I HAVE AN 87 WITH A MOTOR OUT OF A 1990 CHEVY AND THE FUEL PUMP WONT KICK ON WITH THE KEY AND SPRAY OUT THE INJECTORS.

1987 GMC Truck

It will start though if I pour gas directly down the throttle body. I tried replacing the ingnition module, fuel pump relay and the computer. But it will pop ecm fuses sometimes.

I tried the nod lite test. They dont pulse but I have 12 volt to them.
