I know if I do some searching I'd probably find more than my share of threads, but I'm starting a new one anyway. I have an '03 GC 4.7L V8. The other day I was driving it home and it would randomly die in the middle of driving. I drop it down in neutral, restart and it'd be fine. I tried the "key trick", but it wasn't giving me any codes. It would just say "done". I thought maybe the fuel filter was going bad, so I changed it out. Once that was done, it wouldn't restart. Any suggestions? Bad filter?(I replaced my OEM one with a Puralator and I've heard stick to a Mopar or Wix). Bad sensor? Bad fuel pump?

 

I'm new to jeeps but can you hear the fuel pump run when you turn the key to start?

 

Turns out one of my fuel lines was linked and wasn't allowing the engine to get any fuel pressure.

 

glad you found the problem.
