98 tj just stop running. Now won't start.
 
This morning pulling out of my drive way my jeep just quit. It won't start back up, it will crank but won't fire. I did a quick search am I going in the right direction with the cps?

Its a for four banger. Has fuel.
Any suggestions?

Thanks guys

That is one of the symptoms of a bad CPS. Have you got spark?

Update.

When cranking i smell fuel at the intake.
Swapped the relay for the fuel pump that didnt help.
Also disconnected the battery to clear the computer.

Im about to check spark.

I had this happen on my '97 SE while doing my electric fan conversion. My clues were a) I could no longer hear the fuel pump and b) the gas gauge was suddenly reading empty even though I had 3/4 tank. There were no codes. Swapping a different relay for the fuel pump did nothing. Turns out I blew a fuse in the interior fuse box (behind the glove box) which protected the circuit going to the power distribution center underhood (and thus the fuel pump relay). Once I replaced that little fuse, everything came back to life.

I would think a faulty CPS would trip a code--have you checked for any fault codes? This should always be step #1 when trying to diagnose a problem.
