please help i swapped the engine in my 95 bonneville and now i have no fuel pressure i tried the test lead to the pump and it pressurizes but i have no injectors and the fuel pump wont run i can hear the relay clicking and tried changing the pcm but it didnt make any difference, do i need to get the pcm reprogrammed?

It pressurizes but the fuel pump won't run? I'm confused.

Have you put a 194 size bulb in one of the injector connectors to see if if flashes/flickers when you try to start the car?

Have you checked the fuel pump fuse or swapped the fuel pump relay for one of the others to see if there was any change?

i dont have any fuel pump off the ignition i ran a wire to the test wire and the pump runs and builds good pressure but it still wouldnt start my spark plugs are dry, i put a super charger pulley on it and used the bigger injectors, i tested the purple and white wire and have proper voltage i didnt test the pass key wire but if that wasnt working the starter wouldnt turn over i tried another pcm but still nothing
