Hows it going cherokee forum. I am stumped. First post for me . Only because every other question has been answered on this site..haha.
I've got a 98XJ. Love the dam thing but it wont stop stalling. Replaced the cps,iac,plugs, wires , distributor, ignition coil, tps. Everything that could be anything that I found on this site. Still doing it.
Happens after its warmed up. Stuttering at first. Give it some gas. Eventually stalls.will start back up, but in inevitably stalls out for good. Give it a good hour. Fired back up again.
Ugg!!..I could use some advise if anyone has another idea.
(Fuel pump) I dont know . I'm ready to put it in the drink. Thanks guys.

 

Is it throwing a check engine light?

What brand CPS did you install?

 

You could drop it off at my place. It should only take me a year or 15,000 miles to figure it out and fix it for you.

 

no CEL. and I bought the mopar CPS from Summit. Its literally driving me up a wall....haha

 

when it stalls and won't start does it have spark and fuel?

 

No spark. Plenty of fuel. The part that gets me is that it will come back after awhile..had it towed today and after the guy dropped it I jumped in and it fired off as if nothing was ever wrong. Crazy man.

 

"No spark."

Sounds like the coil is goiong bad. When this happens, it do exactly what the problem that you are having. Cold, works fine...then heats up and boom.

 

2nd that, mine had cracked, Everytime it rained would foul out all together, found it while running with a water bottle, it would arch against the motor

 

I'll give it a good looking at. Thanks for the heads up.

 

Does "plenty of fuel" mean your injectors are firing?

 

Yes sir. Theres fuel from the rail. I dont get it. I'm not easily defeated but this 1s got me on the ropes

 

i would guess a coil as well. but not sure if ya want to follow my advice, I can't get jeep to start...lol. the only other thing would be some thing is getting hot and loosing connection. no wires touching exhaust or manifold. something hot?

 

Not that I've found yet. Today I shall look over it again more thoroughly I guess. Thanks to all . Appreciate the advise

 

The fuel has to be at a certain PSI or it will shutdown. The fuel pressure guages can be borrowed from any auto parts store. See what the initial PSI is and then when it's running or stalls. I'd be willing to bet it kicks on and slow drops off... that's what mine was doing when I had the same issue you are.

 

Excellent. I will definitely give that a whirl soon as it stops pouring outside . Brutal in new England right now..
