Where is fuse panel for fuel pump for 1997 gmc safari

Did you replace the fuel filter, and do you know for a fact the pump is getting power and ground when you turn the key switch on ?

I don't usually do diagrams due to copyright laws.
From the fuel pump you have a gray wire and a black wire.
The black is ground and the gray is power from both the pump relay and the oil pressure switch.
The oil pressure switch provides power to the pump once the engine starts.
At the relay, you have a green and white wire that provides power from the ECM with the key switch on. You have an orange wire that provides power from a 15amp fuse.
The gray wire going to the pump, and a black and white wire for ground for the relay.
The ECM provides power for 3 seconds when the key switch is turned on to boost line pressure for startup.

Check and see if the fuel pump relay is stuck.

its inside the gas tank

check fuse and fuse panel connections

at the fuse panel under the hood or under dash

Could be fuel pump, is the pump running when you turn key on, you should be able to hear it. You are likely going to have to take it to someone with a pressure gauge to make sure it is getting proper fuel pressure. Fuel pumps commonly go on these vehicles

Have your fuel pressure checked.Sounds like pump or relay is out or fuel filter restricted too much.Remove the gas cap and put your ear to filler neck while someone turn's the key on,you should hear the pump running.pump run's for about 8 second's to prime fuel rail then shut's off till cranking.

relay is under hood in plastic fuse case, look at scematic for relay location in the case

if the gauge is still stuck when the van is off, try whacking the dashboard right above the gauge. PLEASE RATE MY ANSWER.
