2005 engine won't turn over after crash

[coxey2]

Just bought a 2005 altima at insurance auction. The air bags are popped and the engine will not start. When I turn on key the starter tries to spin the engine, but there is some device locking the engine. I put a rachet and socket on the crank pully nut and the engine will spin ccw but is locked in the clockwise direction. How do you reset this system or what is locking my engine? Come on Nissan mechanics lend a hand
