This might apply .. but it for a 1999 Jimmy:
Electronic Fuel Pump Computer Problem6 Cyl Four Wheel Drive

Your symptoms could also be do to other issues ... not just the fuel pump relay. Read the embedded link within the 2carpros response.

Good luck with your troubleshooting

The pump is powered by the relay. The relay is grounded by the computer. It gets a ground signal for the first 3 seconds, then only if the computer sees oil pressure or RPM to know the engine is running.
You should be able to ground the relay and run the pump for several minutes. After 30 seconds you should be at max pressure.
Normal pressure is 15psi for a truck that has throttle body injectors such as a mid 80s model, and 65psi for trucks that have port fuel injection like yours.
You may have the wrong pump.

Thye fuelpump relay is located to the right of the brake booster. this is for a 1991 gmc jimmy (s-15)

I have enclosed a diagram to help locate the relay.

The most common reason for no fuel pressure on these trucks is not the relay but rather the fuelpump itself. the pump is located inside the fuel tank.

There is also a problem with the wiring to the fuel pump, you will need to locate the top of the tank and then off to side of tank is wiring .
This wiring comes off the top of the tank, you will need to check and there is connector problems..
there is one or two ground wires that come off wiring to top of tank which run to frame, check to make sure the grounds are good. if you end up with a bad pump you will see a notice to rewire a new fuelpump connector. hope this is helpful. good day.

There is no reset switch for the fuel pump in this vehicle according to the stuff I am finding. There is a relay located in the power distribution box under the hood. You will need to test that, if it is working then the problem, assuming it is the fuel pump not powering up, is most likely the fuel pump itself. From what I am seeing these vehicles have a history of fuel pump problems from the Anti Rollover cutoff and accident safety switch built into the pump itself.

under relay box . some models is under dash near center of dash

Replace the fuel filter first. When you turn the key on, the fuel pump should run for a few moments, then turn off. If it keeps running, then replace the pump as well. Suggest having the fuel system pressure checked at the engine itself. Hope this helps!

fuel pump relay is located inside the glovebox. there is a pull away panel in the back left corner, should be the center relay.
