Where is the Fuel pump fuse located?

Hi,

Actually, for the fuel pump to get power, there are two fuses and two relays that need to be working.

I attached the schematic for the fuel pump below. I will try to explain how it works.

When the key is turned on, power from the 10-amp fuse in the dash fuse box sends power to the main relay (primary side) and actuates the relay. From there, power goes through the secondary side of the main relay from the injector fuse in the under-hood fuse box which runs to the fuel pump relay secondary side.

Power from the fuel pump relay isn't made available until the powertrain control module provides a ground path to the fuel pump relay primary side which actuated the relay and then allows power to run to the fuel pump.

I imagine you are ready to yell at me at this point. I have no idea why they need to make things so complicated. To add insult to injury, there is an inertia fuel shut-off switch that can turn off the fuel pump in the event of an accident. And yes, they can fail. You can see it after the fuel pump in the pics.

Okay, when you check the fuses, make sure the key is in the on position when checking the engine fuse. Otherwise, it won't have power. The injector fuse should have power at all times.

When checking, it is also important to check for power to and from the fuse. Here is a link that explains how that is done:

Let me know if this helps or if I made your headache worse. LOL Also, let me know if you have other questions.

Take care,
