If you cant turn over a full 360 you have a problem. This engine has a timing belt I believe. Possibly a stuck valve or cam follower. Remove valve cover and turn dont force. Watch each cylinders valve action until engine wont rotate. Go back other way, check all cylinders in this way until you locate whats NOT moving.If you cant find anything stuck, could be injection pump. Possile but not probable. Last resort prior to teardown, remove timing cover & rotate. Inspect all gears/belt for anything causing stoppage.As valves interfere with piston if out of time or stuck, if there is valve train problem forcing can bend or break valves.
