Why can't the BYD G6 start with one-button ignition?

[NovaLee]

The following are the reasons why the BYD G6 cannot start with one-button ignition: 1. Battery depletion: The characteristic symptom is that the starter begins to turn but lacks sufficient speed or power, or the starter only makes noise without turning. Low temperatures in winter or forgetting to turn off certain electrical devices can cause the vehicle to fail to start, especially when used for long periods of short-distance, low-speed driving in winter, leading to battery voltage dropping below the rated value and the starter failing to operate normally. 2. Fuel flow obstruction: Do not wait until the fuel is almost depleted before refueling. The characteristic symptom is the absence of oil pressure in the engine's fuel supply pipe. 3. Poor ignition system performance: The characteristic symptom is poor fuel atomization in the cylinder due to low intake air temperature, especially in very cold weather.
