most likely your Crank Position Sensor. I just replaced mine yesterday, same symptoms your experiencing. I'm guessing its a 4.0L motor since you didn't specify.

First find the connector unplug it them plug it back in 90% the jeep will start after this if not use a 3ft ext and give it a smack (its on top of the bellhouseing) then do the plug thing if still not starting change it . Thier about $40.00 and I always carry a spare. I ran fro three years doing the plug unplug thing. I hard wired it when I changed last itme
