I have had three Power Wagons with engines that were stuck. I removed the spark plugs and filled each cylinder with Marvel Mystery Oil. After a few days I used a bar and pried against the teeth on the ring gear until the engine would move a little. Gradually this resulted in each engine turning freely and being able to start each one. Worth a try.
