If the starter motor is spinning, but the engine is not rotating, it is likely that there is an issue with the starter drive. The starter drive is responsible for engaging with the flywheel and turning the engine over. If it is defective, it will not be able to do this. A hydrostatic lock or a cracked crank pulley would prevent the engine from turning at all, while a dead battery would not cause the starter motor to spin.
