Why Can't the Car Start?
2 Answers
Reasons why the car cannot start: 1. Fuel supply system issues: clogged low-pressure fuel line, loose or leaking pipes, air in high-pressure fuel line, poor technical condition of injector, incorrect injection timing angle; 2. Starting device issues: power supply failure, poor contact of electromagnetic switch, poor contact between starter motor commutator and brushes, clutch slippage in starter transmission mechanism; 3. Insufficient cylinder compression pressure: cylinder gasket damage causing air leakage, valves not sealing tightly causing air leakage, piston and cylinder liner wear causing air leakage; 4. Insufficient air intake: clogged air filter element; 5. Anti-theft system issues: the vehicle's anti-theft system can also cause some frequently overlooked faults in the fuel supply system.
I've been driving for fifteen years and have encountered several instances where the car wouldn't start. The most common issue is a dead battery, especially when parked outdoors in winter, as low temperatures significantly reduce battery performance. Last time, my wife forgot to turn off the interior lights, and the next day the car wouldn't start at all. There's also the starter problem—you can hear a clicking sound but the engine doesn't respond, usually due to worn carbon brushes or a faulty solenoid. Fuel pump failure is another hassle; if gasoline can't reach the engine, it won't start. Additionally, severe engine carbon buildup or oil that hasn't been changed for too long, causing excessive viscosity, can make piston movement difficult. I remember one time the car key's anti-theft chip malfunctioned—no matter how much I turned the key, nothing happened, and it had to be reprogrammed in the end. If you run into battery issues, carrying a portable jump starter can be a lifesaver.
