    You shouldn't need to reprime - not according to the handbook anyway.

    Diesel fuel system, bleeding
    Attempt to start the engine for a maximum of 60 seconds. If the engine does not start, wait a few minutes and try again.

    Guys it says it needs to bled in the haynes manual or you could damage the injection pump.........but no mention of how to use the Draper hand priming pump........it only mentions in the haynes manual the vauxhall priming pump which is a 12v one which connects to the battery

    any info appreciated

    When I last bought a Draper product that didn't come with a manual, I phoned them up and they popped one in the post for free.

    But as already mentioned, you don't need to prime the system. Just crank the engine over as per the instructions in the Vectra-C handbook.

    I've just looked through the latest handbook which covers the newer diesel engines. If you don't fancy doing it as per the earlier proceedure I posted (which is the correct info for your car), then try the later advice Vauxhall give for the newer diesel engines:-

    Diesel fuel system, bleeding
    It is possible to restart the engine if the tank has been run dry. A delayed start is to be expected. Switch on the ignition three times for approx. 15 seconds. Then attempt to start the engine for no more than 40 seconds. If the engine does not start, wait at least 5 seconds and try again. If the engine does not start, consult a workshop.

    I have no idea if your fuel pump self primes when the ignition is turned, but it would appear the newer Vectra-C's do, hence the mention of 'switching on the ignition three times for approx. 15 seconds'

    The newer diesel engines do self prime, but the 2.0Dti's and 2.2Dti's DO NOT. According to Tis2000 these engines Do need to be primed via a seperate pump. If you try to prime by just churning over the engine you run a high risk of damaging the pump.

    If you are just replacing the fuel filter, after inserting the new filter, top up the housing with fresh diesel before re-assembling the filter housing, thus minimising the amount of air introduced into the system. Then crank for less than 30 secs at a time, with a few mins rest inbetween cranks to let the starter to cool and recover.

    So is a 2003 handbook (that covers the 2.0 and 2.2 diesel engine) incorrect then? I apologise for posting misleading information if that is the case.

    Here's a copy and paste from Tis2000

    Fuel System, Bleed (Diesel Engines)

    L491710
    On Y 20 DTH, Y 22 DTR engines
    Important: It is essential, because of the structural design of the distributor injection pump VP 44, that the fuel system is bled with the aid of the external Fuel Pump KM-948. Bleeder Unit KM-948 must be used on the fuel system after all operations involving the fuel system, e.g. replacing the fuel filter and emptied fuel tank to restart the engine.
    Preconditions:
    – There should be at least 5 litres of fuel in the fuel tank.
    – All the fuel and oil leak lines must be in perfect condition when fitted.
    – It is essential that the battery is charged well.

    Note: Bleeding is not necessary on Y 30 DT, Z 19 DT, Z 19 DTH, Z 19 DTL AND Z 30 DT.



    It then goes on to illustrate the procedure using a powered priming pump attached for 3mins before tryng to crank the engine.



    It seems to apply just to the Y20DTH and Y22DTH, the 2.0 and 2.2 Dti engines.
