With all the problems and replaced bits you are
mentioning, I would suspect a faulty harness or
ground splice issue.

That's going to take a multimeter, disconnecting
the harness, and about 4 hours of your time to
diagnose.

These days most shops only hook up the scanner.
Problem is the scanner can't detect wiring faults
that well.

Re: TJ won't start /run
 

Can you describe more about it not starting? Do you turn the key,
hear it crank, but the engine doesn't turn? etc...

I had a problem with my 2000 TJ where that would happen. It was like
there was a fuel pump problem. It was under warranty at the time.
The dealer had NO IDEA what was wrong. They just started replacing
everything. Fuel tank (fuel pump is part of tank), PCM, etc.. They
would fix it, it wouldn't start again and I would bring it back. I
think this went of for about 2 - 3 weeks where I didn't have the car.
Eventually, I just worked.

I suspect replacing the PCM solved the issue. Overall, I think a
grounding issue or short was causing the failure.
