1998 JGC stall/not starting issue

Been going down the list, CPS is next. Just trying to narrow it down. It usually happens in warmer weather or when the engine is hotter. After replacing the TPS, complete tune-up, replacing MAP sensor, ignition coil and cleaning AIC it was working MUCH better. Didn't stall for a whole month. The weather has warmed up a bit and now it's BAD! Have heard some hints about vacuum lines and grounds but don't even know where to start. Any ideas? Recently had the fuel pump and relay replaced.

When the humidity is high it is easier for current to find a stray path to ground. When the ground path that is normally used by the current is weak, the humidity (water is a great conductor) will provide an easier path for the current, taking it into places it doesnt belong causing cross feeds across components.

So, if you havent cleaned your grounds yet, it probably should be next.

And check all the vacuum lines for leaks. My dad's 04 WJ was acting really badly (cutting out while braking, cut-out when idle etc.) and it turns out a vacuum line was completely disconnected.

Thanks Bannerman! That was also one of the top ones on the list!

Finally fixed!!

I went down the list of 12 and got up to getting the CPS installed. Didn't fix it. But the Diesel Repair Shop next door ran some codes and finally pin-pointed the Auto Shutoff Relay. They replaced it and it's been running great for 2 days now. It had been out of commission since July 2013. Feels great to be driving it again!

My mistake

I guess I have so much information and threads and lists that I got them confused. So many others on the thread and some people I actually know in person who have had the same problem swore it was the CPS. It was inexpensive and fairly easy to do so I just did it. Actually, I had the garage next door do it because I'm not fond of tight spaces. When they were done installing it they said it had not fixed the problem. They then ran the codes and did some tests and determined that the culprit was the Auto Shutdown Relay. Popped in a new one and she's been running great for 3 days after being out of commission for almost 1 1/2 years. Luckily, this didn't cost me anything cuz they like me!
