What are the reasons for the sudden stalling and failure to start of the Beidou Star?

[Cory]

There are two scenarios when the car fails to start: one is when you can hear the starter motor cranking, but the engine does not start. The other is when there is no sound at all after turning the key. There are three main reasons: focus on checking whether the throttle and throttle position sensor are functioning properly. Check if the temperature sensor signal is normal. Inspect the fuel pump relay and related circuits. Here is additional information: Solutions: Visually inspect the outer casing of the battery. If you notice any bulging or deformation, it definitely means you need a new battery. Apart from the battery, other reasons for the starter motor not working could be a damaged ignition switch, a faulty ignition relay, or a damaged starter motor itself. Additionally, check the grounding wires and fuses.
