Do a search. Could be a fuel delivery problem.
Good luck.

Welcome aboard

How many miles out of curiosity?

Turn the key on (not starting the engine, just to on, then off)

on off on off on

and watch the odometer closely, it will blink and display numerical codes. Write down any that you see and report back here

Also, you could try checking all the fuses and relays. There's a panel on the passengers side under the glove box and also a box in the engine compartment above the battery.

Also, you could try disconnecting the negative (black) terminal on the battery for 10-30 minutes which will 'reboot' the PCM.

12 means the battery has been disconnected recently, no big deal

55 means the end of the codes

43, 72, 14 I don't know off the top of my head. You can find a list pretty easy though if you google it. It's also listed in a Haynes manual which is well worth the $20.

It _could_ be the crankshaft position sensor like your brother thinks, as this is a pretty common cause of the crank-no-start situation. I actually had the same problem when I first got my ZJ (96) about six months ago -- came here to ask for advice and was told crankshaft position sensor... took it to the mechanic and yep that was it, replaced it and I haven't had any trouble since.

14 : MAP sensor voltage too low /high /or 5 Volt output to MAP sensor open . A OBDII code reader would tell you exactly which one

43 : Multiple misfires , could come from either cylinder . Again , a code reader would be more accurate to pin point the issue . Could be the coil itself

72 : Your cat is operateing at low efficency . You might need a new one .

When you replace the cat you should replace your upstream & downstream O2 sensors also.

Some times when a cat goes bad, the honeycomb breaks up and clogs the exhaust system. The engine won't run very much if that's the case. I think you should replace the cat first and see what happens. Unfortunately, a cat replacement can be more expensive than the crank sensor and MAP sensor put together.

I have a 96 ZJ I6, and I just got a recall notice for the Catalytic Converter in the mail today from Chrysler, Dodge Jeep. Kind of crazy 14 years later, but true. In fact I thought it was for my WK, but it was for the ZJ.

When my Cat went out, it was like my engine was vapor locked. It would barely run, no power, stalling, etc. .

Bottom line dont buy a cat converter before you call to have your VIN run over the phone with either the dealer or the 800 number. If your vehicle's VIN is included under the recall, they will replace it for free.

Recall = E22 reprogram PCM and replace Catalytic Converter

Hope this helps.
