How To Replace a Fuel Pump Fuse

Do you think your fuel pump is shot? Before you replace it, check the fuse. You may just need a new one to get your car working again. If that's the case, here's how you can replace your fuel pump fuse.

Step 1

Read the car's manual. Replacing a fuel pump fuse is just about the easiest repair you can do on your vehicle. You just need to know where the fuse box is on your car. Generally, it is found on the driver's side, below the steering wheel, or in the glove box. Before you go tearing away at the interior of your car looking for hidden fuse boxes, just refer to your owner's manual. It will easily direct you to the placement of the fuse box in your car.

Step 2

Remove the fuel pump fuse. Once you have located the fuse box, you need to remove the cover from it. Your owner's manual should have a diagram that lays out what each fuse powers. But if it doesn't, also look on the cover for the fuel box. Sometimes these have a diagram showing the location of each fuse. When you are able to locate the correct fuse for your fuel pump, remove and discard it.

Step 3

Put in a new fuse. Now all that's left to do is replace the burnt out fuel pump fuse with a new one. You'll need to visit your local automotive store and purchase a new fuse for your fuel pump if you don't already have on in your collection. Just remember that not all fuses are the same, so be sure to replace it with exactly the same type of fuse that you removed. (Not sure? Check your owner's manual for the exact fuse needed for your fuel pump). Gently press the fuse into the proper location until you feel a firm ‘snap'. This ensures that the fuse is properly connected and will run the fuel pump.

Step 4

Start your engine. With the new fuel pump fuse in place, replace the cover on your fuse box and try to start your car. If you're lucky and your car starts, then you're done. Clean up your tools and bask in your accomplishments as a seasoned mechanic! If, on the other hand, you have trouble with your newly-replaced fuel pump fuse, it could be for one of several reasons.

If your car starts up with a new fuel pump fuse in it, but quickly dies, it may be that your fuel pump itself is dying. It might just be clogged too, and in need of a good cleaning. Or it may be an entirely different problem, such as something to do with your electrical system. If the car doesn't start altogether, it could be that your fuel pump is already blown. In that case, you'll need to replace it. But don't rule out the possibility that the fuse might just be a dud. Always try a second fuel pump fuse before you run out and replace your whole fuel pump.
