What causes the car to not start with flashing lights?
1 Answers
Reasons why the car cannot start with flashing lights include excessive engine carbon deposits, or faults in the carbon canister or carbon canister solenoid valve. Below are detailed explanations: Excessive engine carbon deposits: Due to excessive carbon deposits and dirt in the intake tract, the cross-sectional area of the air passage changes, causing the air-fuel mixture to become too rich or too lean. This leads to 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 result in a too-lean mixture during startup, making it difficult to start. Carbon canister or carbon canister solenoid valve failure: If the carbon canister or carbon canister solenoid valve malfunctions, it will continuously enrich the air-fuel mixture, causing the yellow light to flash and preventing the car from starting.
