engine wont hand crank

[RRTDiesel]

Recently replaced oil pump and the engine was hand cranking but now that i have the engine bolted back to the transmission the engine will not turn. transmission is in neutral and i am dumbfounded....why might it be doing this now?

Standard or automatic?

I would suspect that the torque converter was not fully inserted into the transmission when the two were re-connected. It causes the shaft to be jambed against the pump casing, often causing damage to the transmission. It will have to be separated and checked for damage. There are a few threads on here about just such an instance. You might also want to check the tech library for information that might help. good luck.
