    My numpty mate ran out of diesel, got the car going again with roadside assistance (don't know what they did exactly to get it to start) then following day engine wont fire again!

    I know the fuel filter may need priming but seeing as the car was running b4 i dont know if thats the only problem...

    Ideas?

    Oh its a veccy di 97 reg

    Dont know if this is going to help, but this is what Mr Haynes has to say.

    1 It is not always necessary to manually
    prime and bleed the fuel system after any
    operation on the system components. Start
    the engine (this may take longer than usual,
    especially if the fuel system has been allowed
    to run dry - operate the starter in ten second
    bursts with 5 seconds rest in between each
    operation) and run it a fast idle speed for a
    minute or so to purge any trapped air from the
    fuel lines. After this time the engine should idle
    smoothly at a constant speed.

    2 If the engine idles roughly, then there is still
    some air trapped in the fuel system. Increase
    the engine speed again for another minute or
    so then recheck the idle speed. Repeat this
    procedure as necessary until the engine is
    idling smoothly.


    3 If there is difficulty in bleeding the system.
    then it may be necessary to contact your
    Vauxhall dealer as they have equipment (Tool
    No. KM948) to bleed the system.


    Other thought is blocked fuel filter due to crap thats been laying around in the bottom of the tank coming through.

    Alternators can cause funny electrical problems when faulty and the earth to chassis can be poo too

    Well 99% sure its the alternator.

    Got the car pretty cheap with the idea that sum stuff needed doing.

    When starting the aux belt screams like mad for 20-30 secs then settles down, horrid clicking/buzzing sound comes from around the alt so im pretty sure its that.

    One question does the altinator always charge the battery or does it switch on and off?
