Need help ,running out of ideas

I have a 2000 jeep wrangler 4.0.My jeep started off loosing power on the hwy.I would pull over and restart then it would run fine.The cel came on and I had the codes ran at auto zone.The codes read the plugs,wires ,coil ,camshaft sensor or timing belt.I replaced the plugs, wires,coil rail and camshaft sensor.It ran OK for a few days and then it sputterd and died like it was out of gas.It had trouble starting and when it did it would idle OK until I gave it gas,then it would idle rough and die. I took it to the dealership and they said I needed a computer because it wasn't reading the fuel injectors ,so I had I that replaced.After the new computer I still had the same issue.The dealership said I now needed a new fuel pump and it was also throwing codes for the coil,but the coil code was prob.due to low fuel pressure.I replaced the fuel pump myself and the jeep still has a lot of trouble starting and when it does it misses then dies when I let of the gas.I have spent over two grand to date to fix this prob. and don't know what is left to do.

Right away I thought coils from reading the description. Did your jeep have a surge at all when idling? I would bet that's your problem.

Get some new O2 sensors in it. Buy NTK only.

It's 02 sensors or cat convertor. Sounds like.

I would guess cat converter is plugged up. You can knock the inside honeycomb out and try to see if it runs.

Can you remove the o2 sensors and cat to see if it will run?

Look for the thread by Big Sarge, I believe he had a similar problem that was solved.

When idle do your rpm jump up? When driving dies it go from 1500 to 3000 without giving it any extra gas?

By chance, when you changed the cam sensor did you also change out the camshaft synchronizer or just the sensor? if just the sensor my guess would be its the synchronizer here's a link to a thread with the same symptoms

All right.The jeep is finally fixed.Turned out to be the pin sheared off on my camshaft synchronizer, which caused it to jump timing.
