Hi folks,

Have read a lot about this type of problem - just not sure if it quite matches my symptoms:
Had to be rescued yesterday as my 1995 P38 2.5DT wouldn't start. Started her up yesterday, fine. Coughed and spluttered a couple of times (for the first time). Ran fine/accelerated smoothly over a 9 mile journey. Died twice on tickover at junctions (again, never happened before). Wouldn't restart. Noticed engine management light flashed a couple of times (though done this on occasion before! )
Called out RAC. Diesel being pumped from tank. Diesel NOT coming through from injector pump (having unscrewed one of the pipes and cranked it over. )
Have read about sync problem between ECU and BCEM. But no engine fault codes (besides cruise control) displayed.
> Have a good battery, so shouldn't be that!
> RAC guy didn't think it would be the stop solenoid on the pump.
> Have my own diagnostics, so could I try re-sync with this? How?

Cheers guys,

What diag do you have? If you have a Nanocom then it can be resynced there are instructions how to do this in the Tech archive. Not sure other diags can do this. May not be your problem though unless the battery died on you.. Check wiring to stop solenoid and for air in the clear pipe from filter to injection pump. You have some investigation to do.
 
Thanks for the advice. Will check the diagnostics, sure it's a Britax one. There was one other symptom I'd forgotten to mention... it had just recently developed a tickover problem too. Was hunting at idle ( injector pump would shake quite violently). However, slightest depression of the accelerator and it would stop.

That provide any further clues??

Get some proper diag on it and you may find you have a fuel quantity servo problem. Never heard of Britax diag maybe you mean Britpart Lynx. Get someone with a Nanocom to look at it for you.
 
I had a similar problem a few weeks ago, if my car cut out it would not restart, turned out to be a break in the stop solenoid feed wire.

From RAVE.
Fuel Shut–Off Solenoid (K111)
The Fuel Shut–Off Solenoid (K111) shuts the engine
down if the ECM (Z132) detects a major fault.
Failure of the valve itself does not activate the
warning lamp, although if a short circuit occurs, the
engine will shut down.
 
I have had a tickover problem myself occasionally, showing 750 on the rev counter but sounds like it's running on 4 cylinders. Was blowing a bit of black smoke on acceleration ( It's chipped so over fueling), disconnected No 4 injector and it sailed through it's emmision test yesterday (MOT). Gutless but passed, guess it's like a VW emmision's test bypass. Haven't had the tickover problem since but will have to reconnect No 4 connector as I'm being overtaken by our local Evo crew.Don't know if this will help.

I thought you replaced your number 4 injector last year? You've not jetwashed it?

Number four injector controls timing not fuelling. Some smoke is acceptable as long as it's not like a WWII destroyer.

Well there's a thing, guess I'll have to check the timing when I get a chance. Been too busy, haven't been on here for ages !! I like a bit of black smoke, help's when you overtake a crowd ( mob,gathering,pain, don't know the collective noun for them) of cyclists, drop a gear and give it a boot full. They cycle around here as if the are on the Tour de France.:mad::):)

Same all over. Dressed up in all the gear. I cycled everywhere as a kid with no need of lycra and even cycled to work in a suit for 8 years with no ill effects or issues.

Mine is chipped and drops a bit on hard acceleration, used for cyclists who have been hogging the road mainly. Number four injector sends a point of injection signal to the ECU, the ECU uses this to to compare with signal from CPS to adjust timing modulation solenoid, to alter up or down as required internal fuel pressure being exerted on timing device against spring pressure, to correct any static timing error and set timing to TDC at all engine RPMs. If static is correct timing modulation at idle with a warm engine should be between 45% and 55%. Diesel smoke test should only use 50% engine speed, 2000 to 2500 RPM the days of revving it's balls off are gone. Think they lost to many timing belts using the old method. ;);)

Was it you that posted a link for headlining material/ glue Grrrrrr ? I have done a search without sucess
Click to expand...

Lots of head lining kits on the bay of E if you fancy doing it yourself. Trying to re glue one that has come adrift is not a good idea. Headliner is foam backed and it is the foam portion that is glued to the liner shell. When the foam breaks up cloth detaches and looks shit if glued back up with no foam between shell and cloth.
