91 Sevelle is operated using an electric fuel pump that is located inside of the fuel tank. Either the pump needs to be replaced, or, you have other problems and the computer is telling the fuel pump not to turn on.

I would suggest that you test the voltage going to the pump as well as the pressure on the lines using a fuel pump tester made for a Fuel Injected Vehicle.

If you attempt to spray a small amount of carb cleaner or WD40 into the throttle body and it tries to start when you crank it, you need a new fuel pump. You can spray a small amount of gasoline into the throttle body, reinstall the intake hose & try to start, sometimes the car will run until the fumes are gone. Use caution to prevent fires due to fuel getting onto areas other than inside the iintake/throttle body. Vent until fumes are gone if you accidently spill fuel to prevent possible fire caused by backfiring.

The fuel tank has to be removed to remove the fuel pump assembly, pumps are available as OEM or aftermarket pumps alone, or complete pump assembly. It is easier for those inexperienced to replace the entire assembly.

Good luck.

Fuel not getting to carborator.

The filter is external. Located on the passenger side frame rail, about 4-5 ft from the tank. round, metal (or if previously replaced-- might be plastic). Are you sure you have a carb? 1988 models were throttle body type fuel injection. If it is TBI, you may not be getting power to the internal fuel pump. Are you seeing a fault code (the check engine light flashing)?

the fuel filter sounds like the problem, are you sure its carborated not fuel injucted because fuel injuction has a regulater for the fuel if it is stuck open you would pump gas to the fuel rail and back to the fuel tank

Truck won't idle

If your truck won't idle then most likely it's your idle control sensor, if it's fuel injected. If it's carborated then the carborator may need rebuilding.
