I have a 2013 Jeep Wrangler with an extended crank but always starts. I have replaced the spark plugs, both cam sensors, oil cooler, performed a crank relearn, tested the battery and replaced both key fob batteries and performed a APP sensor disconnect and clean. The plugs, cam sensors and oil cooler were all needed, the other items were done because of the extended crank. It always starts so I am not concerned but just wondered if anyone else has/had the same issue. Any thoughts, let me know.
