Your Jeep should have a coil rail on one side of the motor and a fuel rail on the other. There should be a Schraeder valve on the fuel rail where you can verify adequate fuel pressure. I would check at the Schraeder valve (carefully) to see if you have fuel there and it is under pressure. Pressure should be there without cranking the engine. Use a rag so you don't spray gas all over. Another thing to try is make sure the battery is fully charged or jump it to verify a full 12v in the system. There is no reset switch. There is a relay in Power Distribution Center (PDC) called the automatic shut down relay (ASD) that is in the starting circuit controlled by the Power Control Module (PCM). The PDC is on the passenger side of the engine bay. Open the cover on the PDC to determine which relay it is. You may be able to swap it with one of the other relays to see if your symptoms change. I'm going by my memory of my 2000 XJ and my 2003 TJ so you have to verify yours is the same.
