (L), I recently changed the Bosch (slanting) fuel pump with rubber primer on top, but then had substantial problems starting. My local friendly mechanic checked,replaced seals properly, and said that it was drawing in air from the two plastic pipes attached to pump, but fixed the problem.
The problem now, after several months, and in cold weather, the diesel engine wont start in mornings, and if it does, seems to stutter on two cylinders for a while.
I know what has been said here on this thread, but I have to ask this : in the mornings, when I check the rubber pump primer I can fully depress it until full (if you understand). Is this the way it should be after overnight standing, or should the rubber primer be full after overnight?
Thanks
R.A
Escort TD loss of power - SteveH
Hi R.A,
My recent experience on the CAV filter unit is that if I pump the primer (I get 2 full pump strokes) before I try to start it, it will fire up first time! (if its been standing overnight).

I checked it after an hour and could not depress the primer...
Which now convinces me that its the diaphram/filter mechanism (see above)which is knacked. It is actually mentioned at the top of this thread (some time ago), but I didnt read it properly..doh
Now the mission is to get a good one for less than 60 notes.....
Escort TD loss of power - Spencer
I've just checked my Escort TD and it has been standing for more than 7 hours. The primer could not be depressed at all and seemed to have healthy pressure. Try checking all fuel lines/seals and check for small leaks. Is your filter tight? Can you smell diesil when your driving with the heaters on? I had that and it was the 'deisel end stop leak'. It is a little rubber nipple on the last injector thingy from the pump side. There are rubber jumper pipes from injector to injector but obviously after the fourth injector there is that nipple. Look under the bonnet with the engine running (mind your long hair and/or ties) and rev it. Sometimes you can see spray from small pin hole sized leaks like what was in mine. I looked for this because I could smell diesel all the time but I could not see it when it was just ticking over. I was told to wait untill it was nearly dark and use a torch as any spray shows up better.

By the way I'm an electronic technician so I'm poo hot on electrics if any one needs some help.
Escort TD loss of power - R.A
Spencer
You were spot on with the Escort TD - I have faint whiff of diesel from the heaters when driving, and will check as you said. My initial problem of vehicle not starting after overnight sleep seems to be cured by my fitting 4 X Bosch Gloplugs (total £40). Now car starts frist time and drives like a dream (fingers crossed).Seems years ago only two plugs changed by the looks of carbon deposits on plugs, so the other two possibly original, especially the last one where it was damn difficult to get at(having to dismantle this that and the other to get at plug). The new fuel filter rubber primer seems to be almost full after overnight sleep, but car starts first time every time in cold weather hovering on zero (fingers now crossed).
Thanks.
R.A
Escort TD loss of power - Richard Thorp
Don't know if you've solved this yet.

I had this with my Mondeo TD.

The turbo was whistling it's head off, but no power at all.

It was like driving a bus, took ages to accelerate, and no
kick, when the turbo whistled.

I traced it to a split rubber pipe on the fuel pump !

if you look from the front of the car, at the side of the fuel
pump facing the radiator, there's a round unit about 2" dia.
(as I recall - this is from memory!)

There's a small rubber pipe on this which works its way
all the way round th front of the engine, under all the
air intake stuff and dissapears into the turbo, somewhere.

I believe that it's some kind of "pull-down" which increases
the fueling when the turbo reaches a certain pressure.

Not having any pipe that size, I just glued it up !! and Bingo,
it was like getting a new car !!
Escort TD loss of power - Spencer
Cheers for that. The symptoms you descride are identical to mine. The problem is there are many causes for the same symptoms. All of which I seem to have checked for except the one you describe. I shall check it in the morning.

thanks for your comments. One further thing which has come to mind is that ( and this might seem odd ) my heater control ( to direct the air to dashboard / footwell etc. ) has ceased to work . I am told that this works from a vacuum system and is not electronic as I'd thought. Could it be that a hose has come off do you think ? If so where will it be ??
Mondeo diesel starting - or not... - PhilW
Tony,
Sorry, can't help you on that!! Don't know Mondeos except that they use (used?) same fuel filter housing as some Citroens and they have proved prone to air leaks after a time. I also heard from a mechanic that they often have to replace them on Mondeos for that reason. They cost about £60 so it might be cheaper to test glowplugs first before spending that money.
No doubt plenty of other Mondeo owners will come to your aid!!

