So have you checked for codes?
I would maybe do that first. The Jeep can hold onto codes, some think it cannot unless its an OBDII, but mine did when my tps was bad on my YJ. There was no CEL, but there was a code.
Anyway, do the key trick and see if there are any codes, remember 12 and 55 don't mean anything important.
