There's no flooding. Can smell gas but not wet. Is an oem cs. I did the tune up pulled my plug wires one at a time the spark is orange. Not blue. This is the most confusing issue I've had on a vehicle

Is it intermittent? If so, same thing happen to me last year and it was the crank or flywheel sensor? Some pain in the *** sensor to get to from the driver's side. GL

Sounds like the spark is too weak. Since it did it (not running) with the old and new coils, and the other parts you have replaced, its probably in the wiring that feeds the coil.

I don't know if your Jeep has a ballast resistor, but if it does, it might bear checking out.

The ballast resistor there on the inner fender is actually there to quiet the fuel pump. A guy posting just a few days ago needed to clean his Coil/ICM contacts a second time. In my signature Cruiser has a neat deal there under the "mostly Renix" link. Worth a shot as it's free!

Thanks everyone for all your advice. Was told I fixed the problem with the cps and I guess when I changed the cap it was on reverse. Lol

I'm glad you found it. I guess I was on the right track in post #11.
