If you have a meter, testing the CPS literally just takes a couple minutes. Always nice to spend a second to rule that one out....first. There is a write up on that Cruiser did in my signature.

Cool...just if you do have a dvm, it's pretty quick, and some number of new ones are bad. Some will only go with OEM from Jeep on that. I seem to have done OK with an Echlin from Napa. Pretty important that.
