Well the codes in today's diagnostic systems don't identify the defective part, only the system or circuit that it's in. Misfire codes can still be a lot of things (as you learned) and it requires a "diagostic tree" approach whereby you eliminate each possibility by testing. This is not always available to the owner's level of equipment or skill. I could see a cam positioning sensor doing this if it were intermittent. Did you check pulse to the injectors with a noid light? If you indeed have fuel in the rail and spark you HAVE to start unless the injectors don't open or you've lost compression.
also we don't know what kind of car this is or the trouble code you got.

This sounds like it has something to do with the security/alarm system? Isn't there a way to disable your alarm?

So you don't have any kind of factory alarm system on the car?

Must be in the distributor then? the ignition module? I know the ignition module resides on the inner fender on the CJs but I don't know about the Cherokee. If you have intermittent spark that's a good thing to check. Is this a 6 cylinder motor?
