Review: 03 Expedition fuel pump relay - Ran a wire from the positive on battery to the 4 pin connector which I unplugged.. stuck it in the slot with the green wire with yellow stripe. 4x4 lights blinked the whole way home however it got me home when I was stranded. Good way to diagnose a relay problem before you remove the gas tank for no reason. Be sure to order a fuel filter with this! as it is usually caused by either a clogged filter or a fuel pump that is going bad and getting over worked. 2003 expedition eddie bauer 5.4L
Review: Great replacment for 2004 Expedtion 5.4L Eddie Bauer. - This relay was exactly what I needed. I was having stalling issues and no check engine light. I took the rig to my mechanic who has a very expensive scan tool. He was able to pull a memory code of P0231. I was able to solder this relay into the circuit board of the central junction box (fuse block), saving the $400 not buying a new fuse block. Getting the fuse box out of the car and disassembled to remove the circuit board was more work than removing and re soldering in this relay. I am happy I chose to do this repair myself as it was very cheap, pretty easy, and only took 1.5 hours. Youtube is a great source for how to video.
