Long Cranking Time 16 JKU

We bought this 16 JKU new in 15. Purchased the extended warranty and it’s paid for itself already. Currently at 120k miles. Since about 60k the engine would randomly take a long time to crank before starting. Always started though. For the past 40k miles, It’s been getting worse. Zero codes. Had dealer replace plugs at 100k. Cleaned injection system etc. it’s been to 2 different dealers, they’ve had it over a week the last time, said it never happened to them. BS, it happened the next morning. Now, sometimes she’ll crank for 20-30 seconds, hiccup then die. Still no CEL or stored codes. Sent a video to the dealership service mgr. he says he doesn’t know what to do. Suggestions, still under life warranty.

Ask to test the fuel pump or replacement if the crank sensor

Those were my thoughts as well, they said they can’t test anything unless they have a code or can duplicate the problem. I guess I need to find dealer number 3.

This never happened on any of my Jeeps, but I had the same symptoms you have on one of my pickups and changed the fuel pump and it is back to starting first crank. Just a thought.
