It is possible that the car's ignition switch is broken. The ignition switch has the ACC position, the ON position, and the START position. Turning on the ACC position is to connect the car's electrical equipment, such as audio, lights, etc. The ON position is to connect the ABS (anti-lock braking system), AIRBAG (airbag), oil pump and car ECU operating power, etc. And START means to begin. You said the car couldn't turn the ignition off. The most likely reason is that the car's ignition switch is broken. For a detailed answer, I suggest you go to the 4S store to see a maintenance technician.

To determine if fuel has entered the cylinder, disconnect the spark plug and press the air filter hole firmly with your fingers. Dry the engine several times and smell the fuel with your fingers. Determine whether there is an air leak in the oil supply channel and change the position of the shock absorberr to see if it can start.
5. Problems with the power conversion system and gas distribution system: Disconnect the spark plug and press the air filter hole with your fingers. If no compressed gas comes out after a few empty starts, it means there is some. a problem with the power conversion system or gas distribution system.
