The other day, I went out to start the Jeep and It cranked okay but it will not stay running. At first i thought it might be the battery since the day before i noticed that when i would turn my heater on high my voltmeter would drop like a rock, almost to the red zone, but when i would turn it down, it would return to normal. I did some more research and found out it could also be either the fuel pump, fuel pump fuse, or the timeing belt has broke( Oh, I hope that is not the case). Any ideas guys?

The 4.0 has a chain and gears so its probably not that. I would check the TPS, Vacuum lines or even something as simple as the air cleaner...Tj
