Ive run into this once before and it turned out to be the intake valve spring was broken not giving the correct seat pressure. not sure its your problem but it looks like you have covered all the other bases.

Change your ignition coil. Mine wouldn't start in the cold. I had to give it gas & it would backfire until it warmed up.

I have a 1990 jeep comanche that does not have spark, i have replaced the crank sensor, wires, coil and module. i have power to the module and the coil tests good.i am out of ideas

Try your camshaft position sensor. A lot of people over look that part. I had the same problem in a 95 YJ and did everything you did, but when I replaced the camshaft sensor it started right up. Hope this helps. Oh yeah, and it is located in the distributer. It is the black plastic disc with the wires comming out. Took me forever to figure out where it was at first!
