thanks mark will do & report back; has this conclusion got something to do with Pin 39 ecu? ive been googling that for ages trying find out anything about it but had no luck.

can i ask if there is a way of telling which the 5V sensor feed is?

thanks again

Pin 39 is the ECU pos supply feed......by all means check the battery charge voltage when reving but, I suspect it will be alright..

Its pin 93 I would be looking at....

sorry ive been away for a while (as well as spending a week in hospital!) but i have an update and it aint good news unfortunatley....

i managed to get the car into an auto electrician today  and printed off everyones kind suggestions as to what the problem is and asked him to look at the car.

he rang me just now and said that he's done the fast running test across the battery and voltage regulator is okay.

he checked Pin 93 & 39 and they are okay and after testing some more he said that the fuel pump in the engine bay (perhaps the ignition pump he's talking about) has an ECU on top of it and that is knackered but i have to get both together which will cost me £700!!!

i haven't picked up the car yet and ive asked him to jot down his diagnosis.

one thing i have noticed is that when the car is cold (in the mornings really) it drives fine so i was suspecting something like the lambda sensor wire earthing or similar; i had a look myself but couldnt see anything myself hence i went the auto electrician route.

i do have some add on wires in the bigger fuse box by the battery (one with a Hella relay); my car has had a tow bar fitted later so im suspecting these are related. but nothing i could see that was bare or possibly earthing.

what i dont want to do is spend £700 or so and still have the problem.... can someone please point me in the right direction as to what i should do next...im not sure on this guys diagnosis and wanted to know if theres anything i should be asking him or perhaps how he got to that conclusion?

many thanks

just picked the car up; he said he checked the wiring loom and couldnt see a short anywhere and checked pin 39 & 93 (which he said was the engine temp sensor??) which are fine. asked him how he got to this conclusion (about the ecu) and he said he's had them before & its common on vauxhalls. not sure if thats a proper diagnostic.

ive been researching on the net and so far everyone who's had the fuel pump ecu go t!ts up have been unable to start the car; mine starts and idles spot on. i queried this and he said its usually non starts but not always....

i can understand how it can be the fuel pump but wouldn't this happen all the time? i.e. even from a cold start?

also can these be repaired? or bought seperate to the fuel pump?

if its fine when cold it could be any number of things but  assuming it has been serviced recently so it doesnt need filters etc changing the first port ofcall for me would dbe the coolant tremp sensor change it!!

Well, to diagnose pump and ECU failure is a cop out, hes not completed a correct and thorough diag as hes not checked the vac setup.....

He should also have looked at the live MAF data whilst actuating EGR valve etc.....it might be as simple as the EGR sticking open....

Omegatoy thanks for the response; its been serviced not so long ago with all new filters & oil. i havent covered many miles since the service (perhaps about 2000 or so). do you know where the engine temp sensor is; i'll get one ordered (i assume a dealer part only?).

Mark (cheers buddy), i really wish i lived near MK!.... i felt really frustrated when he said that his diagnosis is based on past experience; i thought he would have done something to check the ecu. ive been researching and it seems that everyone who's had pump or pump ecu failures haven't been able to start their car.

im not sure what to do now really (short of driving it off a cliff); these cowboys dont even have vac gauges....  ::)

i could do with a list of things to check/clean....

first port of call; buy a haynes manual (will this have the vac pipe setup in it so that i can make sure its all on correct?)
going to change the engine temp sensor, clean the EGR...

im going to have another look for a shorting wire but this time i'll strip off all the intake pipes etc so that i have more space to observe.

is there a way to check the MAF? can i disconnect it and see if the car runs better?

thanks again for all your input everyone

Clean the EGR first....

Follow the vac pipes and check they are all ok....

thanks Mark will do; going to pop down to halfrauds at lunch; i have a feeling a haynes manual will be a very handy thing to have around for the next few weeks;

your advice is very much appreciated mate  :y

will keep you posted.

Place on the net I know about - http://www.omegaowners.com  :P

Sorry, don't really know of further info for this car.  Vauxhall TIS 2000 will have a lot of info in, but is very expensive, not sure how much Autodata has, again expensive.

i took advantage of the good weather yesterday and managed to locate the EGR valve, its just above the intake pipe that comes from the intercooler to the intake manifold.

i have taken some pics and will do write up this weekend as theres not much info on the 2.2dti engine; it may help someone....

anyway; the EGR itself was not mega dirty but the plunger was stuck; got it clean and the plunger was moving again. i also cleaned out the intake pipe as this was quite cruddy. put the car back together and whilst cold it drove better than before; however once temp got up the dreaded jerking/cutting out started again   :(

whilst i had the pipes off i checked all the vac pipes i could see and they were all okay (i.e. none had come off); checked a few extra elec connections that i could see and all were clean. i noticed the intake was quite dirty too but i couldnt take this off as the fuel lines are in the way.

where should i go from here? is there a possiblity that the fault code related to the elecs isnt linked?
also i was thinking about the suggestion of the engine temp sensor.... is this above the thermostat and worth changing?

just been reading around other forums ( :-[) and i came across a thread where a guy had the fault code P1590 but he described it as "Vac solonoid" using Tech2.

link is http://www.cavweb-forums.co.uk/showthread.php?t=128210&highlight=P1590

so my question is would different code readers bring up different descriptions? also is the Vac solonoid where the EGR vac pipe connects to and also the actuator vac pipe?

this is baffling....
