    astra 2.0 d problem

    hello all, i wondered if anyone could offer me some advice on my w reg astra 2.0 ltr diesel , ive owned the car for 3 trouble free years and apart from routine servicing it has cost nothing .
    however a couple of mornings ago i went out to it and it would not start , it turns over as per normal but refuse`s to fire or even offer to fire .
    i slackened off a couple of injector pipe`s to check fuel delivery but all there is is a feeble dribble as opposed to a definate spurt from the pipe.
    although im a truck mechanic with many years experiance on both heavy and light vehicles i have to admit the modern small diesels are new to me .
    so i got a mobile mechanic out of my local paper to come and diagnose the fault hoping that he would use a code reader on the car but no ! , instead he just said he knew this model very well and the fault was the injector pump u/s , replacment cost circa £2000 + £800 fitting cost .
    is this so ? im not to sure of the engine code but i do know its the lower bhp model .
    he also said that obtaining a s/h pump was out of the question as they are coded to the car ? is this true ?.
    i dont want to get rid of the car as apart from this problem it has been a very good motor so any offers of help or pointers would be gratefully recieved , are there any particular problems with these models that could cause this problem btw it had a new fuel filter fitted around 4 mths ago .

    rick.

    p.s congrats on a great forum its very interesting and a lot of the members seem to be very knowledgeable on these models .

    thanks for the replies fella`s , as yet ive not yet tried to tow start it but it did cross my mind , there is a very good fuel injection specialist about 12 miles away in manchester that may be the way to go at least they will have the gumtion to put the code reader on it i would think .

    Sounds like the injector seals. there known for it.
    Also its the cheaper option instead of putting a pump on it.
    Replace the injector seals first

    I have heard of fuel pump troubles but never come across one. Every single none start i've seen with these engines has been those injector seals that v8 rick talks about.

    They're not the actual copper seals at the nozzle, but further up the injector is a two piece assembly (top of injector to a horizontal fuel bar), and bolted/sealed with rubber seals, to fit underneath the camshaft. These can & do suffer with allowing air to draw in over time and cause non start. Generally you can actually get the car to start (easy start etc...) and it'll fire up no trouble again until left overnight again.

    A little fiddly to do, as you have to unbolt/lift up the cam to gain access, but definately the cheapest option & most probably at fault.

    Regards, Nick.

    rick.

    I onced serviced a vectra I had and after it was done was a pain to start.
    Sorted it once the injector seals was replaced, so yeah they can go straight away

    thanks for all your comments and advice fella`s , hopefully i can get time in the next day or two to have another look at the car , i hope i ve not bored you all yet but a couple of thing i could do with knowing first please , is it true that the pumps on these models are coded ? and do they have an inertia switch same as a petrol to cut the fuel pump in case of hard impact like an accident ? if so where is it located cheers .
    ahh !!! i almost forgot if , its a injector pump fault , would it not put the engine management light on when trying to start it ????

    rick.
