V8 two wheel drive manual 170,000 miles.
Truck suddenly would not start this morning. Originally had no fire past distributor. Replaced distributor cap and rotor but not working. Eventually turned distributor and now have spark at plugs but no fuel. Eventually found no voltage from ECM going to fuel relay on green/white wire. I applied twelve VDC and activated the relay. Measured twelve VDC on the output gray wire all the way to the fuel pump. Pulled off one of the fuel injector connectors and applied twelve 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 carburetor and the engine wants to start so it is a fuel issue at this time. Any suggestions would be appreciated.
Forgot to add that there were no code faults registered.
have the same problem?
