I have replaced the battery, starter, sensor, spark plugs, distributor cap and my jeep still will not start. First it started by the wipers, heater, and radio starting only sometimes so I replaced the fuses. After I replaced the fuses it stop starting. It does not even click or make any kinda noise.
In a 96 Jeep not many sensors are involved. Basically Fuel and spark delivery at right time should start car if your Starter is able to crank the Engine.
If engine is cranking then the battery is Okay. Check Spark directly at the spark plugs and fuel pressure at the fuel rail. You may pull out one spark plug and check spark out of engine.
Try spraying Starting fluid in Air Intake while cranking. If Jeep starts then not enough fuel is being delivered by fuel pump. If you find no spark at plugs then check circuit for starter relay, Crank sensor/cam sensor problems.
A kill switch or bad Alarm system can also cause this problem.

I am having a similar problem. But I cannot get a spark. Engine cranks but without a spark the engine won't start right ? I'm am doing my best to troubleshoot step by step but for the life of me cannot find a service manual for my 1996 Jeep Cherokee XJ, 2.5L, 4 cylinder, 5 speed ,Manual transmission, 2 wheel drive 2 door SE model ? Am leaning towards ECM because I replaced crank shaft sensor, bought a new coil but still no spark ? Does anyone have a step by step from beginning to end for my XJ. Because I can't even find videos for a four cylinder cherokee manual transmission ? I'm not the rich enough to keep buying parts I don't need. Any info would help ? Diagrams , videos, links , manuals , anything. I'm more then willing to get my hands dirty. I have been to quite a few wrecking yards looking for my XJs ECM. I'm finding out that almost every other year besides 1996 is very common. And the motors on 100 % of the ones that I have seen are 6 cylinder. Any suggestions. The motor is still strong. Before this issue Jeep was running good. I did have to jump one of my injectors. With help of course. I guess I'm in denial. I'm going to order the ECM. But am afraid that if that doesn't fix my problem I'm all out of $$$ and out of answers. I'm just just thinking out loud I guess. I will post my results when I get ECM hopefully by 02/16/18. Thanks.

SOURCE: 199 Jeep cherokee stalls without warning
Does it start right back up after it stalls? make sure all conections are tight at fuel pump, sounds like it could be loosing ground at pump, or hot lead is loosing its connection at pump.Also fuel pump relay could be getting hot and quits working.
SOURCE: jeep cherokee sport,engine wont start unless worm.
Check the temperature sensor...it tells the computer when it's cold, and changes fuel mixture accordingly. (same as a choke used to do)
Just curious...If it only starts warm, how do you get it warm???
SOURCE: '97 Jeep Grand Cherokee Ltd 4.0 liter; Will start but cuts off.
have u replaced the crankshaft position sensor? do u have any computer trouble codes? Kragen or Autozone will run the test for free.
SOURCE: Distributor cap wiring diagram
1-5-3-6-2-4 firing order. #1 is located for you on the cap, go clockwise.with the wires.cylinders 1through 6 are front to back
SOURCE: spark plug wire position on distributor cap
1-5-3-6-2-4
ALL Jeep 4.0 motors use this firing order. Any year, any model, high output or not.
Also, the spark plug wire placement on the cap, in a clockwise direction from the post nearest the engine block is: 6-2-4-1-5-3.(to the left side of the number 6 post, there should be a hold downscrew or strap for fastening the distributor cap to the distributor.
