Re: Question
Absolutely, the 4.0 flywheel/flexplates have the "tone ring" for the CPS to see, none of the 258/4.2's were injected so they don't have tone rings.
You should have reinstalled the flex plate that was originally in the Jeep.

Re: Question
x2.
Reinstall the flexplate that was originally bolted onto the back of your 4.0 and that'll solve your problem.

Re: Question
The tone ring on a flexplate is smaller circumference than the tone ring on a flywheel. Your crank sensor most likely isn't engaging at all. Don't ask how I know this.
