It will start though if I pour gas directly down the throttle body.

I have an 87 GMC with a motor out of a 1990 chevy and the fuel pump wont kick on with the key and spray out the injectors. I tried replacing the ignition module, fuel pump relay and the computer, but it will pop ecm fuses sometimes.

Do you
have the same problem?
