First thing I'd do is pour an oz or 2 of gasoline into her and SEE FOR SURE she was getting gasoline..
If she don't pop and snort then I'd know for sure she had a spark problem.
I'd get my wife to hold a plug wire and see how high she jumped when I turned the engine over.. If she starts beating me about the head and shoulders.. I'd know the timing was off and THAT was the problem.
The timing is controlled by the computer.. Mostly it gets it's main information from the CPS to know when to spark correctly.
Even if it was an iac or a tps the engine should at least start.. or nearly start.
Then last but not least the timing chain could have jumped a cog..which is not unheard of but not common with Jeep engines.
