The reasons for a car failing to start are: 1. Poor quality or substandard gasoline; 2. Oxygen sensor malfunction; 3. Air flow sensor malfunction; 4. Spark plug carbon buildup; 5. Engine knocking; 6. Damaged water temperature sensor; 7. Engine misfire; 8. Dead or damaged battery. The solutions for a car failing to start are: 1. Check if the battery is low on charge or damaged; 2. Check if the fuel gauge light on the dashboard is on; 3. Inspect the control wiring of the starter for damage; 4. Check if the wiring from the starter to the battery is fused; 5. Check if the starter fuse is blown.
Last week my car wouldn't start either, and I was running around in a panic thinking the battery was dead. Even after hooking up a charger it still wouldn't work, until I later discovered the starter was stuck and had to get a repair shop to help take it apart to fix it. Common causes also include insufficient charge due to battery aging, forgetting to turn off car lights or cold weather accelerating corrosion; ignition system issues like too much carbon buildup on spark plugs preventing ignition; or fuel problems like a broken fuel pump failing to supply fuel. It's recommended to pay more attention to abnormal startup noises - for example, if you don't hear the starter motor turning when starting, you should take note. During maintenance, check battery voltage and connections, don't wait until it's an emergency. Keeping a portable battery jumper on hand can also help in a pinch.
