So, I posted a few weeks ago about how my jeep would run for about an hour then just die. After it died, if I let it sit for about 10 minutes it would run again for hour then die. A few people suggest it was the Crank shaft position sensor. Well, I have been dragging my feet on fixing it until lastnight.

I went to turn over the jeep and it started/ran for about 2 minutes then died. After that it wouldn't turn over again. I plugged my OBD2 reader in and no codes were produced except the ignition one.

Everytime I turn the key it sounds like it wants to start. The ignition sounds fine, the battery has a good charge on it, and it has gas with stabilizer. Anyone have any ideas what might be causing this to happen? Any ideas on what I could check to narrow the problem down? Could it still be the CSP?

Thanks

It sounds like you waited to long to change out the CPS. If you do a search on here you can find a few write ups on how to check them. Just remember that doing the cps check isn't always 100% reliable.
A bad CPS will give you all the symptoms that you have described. When you get one get it from the dealer. Many people on here have had results with the cheaper ones bought from the auto parts store.
Good Luck.

I am amazed a CPS could be causing all this trouble with no alarms being generated.

I know with 3 of my XJ's It never had any code when the cps went out.

I'll just replace it instead of testing since, from what I'm reading, it can test good but really be bad.
