Fuel pump works. Checked fuses 32 and 34 and PCM relay. Nothing in owners manual Identifies fuel pump relay or fuse ( my 03 f150's fuel pump relay is under the hood, but not this one). I checked safety fuel shut off switch. Just curious if anyone knows if I checked the right relays and fuses or if this model is notorious for any other problem causing fuel pump to not receive power. My truck is a 2004 F150 stx extended cab 4x4 with a 4.6 liter. The more detail on answers, the better. Thanks for any help.
