1987 GMC Truck Repair Question
Asked on December 3, 2011
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.
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.

Check the injectors if its pulsing-by using a noid lite

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

Sounds like the computer injector driver
