I left my 05 4.0 TJ idling while I got out to close the shop gate and it died. No sputter it just quit. Cranks but no start. It’s been running like a top before this. Did the basic checks of fuel, spark and compression. I took the intake hose off and put some fuel in the throttle body and it fires right up. So I figure it’s a fuel issue. I switched out the fuse and relay and still no start. I removed the fuel line from the rail without having to depressurize the line. I cranked it over and no fuel came out of the line. Could there be anything else to check or is a new fuel pump in order. 114K on the odometer and I assume the pump is original. I’m too lazy to search the site but what is the recommended replacement? The thing that sucks is that the tank is full. I have a 4 day trip out in the Mojave starting on the 15th so I need to get her up and running ASAP.
I’ll add that there are no codes.

Full tanks kill pumps... it's the hot fuel pump in an empty tank getting shocked by cold fuel.

Find a Mopar if you can...and if you can spare a kidney.

You can swap just the pump out. Write up in the resources section on how to do just that.

I tried but the Bosch pump from Brazil lasted me two weeks. And my plastic cage is so brittle it was hopeless.

I went the opposite route...put the cheapest pump assembly i could find on Rock Auto...a Brute Power...made it over the Rubicon and a road trip there and back to Oregon and a lot of forest roads since.

I will say I'm not happy with where the float is set...six gallons isn't cause for a fuel light and the float has gotten stuck or disconnected twice on hard, hard jolts...but started working again 15-20m later after more jostling.

YMMV.
