Can a starter cause car to stop running?

A starter motor is an essential component of a vehicle's engine system, responsible for initiating the engine's combustion process. While a faulty or malfunctioning starter motor can affect the vehicle's ability to start, it typically does not cause the car to stop running once the engine is already in operation.

Here's a general explanation of how a starter motor works:

1. Ignition Switch: When you turn the ignition key or press the start button, you activate the ignition switch.

2. Electrical Circuit: The ignition switch completes an electrical circuit, allowing current to flow from the battery to the starter motor.

3. Solenoid: The electrical current activates the solenoid, which is an electromagnetic switch within the starter motor.

4. Starter Motor Engagement: The solenoid engages the starter motor's gear with the vehicle's flywheel, which is connected to the crankshaft.

5. Engine Cranking: The starter motor's gear rotates the flywheel, which turns the crankshaft and pistons, initiating the engine's combustion process.

6. Engine Starts: Once the engine starts running, the starter motor disengages and the ignition switch returns to its original position.

So, while a starter motor is crucial for starting the engine, it does not directly control or influence the vehicle's operation once the engine is running. If your car stops running while driving, it is likely due to other issues such as fuel system problems, electrical issues, or mechanical failures in the engine or transmission.
