-You need to provide more info about your car before any one can help you, put as much info (ie: auto/5 sp; mods; milage...) in the vehicle profile.

-Most likely the timing belt's teeth had been stripped at the crank, the crank turn but there's more teeth on the timing belt at the crank area for the sprocket to grap on to, ususally this happen because oil leak damage the belt or belt is old or tensioner/pully worn....
