I can only catch it sometimes. And only when cold. The IAC is working again now with the new ecu, and freshly refreshed sensor grounds. It catches itself better than I can now. But when it dies now, it's warm, not hot, and will die sooner and sooner the more I restart it, until all it does is...

Any chance the asd is getting warm and failing? I think I'm going to replace all the relays tomorrow. If that doesn't do it I think it's time for the dreaded shop

Did that today, got the coil to test bad when warm. Still didn't help.

Didn't fix anything... same issue still.

talked to my Chrysler Tech father in law last night, and he agrees that it can't be much other than the ECU at this point, so we're throwing one at it tomorrow.

Relay is good. Tested it the other day.

Ballast has been bypassed for years, pump itself is brand new, and fuel pressure is good.

Cleaned the contacts better, and it starts and runs again, but still dies after a couple minutes of idling. CPS tests good. My multimeter sucks, but looks to be putting out almost 1v when cranking With it unplugged. We're looking at ecu now, right?

Well color me disappointed. I had autozone test the coil, and ICM. Both test good. Now it's looking like the issue goes back to the computer. I'm going to do a more thorough cleaning of the contacts and see if that does anything, but if not, that means computer right? I have no spark... I...

ICU, not ecu. Lol the coil seems to be fine, but I'm not sure how to test the icu. Each of the pins seems to have some sort of path to the two contacts for the coil, and I feel like that's not supposed to happen. I put my ohm meter on each of the connectors, and touched each of the pins, and...

How can I test the coil vs icm to know which one I need?

Did the icu/coil refresh and now it won't start at all.....

I'll do the icu/coil refresh. Probably tomorrow, but we'll see how I feel. I just had surgery monday

New cps is good, but I'll test it to be completely sure. It's starting fine almost every time, leading me to think it's not cps. Also, I'm leaning toward ecu because my IAC hasn't worked properly in years. I tricked it into closing, then used to be able to just hold the rpms up with my hand...

I don't have the little bracket, but it's not touching the exhaust either.

Okay, I've actually done all of those already except for the coil/icm. I'm really leaning toward failing ecu at this point. I have good spark, and no missing. It just up and stalls out for no apparent reason.

Cruiser, your link isn't working for me. It might just be because I'm on my phone (no Internet in the new house yet) ARE They THE Same As Your mostly Renix Tips On cherokee forum?

Cps is good. Not to mention, it's the third one in a week. Replaced the old one thinking it was the issue, didn't solve anything. Noticed the wires touched the exhaust and melted slightly, so I replaced that one hoping that was the issue, and now I'm on this one. What are the chances of...

Didn't really want to start a new thread, but my phone won't let me search for some reason. Anyway, 90xj, 89 mj motor, ax15 trans. Like the title says, I have a random stalling issue that I can't wrap my head around. I've checked/tested/replaced everything I can think of that would cause...

Alright, that makes WAAYYY more sense. haha Big difference!
