1993 Chevy Truck V8 Two Wheel Drive Manual 170000 miles
Truck suddenly would not start this morning. Originally had no fire past distributor. Replaced distributor cap and rotor but not working. Eventually turned distibutor and now have spark at plugs but no fuel. Eventually found no voltage from ECM going to fuel relay on green/wht wire. I applied 12 vdc and activated the relay. Measured 12 vdc on the output gray wire all the way to the fuel pump. Pulled off one of the fuel injector connectors and applied 12 vdc to the injector and it activated but still no fuel. What should the resistance of the fuel pump be? I do not hear it running. Need to know what other sensors if any can cause the ECM to not power this relay and am concerned that there is something else that the ECM is seeing to cause both the spark and fuel problems. Presently I can pour gasoline in the carburator and the engine wants to start so it's a fuel issue at this time. Any suggestions would be appreciated.
Forgot to add that there were no code faults registered.
