The flywheel is a heavy metal disc that's attached to the end of the crankshaft. When the engine is running, engage the flywheel to keep it rotating smoothly. Tightening it back down with enough torque shouldn't let the flywheel spin around at all really, even if the key is sheared. No spark could be from either a bad coil or sheared flywheel key, which would also make it kick back and hard to start. I'd venture a guess that when the engine suddenly seized up it sheared the flywheel key right then.
