Can you turn the engine over with a pry bar on the crank?
It might be too hard to do with all the plugs in, so bear that in mind.
It's a pain to remove the plugs on a Hemi but, you could remove 8 of them - one per cylinder, to see if you can turn the engine over by hand.
Did you just go out one day to the truck to start it and it just wouldn't?
Was the truck running OK previous to this issue?
Oil levels, coolant and no overheating issues previously?
If the engine won't turn over "by hand", she's siezed in some way.
I sincerely hope it doesn't come to that.
