there is a switch on the clutch linkage. you can see it if you look under the pedol it looks like a black cylinder that slides along the clutch shaft. when this breaks you can't start you Jeep.
Mine broke I had to wait 2 weeks for a replacement part.
oh yeah( it clicks when you press the clutch) so you know it is broken.

a lot of 4wd you have to back up for a few feet to disengage the hubs after you tourn them back to 2wd

SOURCE: when clutch pushed in it makes high pitched squeel

Im a mechanic, i think you will find it will be the clutch release bearing on the clutch fork, when you push the clutch in it will push the fork which will push the clutch release bearing onto the clutch plate which rotating with the engine revs

Sure sounds like a throw out bearing having too much room. Might need adjustment.

Could be one of these-

Dirty injectors
Bad injector/injectors
