Reasons Why a Gasoline Engine Won't Start
2 Answers
Gasoline engine failure to start is caused by carburetor blockage, impure gasoline, or severe carbon buildup. Below are detailed explanations of these causes: Carburetor Blockage: Clean using compressed air and CarPro cleaner. Impure Gasoline: If the gasoline is impure or contains water or other impurities in the fuel tank, the engine may start at idle but speed becomes unstable when accelerating, and stalls with larger throttle openings. Clean the fuel tank and replace with genuine 93-octane gasoline. Check if the kill switch is in the ON position and verify the fuel tank switch is open. Severe Carbon Buildup: Severe carbon deposits on pistons and cylinders lead to poor compression. A complete disassembly and thorough cleaning is required.
My car runs on gasoline and often has trouble starting. Possible reasons include an empty fuel tank or a faulty fuel pump causing fuel supply interruption; spark plug carbon buildup or damage leading to ignition failure; a dead battery unable to power the starter; a clogged air filter affecting air intake into the engine; or high gasoline viscosity in cold weather causing fuel mixture issues. Usually, I first check if there's enough fuel, turn the ignition key to listen if the fuel pump is working; if there's no sound, the fuel pump might be broken; then test the battery voltage should be above 12V, if not, jump-start or replace the battery; finally check if the spark plugs need cleaning or replacement. These steps handle most issues, the key is not to frantically crank the engine, which can damage components, and to seek timely repairs for safe driving.
