My jeep sometimes won't start. I replaced the module that programs your keys. I believe they called it Wireless Control Module. When my jeep won't start I have to disconnect the Battery cables and hold them together for 10 seconds then I reconnect them and my jeep starts. I have been told this resets the computer. That makes me think it's not the starter. This doesn't happen all the time. Although resetting the computer (doing the battery cable trick always causes it to start).

Does it turn over and not start or does it not turn over? If it doesnt turn over, you need to test for power at the small wire on the starter when key is in the crank position. Otherwise you will need to test for spark and fuel pressure when it wont start to see what is missing
