Why does jeep turn off after 2 seconds of idling?

Have u checked fuel pressure, are u getting any check engine codes

Yeah the fuel pressure is fine, an no I haven't even hooked it up to the computer

Does sound like a fuel problem. On mine I had a inline fuel filter on the passenger side, under the back door. Cheep fix replace it see if that works. I also had to replace the fuel pump in the tank. But thats all I got.
