The 1990 G20 Chevrolet Van fuel relay switch is located on the front of the fuel tank. The relay switch is next to the fuel pump.
Inbetween the battery and distributor.
The fuel relay on a 1992 Chevy G20 5.7 liter, 350 is under the hood attached to the firewall at the top, just under the wind screen
they r 2 relays one under dash looks like 4 way flasher relay the other 1 is under hood mounted to left of windshield washer pump
Not sure about a 1992, but a 1993 G20 fuel pump is definitely in the tank. It's an electric, turbine-type in tank design. My understanding is the 1991-1994 are all the same.
The fuel pump relay switch is located on a metal tang under the hood on the top center of the firewall. It's pretty much directly above the radiator area.
The fuel pump will be located inside of the fuel tank. If you need to replace the part, you will most likely need to go through the trunk.
Mounted in the fuel tank.
if you put in a new fuel pump and the fuse still blows check the fuel relay under the hood on the firewall,,its oval in shape,,,, disconect the relay and turn the engine over if the fuse doesnt blow then the relay is bad,,if it does then you have a short in the wire harness its easy to follow from the fuel pump to the relay good luck
On my "96" 1500 Pk-up. Its under the hood, on the diver's side, in the fuse box.
Try replacing fuse and/or fuel pump relay. That's what I did to my '95 G20 and it started right up.
In the fuel tank
