Question about 1997 Jeep Cherokee
Hi, this is a hard and frustrating problem to solve. It's bound to be electrical, but where???
Backfiring is an indicator of timing issue, so crank sensor made good sense to try.
I assume when it doesn't start, it turns over. Also assume your engine light is not on.
However, if the engine light has been on and gone off, I recommend you get a scan for the trouble code history--it's just another mode of the scanner. If any code has been set within the past 50 or so trips of the car, the codes should still be in there and they would be VERY helpful to know.
Now, assuming no trouble codes to work with, what I suggest is to do a little troubleshooting when it fails to start.
First check for spark, then for fuel. The procedures at http://www.fixya.com/cars/r5821173-doesnt_car_start_gasoline_engines will work for your car. If you're able to verify a no-spark or no-fuel condition, we can start narrowing down until we find the bad part. Could be as simple as a relay that is weak. I can access your wiring diagrams, so as you start to narrow it down, i can suggest specific parts to test. Please let me know if you have any questions and thanks for using FixYa.

You may have fuel flooding. As a first course of action, please do change the spark plugs and plug wires for better fuel burning.
