Reasons for the fuel supply system failure in BMW 5 Series causing failure to start: 1. Check if the battery has power: It may be due to power loss caused by leaving the headlights on for a long time or the battery reaching the end of its lifespan. Generally, it is recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also lead to vehicle circuit failures. Checking for a dead battery is simple—just press the horn. 2. Check if there is fuel: If the fuel gauge shows below the red line, the car naturally won't start. Also, pay attention to the quality of the fuel. Always refuel at reputable gas stations, and when traveling, you can use a gauze to cover the fuel nozzle to filter out impurities. 3. Lack of antifreeze: Some owners add water or low-quality antifreeze, which can cause the entire cooling system to freeze in extremely cold winter conditions. This can lead to a cracked engine, preventing the car's water pump from functioning, resulting in failure to start and damage to other engine components.