Hi,

I'm having trouble starting my Rover 115 now that the weather's turned cold so I've searched the net for ideas, one site suggested checking for air leakage into the fuel lines by applying grease to the joints. The idea being that grease will provide a temporary seal (at least until it dries out), using this method it is suggested that the fault could be traced by systematic greasing of the joints in the fuel line. For my car I think I'll check the glowplugs first.

Steve.
Mondeo diesel starting - or not... - the conductor
with your rover 115 same as cit ax or pug 106. rubber bellows type hand primer pump mounted by battery. the ball bearing inside causes the pump to allow air into system overnight thus will not start without loads of cranking or foot on throttle.
my ax14d did same pumped primer before starting would start first time if not loads of cranking. do not buy from citreon or rover as very expensive. avalible pattern made by company called lancer products. bout £10. this also applies to all pug and cit diesels as have same type of primer pump.
Mondeo diesel starting - or not... - Shigg
Thanks for the info, this could be next on the list. Today replaced glowplugs, one had completely gone (open circuit according to a multimeter) but all looked well worn. I tried priming the fuel system before starting first thing this morning but it didn't make any difference. We'll see how it likes it's new glowplugs. I think it's also time to look at recon injectors if the price is OK, the faulty plug had a very heavy carbon deposit (compared to the other plugs). I assume that this is a sign of a worn/faulty injector and probably why the glowplug failed.

I've just had a problem with an R reg diesel Mondeo.

One morning, it failed to start. There was some slight firing when the engine was turning over but not enough to keep the engine going under its own steam.

Changed the glo-plugs - no difference.
Bled the diesel line from the filter to the pump - no difference.

Thought it might be the fuel cut-off solenoid, but on this CAV
diesel pump, it seems to be hidden under a steel pressing.

Read about the fuel filter leak problems here, and having charged
the battery overnight, bled the diesel lines very carefully from the filter to the pump.

Tried starting the car three times, and it fired up on the third try.

I'll watch it carefully for the next few days, but I have a nasty feeling that it's the problem mentioned here, with air getting in through the filter housing, and it's 60 notes.

Thanks to all for providing the useful posts. I was on the verge of calling a garage out to deal with it.

re the 'Conductor' above,

have had new glow plugs fitted . It has done the trick ! It now starts instantly even when freezing cold. The heater switch does work off a vacuum system and the pipe had come off.

Mondeo diesel starting - or not... - rolf
Hi,
Maybe the problem is solved now.
Many times there is bad connection at the "feedthrough-joint"
where the glowplug cables are connected on the underside.
If it gets hot you have the indication of a bad crimping made
of the manufactorer of the "joint".
You can temporary repair it by a cutting plastic to get to
the crimp and redo the crimping.
When remounting the two sides cables of the joint,hold one side by a plier so it does not rotate inside the joints plastic.
The glowcurrent stays on a bit longer than the indicatorlamp
is indicating.After a while current is reduced and disappears
completely after about 1 minute.Perhaps less time if the system
has no bad connections along the line of the current connection.

Mondeo diesel starting - or not... - SimonG.
What type of pump is fitted, my p plate has a cav unit with an electric cold start device, this i presume allows more fuel through on cold starts, like the choke on a petrol engine, mine was rattling (ticking) but the power was there all the time so in a fit of temper (much playing about with car, filters check for air glow plugs etc) i cut one of the two wires, the car started instantly, but sounded like a wagon once warmed up, so in the interim i am fitting a switch to turn it back on once warm, will investigate further, there are only three possibilities now i believe, blocked fuel filter not allowing enough fuel through to keep valve open? temperature sensor to ecu telling it to open before it should or the ecu itself in which case my switch works any way - hope this helps simon.

SimonG, Which wire did you cut & where is the cold start device? My L reg Mondeo will not start when cold - tries but not enough fuel for her to catch fully - changed the filter head housing - cheaper from Motquip than the £60 mentioned above, renewed the copper washers on the housing, changed the glow plugs, changed the cut off solenoid on the pump, changed the filter & the hard to spot seal beneath & checked all the system for leaks. Only way to get it started when cold is to turn on the ig, loosen the fuel return banjo on top of the pump housing and bleed the system & away she goes. Will start from hot/warm and plenty of resistance in the morning on the primer plunger. Can only think it might be the cold start device. Any help gratefully received. Ian
