What's the reason the engine won't start?

There are several main reasons why an engine won't start: 1. Check if components like spark plugs and high-voltage wires got wet due to the car being exposed to rain. If so, dry the damp parts before attempting to start the engine. 2. Inspect whether the spark plugs are damaged: If they are, simply replace them with new ones. Generally, modern car spark plugs have a service life of 20,000 to 30,000 kilometers. 3. Verify if the battery voltage is sufficient: Check the battery's inspection window - green indicates normal operation; black means it needs recharging or maintenance; white means the battery needs replacement.
Last time my car's engine wouldn't start either, and after struggling for a long time, I finally realized the battery was dead. Old batteries or low winter temperatures can easily cause problems. Check if the battery's positive and negative terminals are loose or corroded, and use a multimeter to measure the voltage. If it's below 12 volts, replace it immediately. If you only hear a clicking sound when trying to start but the motor doesn't turn, it's likely the starter motor is stuck or burnt out. Also, don't forget the fuel tank—if the fuel gauge is at zero, it definitely won't start. I made this mistake myself, and filling up the tank solved the problem. Additionally, a blown circuit fuse can also affect starting, so check if the dashboard lights are functioning normally. If you really can't figure it out, taking it to a repair shop for diagnosis is the safest option.
