Hope somebody can help. Got a corrado vr6, non starter. Replaced ecu relay, fuel pump relay, in tank fuel pump and external filter. Have checked fuses but will check again. The car has been sitting for about 7 years. It has an immobiliser on but it seems fine. The engine turns over and does fire up if you put fuel in the inlet manifold. Should the new fuel pump make a buzzing/ whirring noise? I have checked, and there is power going to the fuel pump wiring clip, if only for a split second. Any help suggestions would be very much appreciated. Thnk you, Scott.
