Without a scan tool you may have to guess which it sounds like you have been.I would say from what you say happened and what you have replaced that you are looking at a crank sensor or a PCM issue. I would look at having a scan tool hooked up to see if you have communication with the PCM or ECM and if so what codes are present. in todays computer controlled vehicles the scan tool is you best friend it can point you in the right direction from the beginning. hope this is helpful.
P.S. you might check fuel pressure its a long shot but tha did cross my mind.
You don't say what size engine the vehicle has. If it is the 4-clyinder, you may have a broken or stripped timing belt.

I just had this problem and replaced the camshaft sensor, crankshaft sensor, and coolant temp sensor. i replaced these items because of high mileage. try these but first check your relays located under the hood on the passenger side. sometimes they get hot and fail.

Replace the crankshaft position sensor
SOURCE: 1996 Jeep Cherokee. Random occurence cranks but no start.
there is also a cam sensor and throttle position sensor, any codes, fuel npump can test ok but jeeps are noted to have the fuel tank sock come off in the tank and the fuel pumps can have intermittent starting problems. I hope thiis helps

Try locking and unlocking the drivers door using the key. Usually that will re-set the security system. Also try the rear hatch lock as sometimes that is used instead of driver door.

The
Engine and Automatic Transmission (not applicable to manual
transmissions) in this vehicles drive train are fully electronically
controlled by a computer called the PCM and TCM (Power Train Control
Module, Transmission Control Module). When a problem like this or
other drive-ability related problems occurs the computer stores a
record of the problem (there are of course some exceptions to this,
like the fuel pump, engine coolant temperature sensor and MAF sensor
for instance) in the form of a fault code in its memory, to read
these fault codes you must have the systems memory scanned with a
special tool. Once the fault code(s) are read you then must perform
the appropriate diagnostic testing to find and resolve the problem(s)
DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED
THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT
MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for
correct spec for your make and engine type.
