What are the reasons for the Geely Vision's one-button start not working?

[OLyla]

Geely Vision's one-button start may not work due to the following reasons: 1. Excessive carbon deposits: This could be caused by too much carbon buildup in the idle motor, intake tract, intake valves, and combustion chamber. 2. Overly rich or lean air-fuel mixture: Excessive carbon deposits and dirt in the intake tract can change the cross-sectional area of the air passage, leading to an overly rich or lean mixture, resulting in abnormal combustion or engine shaking after starting, or even failure to start. Alternatively, issues with the fuel injector, such as leaks or excessive carbon buildup, can cause a lean mixture during startup, making it difficult to start. 3. Faulty carbon canister or carbon canister solenoid valve: A malfunction in the carbon canister or its solenoid valve can also make starting difficult.
