1992 K 3500 won't start, no fuel, poor fuel in throttle body it starts. is there a relay for the fuel pump or did the fuel pump die?

Remove the air cleaner and watch the injectors while someone cranks on the the engine. If no fuel comes out, go back to the gas tank and remove the cap. Stick your ear to the filler neck and have someone turn the key on. The pump should run for a few seconds and shut off. If it fails to come on, check fuel fuses. If it does come on, remove your ignition control module from the distributer and have it tested. More than likely it has failed and is no longer sending a reference signal to ecm and it will not fire the injectors.
