Is the overheating issue solved ?
When you have the starting issue is the the sound your hear tapping or clicking ? Where, exactly, does the sound come from ?
Begin with basic trouble shooting of the start and charge systems. Remove, clean, and firmly reconnect all the wires and cables to the battery, starter, and alternator. Look for corroded or damaged cables and replace as needed. Do the same for the grounding wires from the starter to engine block, and from the battery and engine to the Jeep's frame/body. Jeeps do not tolerate low voltage or poor grounds and the Jeep may behave oddly until you remedy this.
Have you removed and cleaned the throttle body and Idle Air Controller ?
