I need to replace my fuel pump relay in my car. I can lift up the secondary fuse box that's under my air intake valve, but I can't identify which relay is for the fuel pump. A diagram with the exact location is needed so I can replace it. Thanks

If the service information is correct the pump relay is inside the intelligent fuse box, soldered to the main board. It isn't a separate replaceable part. You replace the complete unit and program it to your car.

It's one of the 3 black ones in the front but I'm not sure which one. Here is a picture of the box.

It does not show us the location of the fuel pump relay, sorry, you might want to remove them one at a time to see when the fuel pump stops working or getting power.

This is the only image that even shows the bottom. They don't even cover the fuses other than the description in the diagrams I posted above. Talked to a dealer tech and he said that on most of them the relays you see on the box are not actually removable, they plug them in and they lock in place inside. What you might try is the self-test that runs the IPDM.

Then see if you can feel the relays as they activate the systems.
