How do you test the fuel pump relay on a 92 dodge shadow?

I believe that you can switch the Horn Relay with the Fuel Pump Relay and if the horn no longer works and the Fuel Pump does then that relay went bad... try that, its a sure fire way to know whats wrong... If it checks out good it might be a Defective Fuel Pump.


How do you check the fuel pump fuse or fuel pump relay on a 94 Plymouth Voyager?

The relays are located on the driver side inner fender... I heard that you can take the horn relay out and change it with the fuel pump relay and if the fuel pump works and horn doesnt then you know that it was the relay... Fuses are easy to check, just look at it, if it is broken then its the fuse.


Where is the fuel pump relay on a 2003 Kia Optima?

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.


Where would you find the fuel pump relays on a 1999 Chevy S-10?

I found that the fuel relay is the same number as some of the other relays such as the horn. You can check fuel relay by replacing in the horn relay if the horn works the relay is good.

The fuel pump relay is in the distribution box under the hood. It is located between the horn relay and the shut down relay.


Where is fuel pump relay on a 1995 Chevy Blazer S10?

The Fuel Pump Relay and The Fuel Control Relay which are both exactly the same relay is located in the Glove Box under a little cover on the upper left side. The Fuel Control Relay is the left relay and The Fuel Pump Relay is the right. To test these relays, swap them and then try to start the vehicle, or blow the horn. If the horn blows then use that relay for the pump and you may at least drive the vehicle where needed! If the vehicle starts, then replace them as a pair. (between $14.00 - $20.00 at local parts store) Correction, the fuel pump relay is on drivers side and the horn relay is on the passengers side.


How do you check the fuel pump relay on a Chevy Avalanche?

switch it with a relay that works, like your horn relay or simulate the relay with fused jumper with 12 volts from your battery. 87 on your relay is your out to the fuel pump. putting 12 volts to the point of contact where 87 would be should start your fuel pump.

Where do you find the fuel pump relay switch in a 92 Dodge Dynasty?

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.

Where is the fuel pump relay on a 1990 Geo Tracker?

The fuel pump relays are mounted on an "L" bracket underneath the ECM. Both have something to do with the Fuel pump. Be careful not to get it confused with the horn relay it is in the same vicinity (under the dash on the drivers side).
