    Have you tried starting it? They usually start ok after bleeding to the top of the filter

    Open the oil filler cap, and shine a little torch inside so you can see a rocker.
    If you can't see a rocker you may need to lift the rocker cover off.
    Get someone to operate the starter.
    If the rockers rock, the cam belt is NOT broken.

    If the rockers do NOT rock as the engine turns - suspect a broken cam belt.

    Fuel will not reach the injectors simply by priming the lift pump.

    it could have done lots, but it's most likely to have just bent some push rods.
    If so, replace all 8 - they're pretty cheap.

    Gavin,

    When you seek advice on this forum, it's a good plan to take it!

    We all believe firmly in the KISS syndrome.

    If there's an easy way to solve a problem, take it.

    Main dealers think differently - if there's a more expensive way of solving a problem, bill the customer with it.

    FIRST ...... check if the rockers rock!
    Do NOTHING ELSE until you have done that.
    It is so easy to do, so quick, and tells you so much ...
    Take the wire off the STOP solenoid so the engine won't start, which will possibly save you from being splattered with black oil.
    Keep your fingers clear of rotating belts and pulleys too.

    Then you will know what the next route must be, being either
    1. replace the timing belt and probably 8 bent pushrods, or
    2. find out why the lift pump isn't pumping - if it isn't.

    CharlesY

    plumb it all up as it should be change ya fuel filter blow ya lines out, clean out the sedimenter (if fitted) and crank it over it will start if your main pump is ok lift pump is mainly there for higher revs higher loads

    200's and 300's self bleed so tow start or crank it over until it does :p


    if it dont go back to the place you purchased the lift pump and ask for another
