Don’t try to work on your vehicle while it’s turned on since you could get shocked.
If you can’t find the fuel pump relay, check your vehicle’s manual to see if it lists the location.
You won’t be able to start your engine after you remove the relay because the fuel pump won’t work.
You can also try cleaning the terminal ports on the fuse box with the wire brush as well. Wet a cloth with an electrical contact cleaner and rub it into the prongs if you can’t clean all the corrosion off of the prongs.
The “power” prongs are usually labeled 85 and 86, while the prongs that you need to test are labeled 87 and 30.
You can buy a multimeter from your local hardware store. The ohm setting on your multimeter measures the resistance between the terminals on the relay to check if they’re working properly.
You can buy jumper wires from an automotive or hardware store. It doesn’t matter which wire you connect to each terminal.
If you don’t hear a clicking noise when you attach both of the jumper wires, then the circuit inside the relay isn’t working properly.
You can also get multimeter probes that have alligator clips on the end so you don’t have to hold them against the prongs the entire time.
Depending on the ohm range of the multimeter, the reading may also be a small decimal, such as 0. 001 or 0. 005. If your relay functions and has correct readings, then you may have a different problem with your fuel pump or electrical system.
