Does it act like an electrical or a fuel problem?

It sounds like a clogged fuel filter. A clogged filter would manifest itself with the symptoms you describe... just a guess, and an easy place to start.

If I remember right you have an electric fuel pump .. pull the gas line off, have someone try to start it (make the gas flow) .. there is an amount that needs to be measured in an amount of time to be right ..

I think its like a teaspoon / 10 seconds or something .. can someone confirm for the 4 cylinder?

Actually, i am having the same probs, but with a 89 yj 6cyl,(read article in yj forum), i wouldn't say 4 teaspoons, it a pint for every 30 seconds, that might help, but i am fixing mine, got a mechanical fuel pump and fuel filter, still not working, i might air out all fuel lines and flush gast tan to make sure nothing clogs the lines, hope that helps.

I have had this problem and have had to replace the coil 3 times over the last 3 years. 94 Grand Cherokee 4.0.
I am trying to find out why they are going bad. Does anyone have a clue?
This is not normal.

I am playing with a similar problem on my '95 Cherokee 4.0. It runs fine until the engine reaches full operating temperature and thens dies STONE dead. Won't do a thing until it cools off to about 100 degrees. My problem is electronic, there is no spark from the ignition when this occurs.

I posted this as a question on another section of this board.

Thanks, Bruce

Sounds to me like everyone having these problems all need to check your ignition module. These are the weakest link on your ignition system. It will cause no spark,burned out coils,and heatup and die problems or sometimes it will start and run and then shut off just like you turned off the key any of these problems sound familiar? generally mounted on left fender below the windshield washer jug. Any good auto parts store can check them. good luck hope this helps. Darin

I have an update to my problem. It appears that a corroded wiring harness connector for the "Crankshaft Posistion Sensor" may be to blame. I read about that posibility on another trouble shooting site. Sure enough, when I unplugged my "CPS" harness the pins were corroded.

I have cleaned up the pins and the female receptacles, then applied a dose of "Corrosion Block". I will keep you posted if this is a fix!!!

hmmm,

this cutout when warm sounds like the problem a co-worker is having. His is a 4.2L wrangler. basically it'll start losing power as it warms up. (replaced the obvious things, pump, filter) described as a condition where anymore throttle than 1/2 and the engine cuts out (yes choke plate is all the way open)

So, does this motor have either or both of the ignition module or CPS?

thanks,
Tim

Ooops, sorry! Regretfully, our 4.0s are having an electronic control system problem while your buddy is having goodness knows what! Our system is an instant "die-restart" problem just as though you turned off the ignition.

I would imagine that his 4.2 is carbureted? If so, I would make sure that the EGR valve is working correctly. If you fellows are unsure how to check that, repost the problem here and someone will help you out! Important thing is to remember to KISS (Keep It Simple Stupid) and not overcomplicate the problem.

Take care, Bruce
