Have to hold the key in starting position for car run?

In most modern cars, you do not have to hold the key in the starting position for the car to run. When you turn the key to the "start" position, the car's starter motor engages the engine's flywheel and cranks the engine until it starts. Once the engine is running, the key can be released and the car will continue to run.

However, there are some older cars that do require you to hold the key in the starting position for the car to run. This is because these cars have a mechanical ignition system, which requires the key to be held in the "start" position in order to provide power to the ignition coil. Once the engine is running, the key can be released and the car will continue to run.

If you are not sure whether or not your car requires you to hold the key in the starting position, you can consult your car's owner's manual.
