What are the reasons why the Venucia D50 won't start?

[MacAlex]

For the BAIC Senova Venucia D50 that won't start, you can check for reasons such as circuit faults, excessive carbon deposits, fuel pressure issues, etc. Circuit faults or contact issues: ECU CAN bus failure, poor contact at the ECU CAN interface. Excessive dirt or carbon deposits: Too much dirt and carbon deposits can cause abnormal air flow, making it impossible to accurately control the normal intake air volume, resulting in unstable gas content and preventing the engine from working properly. Low fuel pressure and poor performance: Low fuel pressure combined with poor constant pressure performance leads to a low level of system atomization, making the car difficult to start.
