What are the reasons why the BYD S7 won't start?

Reasons why the BYD S7 won't start: 1. The battery is dead, possibly due to prolonged headlight use or the battery reaching the end of its lifespan. The solution is to replace the battery immediately. 2. Check the vehicle's spark plugs. The proper functioning of the spark plugs is crucial for the car's performance and efficiency. The solution is to unscrew the spark plugs and clean them. 3. Incorrect gear position. For automatic transmission cars, the gear must be in P or N position to start. If it's in R or D, the car won't start. Some manual transmission cars also won't start if the clutch isn't depressed. 4. Fuel quality issues. Owners should use standard gasoline. When refueling outside, a gauze can be used to cover the fuel nozzle to filter impurities. 5. Excessive carbon buildup in the car can also prevent it from starting. The solution is to frequently drive at high speeds to reduce carbon buildup.
I've been driving a BYD S7 for several years and have encountered the issue of the car not starting several times. The most common problem is with the battery, which might be old, have insufficient charge, or have loose or corroded terminals. If turning the key doesn't elicit any response or you only hear a clicking sound without the engine turning over, it's likely the battery needs replacing. Ignition system failure is another major cause; spark plug carbon buildup or damaged high-voltage wires can affect starting. If the fuel pump is faulty and can't supply fuel, the car won't start either. A stuck or worn starter motor can also cause issues, and sometimes the anti-theft system might mistakenly lock the car, requiring a key re-match. I've also experienced problems due to aging wiring or blown fuses, which beginners might easily overlook. Regular maintenance is crucial; check the battery voltage and clean the terminals monthly, and pay extra attention to the battery's condition in winter to avoid sudden breakdowns and inconvenience.
