If the pistons don't come up to where they're supposed to, it may be a sign of hydrolock and bent piston rods. If it was hard starting and you cranked and cranked it without it firing you may have done the damage. If a diesel doesn't start after one or two cranks you should shut the water intake and reopen it only after it fires. Did you do this? I don't want to freak you out but if it was hydrolocked you may have major damage.
