No power going to the starter (2002 jeep wrangler x 4.0 auto)

Hi Tyler.
By run position I assume you mean that you're trying to crank the engine, and that by nothing you mean that there's no sign of the starter engaging. Is this correct?
If you've checked the starter and you are absolutely sure it's getting power you have a seemingly impossible problem, because if the starter is getting the power it needs and you know it's mechanically ok there's nothing in the world that could stop it from cranking.
Are you sure you haven't missed a wire when checking the starter? If the car has an alarm with an immobilizer (also called start inhibitor) it might be activated due to a fault somewhere in the wiring. Some cars might even disable the starter if a critical engine failure is detected. If so the cars diagnostic system should report a fult code when checked. (And, needless to say, an attempt to hot-wire the starter is not recommended until you identify the problem).
I'm really curious about this problem, please notify me when you find a solution!
Good luck!
