The relay has a coil and contacts, when energized, it holds the contact closed, thus the fuel pump operates.
The fuel pump relay is under the front hood on the Passenger side, inside a cover held on by screws. the fuel pump relay is Blue or light green. The white one is the "main" one. It has to work to make the fuel pump relay to work when starting the car with the key. To test the pump, read diagram on fuel pump relay and use jumper wire to close the switch and if pump works you can hear it running in the trunk at that cover plate.
No You Will Not Be Able To Do This. The Relay Is Required To Make Your Electrical System Work For The Fuel Pump. The Relay Is A Switch Unto Its Self. It Shuts The On And Off As Required By The Fuel System. Even If You Were To Bypass It. The Pump Would Run All The Time. Suggest You Install A New Relay
Chevy does not have a reset switch. If you installed a fuel pump and it still won't work, Then you need to check the wiring harness at the pump where it plugs into the top of the tank. Chevy had a problem with the wire connector at that point.If that checks out okay, then check the fuel pump relay and fuse.
Relay switches are typically in the fuse box compartment underneath the hood usually on the driver's side (~not~ the fuse compartment under the dash) You will see a black plastic box. Pull the cover off. On the under side of cover will have a list of what each fuse, micro relay, and mini relay are for. You will see an entry for the fuel pump relay or possibly just "fuel relay". How to test your relay switch. Some of the relays in the fuse compartment will be exactly the same relay. For instance the horn relay can be (not in all cases)the same type of relay for your fuel pump relay. So if you think you have a bad fuel relay switch... change it with the horn relay switch... then honk your horn. Does it work? (Of course make sure your horn works in the first place). If your horn works with the fuel relay switch substitute... your problem is not with your relay. If your horn does not work.. presto... you have a bad relay. If your relay continues to go burn out... you'll need to find out why. Possibly a bad ground.
