What are the reasons for a push-start car failing to ignite at the first attempt?

Reasons for a push-start car failing to ignite at the first attempt: 1. The smart key is out of power. When the smart key has no battery, its transmission power is very low, making it difficult for the car's sensor to detect it, thus preventing the push-start from completing the ignition. 2. The gear is not in P (Park) position. For automatic transmission vehicles, manufacturers usually specify in the manual that the gear must be in P position when starting the engine. 3. The steering wheel is locked. After the car is turned off, if the steering wheel is rotated a certain angle from its centered position in one direction, it will lock. In this locked state, the push-start function will not work. 4. The battery voltage is insufficient, out of power, or damaged. Failure to start may be due to a drained battery caused by leaving the headlights on for a long time or the battery reaching the end of its lifespan.
I've been driving for over ten years and have encountered several instances where the push-button start wouldn't work. The most common issue is battery-related – if the battery voltage is insufficient or the terminals are corroded, you'll only hear a clicking sound when pressing the button. Last time I experienced a starter motor failure, the distinctive whirring sound of free rotation was particularly noticeable. Insufficient fuel pump pressure can also prevent ignition, especially when parked on a slope where the pump can't draw fuel. Sometimes in extremely cold weather, frozen fuel injectors make starting impossible, which is particularly troublesome in winter. A minor but often overlooked detail is not pressing the brake pedal firmly enough – modern vehicles won't activate the system without sensing sufficient pressure. If there's been aftermarket electrical modifications or if the anti-theft system malfunctions, the car might inexplicably shut down, requiring battery disconnection and reconnection.
