Hi Mike,I have changed the fuel filter for a genuine Delphi and checked the visible fuel lines. No change. I am waiting to get the car back to the specialists to investigate again. Still no fault codes or warning lights.Which sensors are used to control the idle speed because I think that the ecu is getting either false or conflicting information during and shortly after start. It is as if something mechanical was sticking, releasing and then sticking again. From an electronics point of view, if a sensor was working right on its operational edge and maybe skipping pulses I thing that could be at least one of my problems. I described the problem to the local Delphi agent and they said fit new injectors. The specialists looking at the problem claim that the last time it went in they removed and tested the injectors and that they are fine! Only one of them can be right and I don't want to pay £700 for another set if they are fine. So if we assume that it's not injectors, fuel filter or lines, which sensors should I be checking or replacing? The fuel line sensor is indicating an in speck pressure during crank and appears to work correctly on a road test. Does that eliminate the high pressure pump and regulator?There must be a set of circumstances that exist to allow the engine to run at 600 rpm and ignore the throttle, but what are they?Best regardsMartin
Hello again, this is MIKE who you spoke with before...
I was just about to go off on a break when I saw your message /question - I thought Id best just let you know I have it..
Many thanks for letting me know, talk later.
Hi there... Ok, Ive read through whats been happening - do you mind If I come back to you on this... I need to digest what you have going on as well?
Ah right , our posts crossed- so yes, I'll get back to you asap ...
Thank you , you will get a message when I repost -or check back later.. Rgds for now.. MIKE...
Hi, It looks like I missed you earlier. I didn't receive any indication that you were back. Can you call me on XXXXXXXXXXX when you are back or is that against the rules? best regards, Martin
There has been confusion over your question...I couldnt get back to you
I cant contact you by phone Im afraid , its against the rules - your number has been botted you will notice.
Can you please tell me which posting you want to work with - I need to know before we carry on?
They are both the same problem, arn't they?
~~ Yes, but we aren't allowed to have duplicate questions open - I was told you had asked to close this one... but you re used it apparenlty...
Just trying to resolve the original problem. never used just answer before and don't know how to re open the original, if that is what I need to do.
Ok no problem - are you happy to carry on here ?
I don't know. Just don't want to keep paying for new chats
I understand, we can carry on - I have info for you anyway - basically your problem is looking like the fuel pump on the engine - at least at this stage.
Its a common fault on these - I know you said it has had a pump ( and injectors etc ) before - but , it is looking that way -
OK, how do I check that?
the best way forward on this one now I feel is to locate a Diesel Specialsit and have them test things for you, rather than just replace items - they have all the equipment to check that, it is specialsied equipment Im afraid - general garages dont have it.
They might find something else - but its def going to need testing that way.
OK, just don't trust any of them. You know far more than me but I can't see how it can be the pump, injectors etc when after a few seconds, sometimes, everything is fine. My background is not motor engineering but generally mechanical parts either work or not. If they change their performance it is normally due to some external influence, ie a sensor. Is it not possible to identify what can or maybe what can't cause my problem?
The live data from the fuel pressure sensor says that the pressures are OK. How then could it be the pump?
Its not so that the parts on the system either work or dont.. faulty parts give faults / intermittent troubles and so on... The pumps on these are a common issue - I have a Tsb on this -give me a moment to get it for you -
The specialist that it has been to claims to have the best diagnostic kit available and they can't find the problem.
Im sorry I cant pull that tsb but basically it was referring to pump faults internally, worn rollers in the pump that cause the erratic idle etc.
The only other thing I can think off , is is if there is a Software problem in the ecu/ pcm. There are often updates that can be done - you would have to ask Ford on that one - the local dealers.
I have seen some of those reports but they seem to list a different fault scenario to mine. My local Ford main dealer is in Lichfield and although I have no personal experience with them I have heard the common horror stories about them. A bucket full of replaced parts, big bill, fault not fixed!!
Would I be better of back at Delphi?
Whats the Dephi place you have - is it a specialist place?
Delphi I meant.
http://www.dieselspecialists.co.uk/ Did that link come through, if not its Swadlincote Diesel F.I.S. Co. Ltd. Could you please comment, ie answer your own question as I don't know. They have a good local trade reputation.
yes I have the link -
That looks to be an excellent place to get your issues sorted-
Last of the Summer Wine country!
Certainly that looks ok , I would go there with it and tell them what the issue is - with the equipment they have, they should get to the bottom of this for you for sure.
The injectors were out and tested 3 weeks ago and they clam that they are OK. Most confused.
Hello again Martin - Im afraid the CHAT system appeared to have crashed so I have had to switch us out to the QA system - I didnt want you to think I had just left you !That said Martin, right now I have to go off for a couple of hours - I have a meeting I should have been at for 7 ! so I have to go now - I will check back later though with you in case you replied - ... Best Rgds, MIKE..Ps - if you do want to get back to me, use the reply in this post XXXXX, XXXXXt open a new question.. Rgds, MIKE.MIKE41123.7723135764
