The computer grounds the fuel pump relay for 3 seconds to boost fuel pressure on start-up. If the computer does not see oil pressure or RPM it will not continue to ground the relay.
You would need to bypass the relay and see if the pump continues to run, then check the relay and the ground signal from the computer.
The gas gauge problem may be connected or something different.
The connector at the gas tank may be faulty which would affect both the power for the pump and the fuel gauge sending unit.

Sorry brother, it is in the gas tank with the pump. they used filters that are suppose to be good for the life of the vechicle. you can see the plug if you lift up your spare. hope you dont HAVE TO go in there.

Disconnect and replace fuel filter.With filter disconnected have someone momentarily turn key to on position to see is fuel pump is working.Make sure you have lots of rags,a drain pan and safety goggles on

You'll need an OBD I code reader or similar reader to pull the codes. You can purchase from autozone or online.

The in-trunk units have a tendancy to go bad. you can take the cover plastic interior cover off to access the CD changer, un bolt the changer, and visualy inspect the two rollers for debris, or missing /broken gears that move the rollers to take the CD from the CD cartrage to the player. if that looks fine, chances are that the laser went bad (common in rear mount units) and you can order a new one from Jeep, or you can remove it and update the in-dash head to an aftermarket of your choice (& yes you steering wheel controls will still work). you could also fit a more modern MP3 unit where the Changer was.
Testimonial: "thank you so much!I will see if that is the problem and if so, off to the store I go.I actually wasn't to keen on the cd changer being in the back."
