KK starting problems

[talleybird_kk]

Every thousand miles or so I'm having an intermitten starting issue. I'll turn the key and it just keeps cranking. No start. I'll try again and have no problem. It doesn't happen often enough for me to be concerned, but should I be?

If it is intermittent, this going to be a pain to find unless it flags a DTC. To point you in the right direction, I would venture to say it is the WCM that is acting flaky..

I have a JK and it did the same thing. Every once in awhile it would just turn over and not start. When I stopped and tried again, it would start.
I know you have a 3.7 and my JK has a 3.8, but they both have a crank position sensor, this may be the culprit, it was on mine.
The dealer changed out the sensor and it has not done it since.

You are very welcome! I hope this fixes your problem. Even if it is a minor problem, it is a very annoying one,......it was to me anyway.
