What are the common reasons for engine failure to start?

[DeKylie]

Reasons for the car starter not starting: insufficient battery power; poor contact of the ignition switch; starting circuit failure, etc. The following are related introductions to the starter and engine: Starter: It can convert the electrical energy of the battery into mechanical energy, driving the engine flywheel to rotate and achieve engine starting. Before the engine can operate under its own power, it must rely on external force to rotate. Engine: The process by which the engine transitions from a stationary state to self-operation with the help of external force is called engine starting. Its working principle is based on Ampere's law, a process of energy conversion, where a current-carrying conductor is subjected to force in a magnetic field.
