Hello, need some advice. my 1997 xantia turbo diesel decided to play up yesterday. I don't know if its the damp or what. typed in code just would not start. after switching engine off a number of times and re-typing code it started. Today not starting again, although this time the code is typed in and and the relay clicks on the starter turns but does not fired up.

If the engine is turning briskly and it's not firing; then checking the operation and condition of the glow-plugs would be a good place to start.

Agree with Screwloose, it's the time of year for PSA TD glowplugs - especially with most approaching 10 years old now - but a few simple checks first:
1. Does the red light go out and the green light come on on the keypad before you try to start?
2. If you pump the fuel primer (over the RH engine mount) before trying to start does this help?
3. When it starts does it do so in a big cloud of grey smoke?

Good evening guys,
I too have a stubborn Citroen Xantia 1996 TD.
The car needs to be started "on the key".....by this I mean I have to keep the key turned on for the best part of 20 seconds before the engine will fire and run....it runs very lumpy for a minute or so with bellows of white/grey smoke.
Once settled it runs fine with no smoke showing at all!!!
New Beru glow plugs were fitted last week and the problem is still there.......
anyone have any ideas???
|
That sounds like glow plugs too. If they are working properly, after about 20 seconds you should hear a 'click' as the relay drops out which should be accompanied by a slight increse in brightness of the panel lamps. Best check them by removing the lead to each one and measuring the resistance from the connection to earth, should be one ohm or less.

Checking that power is actually reaching them is worthwhile too. I've had several cases of the relay contacts melting themselves out of range.
|
Yes, check power to plugs - relay failure does sometimes occur on these - does the light still come on on the dash? If it's done lots of miles, the exhaust valve clearances will probably have closed up, causing starting problems - particularly with the cold weather we've been having this last week!

Yeah, the light still comes on in the dash guys...........car has done 78,000 miles.
Valve clearances??? Is it a big job?
Thanks for the interest shown.
|
As Confucious once said:- "Light on dash does not necessarily mean power at plugs...."

When I had this problem myself, I switched to Bosch glowplugs. Sorted that out.
Also I noticed my hand fuel pump (looks like a grenade) was loose, had cut itself a little hole and leaking air into the system. Took a lot of turning just to get the engine alive in that case, too.
|
>As Confucious once said:- "Light on dash does not necessarily mean power at plugs...."
Too true.... out with the multi meter.
Valve clearances is a big job as they are direct operated cams and the clearance is adjusted by shims, so the camshaft has to come out to change the shims. 78k is not usually enough to affect the clearances though, so it may well be a power problem.

I have found one way to check the operation of the pre hear system is to get a jump lead fit that to the + on the battery,DO NOT GROUND IT TO EARTH!!! Place the other end of the jump lead on the buzz bar,but before this disconnect the wire from the relay,then pre heat for 10 seconds,no longer as you could burn out the glow plugs,see if it starts,if it does you have a a problem with the pre heat circuit,if it doesn't you can really disregard the pre heat system and look elsewhere.HTH,Andrew...

I do like my Diesels to be Turbocharged for that extra OOMPH!!!!

Hmmmmmmmmmmmmmm......You've confused me now....."buzz bar"????
|
I refer to the piece of metal/wire that links the glow plugs in series.Andrew...

Merry Christmas guys..........
I do hear a "click" around 5 - 10 seconds after the glow plug light on the dash goes out.
I removed 2 plugs yesterday and tested them using "jump" leads from the battery and they seemed to work very well.
Changed both air filter and fuel filter.
My problem was still there this morning........having to hold the key on the starting position for around 20 seconds until the engine eventually fires. Quite a bit of grey/white smoke for around 15 - 20 seconds and then once it's running properly there's no smoke at all!!! Engine seems nice and "tight" with no wheezing or untoward noises.

|
Sorry, I forgot to mention that this problem is only when the car is cold.....first thing in the morning or after my work.....when the car has stood for 8 - 10 hours.

Billone, I had exactly the same problem with my sons ZX last week.
You have probably removed the 2 plugs that are easy to get to.
Because of the access problems to the other 2 plugs they tend to get left.
You will probably find at least 1 of the other 2 are blown.
Take off the bus lead conexion to the remaining 2 plugs & either connect an ohm meter which should read an almost full short circuit of less than 1 ohm, or if you havn't got a meter, connect a headlamp bulb to the battery + terminal then connect the other side of the bulb to the glow plug terminals 1 at a time, the bulb should glow bright if the glow plug is good. Alternatively just change all 4 plugs for either Beru or NGK plugs. I fitted 4 new NGK plugs & engine now starts instantly.
|
Thanks for your reply Dieselnut............
This morning I checked all glowplugs...........all perfect.
My knuckles certainly aren't!!!!
Is there any cold start devices on this 1996 1.9 td engine that may have failed????
|
Billone
I can't see anywhere that says you've proved that there is power at the plugs when the relay operates?
|
Sounds to me like air leaking into the fuel system allowing the fuel to drain back to the tank.
If so I'd check the priming bulb, flexible fuel pipes and filter.
Steve.

Billone,
Is this old thread any help - I had identical problems on my old BX 1.9
