ZJ: 5.2: Does it have a CPS?

[whodat]

My zj left me stranded this weekend, 115 miles from home after a wheeling trip. Went back the next day and it ran like a champ. Drove it home, drove it to the store, ran fine. This morning (30*, ice on the window) it again failed to start. No codes, has fuel pressure, first time it did it I pulled a plug and it had some spark. I searched the archives for CPS info, but it was all in relation to the 4.0 I don't want to bring it to the dealer, but I also don't want to throw parts at it without having some idea of what's wrong. Also, it has near 90k miles, so I'm fiuring that it's probably coincidental that it happened after a wheeling trip. Thanks in advance!

yes, it has a CPS.
If it has spark though, the CPS may be okay. If the CPS was bad, it wouldn't have a spark. And a bad CPS would throw a code.
Check Not sure what it could be .. the ASD relay is a good suspect, but if you have fuel and spark then it is supposedly doing its job. But maybe in the process of checking things it got 'better' .. I hate intermittent electrical faults 'Could not reproduce problem'.
