Engine No Crank / No Start – No Sound
The engine does not crank and there is no sound when attempting to start. This indicates a complete electrical failure in the starting circuit, likely due to a dead battery, faulty starter, or ignition switch issue.

Ignition switch or neutral safety switch failure – prevents starter activation.
