• x18xe1 2000 vauxhall astra 1.8 - petrol filling up cylinders and inlet 28 Nov 2011 (Forum)
    I'm currently having problems with my 1.8 astra,  I recently got the engine replaced as piston failure occurred when driving down the motorway due to low oil, the mechanic said now after the new engine in when He reconnects the battery leads without the ignition on the fuel injectors are staying open and filling the cylinders and inlet manifold full of fuel. The mechanic said it was a ECM so that was another 150pound, So I purchased a 2nd hand brain off him with chip and reader and the mechanic replaced it with NO CHANGE!

• 2002 mondeo TDCI - Mondeo TDCI wont Start 19 Jul 2011 (Forum)
  Hi All I have a mondeo tdci which my wife has been using regularly for the past 2 years with no problems then 2 weeks ago she parked it up outside the house next morning it would not start checked for fuel full tank looked for any leaks and could see nothing, checked the forums & saw that the cam sensors fail so bought one of these and a crank sensor and fitted both. I must admit that I did change the fuel filter at the start of my fault finding but as I have a fast flow of diesel coming out of the return pipe when it is removed I presume that the pump is working and most of the air would be out.

• ford mondeo - Mondeo high idle speed i 53 petrol 20 Jun 2011 (Forum)
    Also a problem which may be related is when in cruise control, the car accelerates, then pulls back like it is starved of fuel the accelerates again.   In my last post I was complaining that I could not get the fuel consumption above 30, well now with this problem you think that the consumption would be worse, but the mpg display shows over 40.

• Ford Mondeo - Mondeo 2.0 TDDI 2001 Wont Start! 20 Feb 2011 (Forum)
  I cracked of the injector pipes and cranked over Cylinder's 1, 3 & 4 just dribble out but cylinder 2 fires out as you would expect it too. I removed the fuel line into the high pressure pump and cranked it over and fuel rushes out which rules out the lift pump. I suspect the fault lies in the high pressure pump but im unsure if its the mechanical part of the pump or the ecu part of the pump?

• Mondeo 2006, Duratec Engine, 2.0 Liter Petrol - Engine Cutting Out / Stuttering Intermittently 10 Oct 2010 (Forum)
  Sometimes it would stutter all of a sudden, the rev needle would go up and down and sometimes the battery light would come as if the car has lost power then it would go again, if i am on the highway the problem is much less noticeable because I think the car catches up again because of the momentum, this has been happening since the past 4 months, i took it to ford and nothing came up on the computer check. I dont think its a fuel related issue but I still changed the fuel filter just to be sure. Any ideas? ...... can it be the the cam or the crank sensor?
