Question about 2003 Jeep Grand Cherokee
When a faulty coil gets hot, it quits working, you have a 3 pack and they hardly ever go out in packs, usually one at the time and it will be misfiring and loss of power before the engine dies and the check engine light will come on. If check engine light is on, have the codes scanned to find out which coil is defective.
Otherwise, I would go for the ignition module, it is the flat part in wich the coils sit on. Check connector and wiring.
Check for spark in all 3 colis when no start condition occurrs, if no spark in nither one, replace ignition module.
