What are the reasons for BYD Surui not starting?
1 Answers
It may be due to the engine control unit losing network communication or a power supply failure in the engine control unit. Below are the relevant details: 1, Check the electrical circuit: Inspect whether the spark plugs are firing normally and if there is any leakage. Check if the high-voltage wires have high-voltage sparks, and for those with ignition coils, verify if the ignition coils are functioning properly. 2, Check the fuel system: Open the engine's fuel inlet pipe and turn the key to see if fuel comes out. If no fuel comes out, it might be due to a clogged fuel line or a non-operational electric fuel pump. Another rare possibility is the engine control unit being locked due to the anti-theft system activation. 3, Starter or wiring connection issues: These can prevent the car from starting. Additionally, if the battery's starting voltage is below 9.5V, it may also cause the car not to start.
