2004 lightning fuel pump relay chattering and no start.

Long story but recently I have had an issue intermittently of when I go to start the truck the fuel pump relay with be chattering and the truck will turn over but not start, when you push on the brake pedal the relay will stop but still won’t start. This problem started after the battery shorted and had to be replaced.

Check your grounds behind the kick panels for loose or corroded connections or for body rot. Start on the RH side.

wiring woes are a hassle for sure


sounds like there’s a whole lot more to this story
