Why does the push-button start not work when there is power?

[CameronLynn]

Possible reasons for the push-button start not working despite having power include: Spark plug issues: Spark plugs are critical components in the vehicle's ignition system. If they malfunction, it directly affects the vehicle's performance and efficiency. Excessive carbon buildup in the throttle body: When the accelerator is not pressed, the throttle body only leaves a small gap for air to pass through. Excessive carbon deposits can block this airflow, preventing the vehicle from starting. Regular cleaning of carbon deposits at a service center is recommended. Starter motor failure: A damaged starter motor can also prevent ignition, similar to a dead battery. Crankshaft position sensor malfunction: During ignition, if the engine control unit does not receive the RPM signal, it will not command the spark plugs to ignite, resulting in a failure to start.
