AnswerTells the fuel pump when to kick on and off.

The relay has a coil and contacts, when energized, it holds the contact closed, thus the fuel pump operates.

If the fuel pump relay switch is bad then the fuel pump will not be turned on. Think of the relay like a light switch. If the switch has a bad connection then the light doesnt work.

Most cars have a fuel pump relay switch located either under the hood in a fuse/relay box or on the firewall.

If the relay is bad, then the fuel pump will not work.

Yes, it is a fuel pump relay.

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

It should be located on the driver side fender... 2nd relay back (because theres a row of relays in that panel) I heard that you can switch the fuel pump relay with the horn relay and if the vehicle starts and the horn wont work then the relay is bad.

User Avatar

if it has a roll over switch it may be in the trunk over the fuel tank and it could be a fuse or relay if that doesn't work may be a bad pump.

does not have one. that,s right does not have one, if you suspect fuel pump issue check fuel pump relay first.The main engine relay and fuel pump relay work in tandom with each other. Replace in pairs, $ 16.00 ea at kia dealer.Tech bulletin about this.

yes, replace the relay then check for power, if it doesnt work take out the pump and check it manually by connecting the lead and ground to a battery(watch for sparks, it can ignite the gas in the pump). replace pump if necessary

User Avatar

Make sure you have voltage at the pump. If you do then the new pump is defective. If not, the fuse is blown or the fuel pump relay is bad. Where is relay?

User Avatar

Are you sure its the relay... Does the car receive spark... if not it might be the ASD Relay located on the finder, under the hood next to the battery, its the last relay there.... the ASD Relay sends power to both coil and fuel pump, if its bad it will cause both not to work.

It does not have 1. If it won't work, then check the fuel pump fuse and relay. You may also have a bad ignition module in the distributor causeing it not to work. Could be a # of different things.

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.

User Avatar

check the relay first,and then the fuses if this does not work the fuel pump will most likely need replaced

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.

Blown fuse, defective fuel pump relay or the fuel pump has failed.

User Avatar

Blown fuse, defective fuel pump relay, or the pump itself is defective.

User Avatar

Where is the fuel pump fuse and relay on 1994 BMW 525i and how can I test to see why my fuel pump won't work

User Avatar

Possibly loose connection or the relay is failing. Replace the fuel pump relay first.

User Avatar

Either the fuel pump itself is defective, the fuse is blown, or the fuel pump relay is defective.

User Avatar

Blown fuse, defective fuel pump relay, fuel filter clogged, or the fuel pump is bad.

User Avatar

there is not one! if pump does not work it is a fuse, relay, or a bad fuel pump.
