    hi folks

    the brother and myself put a engine into my a4 2.5 tdi quattro all going well until the grand finale starting the engine it turns over fine but wont start,we tried all the obvious things bled it still no joy,now think is electric problem there is a loud buzzing like a tattoo machine coming from the injector pump and it doesnt stop even when you take out the key any ideas what it could be.

    tks

    Is the fuel pump the original one to the car, or did it come with the engine?
