Hi What was the engine code of your old motor and what is engine code of the replacement engine.Have you noticed the unions that the fuel feed and retun pipes are scewed to the pump,are differant,there is an inlet and outlet union if you have them in the wrong place you will have a problem similar to yours

hi they are both abl engines out of p reg t4 vans, the fuel feed and return going on to the diesel pump are colourd clear and blue, they are the same as the ones that came of, the pipes are shaped to only fit in one place, reading up is there a sensor somewhere i may of left of, i had the hole front of the van, i cant c a maf sensor on it,it does seem diesel starvasion,
