Cadillac Repair: 1993 Chevy S-10 w/2.8 V-6 Fuel system, fuel delivery system, fuel pump relay

Question
My vehicle will not get fuel out of the throttle boddy after it sets for a few hours after the vehicle has been driven. The fuel pump has been changed and fuel filter replaced as well as the Fuel pump relay. I was wondering could the ECM can act up just on the fuel delivery system or have I overlooked something? The ground wire is clean and tight at the frame rail for the fuel pump. and it runs just before I attempt to start, but no fuel dumping into the intake at the Throttle Body when I attempt to start, Thanks In advance, Richard Stewart

Answer
OK, Disconnect BOTH of the fuel injectors 2 wire connectors.

One wire of each connector is a GROUND and the other is a 12 volt voltage line.

Attach your test light to a wire within the connector and the tip of the test light to the other wire in the same connector. Try and start the car and the test light should flash ON and OFF repidly, Does it ?.

The injectors have battery voltage on one wire of each injector at ALL times when the ignition is ON. The other wire is the GROUND wire which is pulsed by the computer.



Let me know.
