Why Does a Sedan Emit a Gasoline Smell When Starting?

[DeStella]

The reasons for a gasoline smell when starting a sedan are: 1. Incomplete combustion during startup; 2. Aging rubber hoses in the engine compartment, leading to leaks; 3. Insufficient air intake by the throttle, causing incorrect air flow information, affecting fuel injection quantity, resulting in increased fuel consumption and a gasoline smell; 4. Poor sealing or uncleaned residues after disassembling and reassembling the fuel pump; 5. Leaks in the gasoline carbon canister or fuel pump rubber ring. Solutions to address the gasoline smell when starting a sedan include: 1. Replace the throttle; 2. Replace the carbon canister or carbon canister solenoid valve; 3. Clean the engine interior; 4. Replace the fuel injector; 5. Open the solenoid valve; 6. Replace the carbon canister rubber hose.
