troubleshooting stuck timing belt

[ajpm26]

Yesterday after getting off the highway, I get to the stop sign on the offramp and my car shuts off. Tried cranking it over and over and it wouldn't move.
I popped my hood looking for things that could be wrong with it and couldn't find anything.
Today I took my timing belt cover off and noticed when I tried cranking it the timing belt wouldn't move on the cam gears at all. Looked wants to move but its stuck, the odd thing is that the alternator belt and ps belt still move so that means the cranks moving.

What could have caused this? Could there be possible damage to the valves?


I'm so lost right now. Going to take the lower timing cover off whenever I get a chance to tow it back to the house.


Thanks

Sounds like a broken timing belt. The accessory belts still spin because they are directly connected to the crankshaft which is spun by the starter on the flywheel.

^^^^^^ what he said. The teeth stripped off of the belt. Happened to me before. You can ether put a new belt on and see if it runs and do a leak down test. Or you can pull the head and rebuild it.
