The reasons for a car making a hissing sound but failing to start are: 1. Dead battery; 2. Damaged spark plugs or ignition coils; 3. No gasoline in the vehicle, preventing ignition; 4. Clutch not depressed. The correct steps to start a car are: 1. Place the gear in P or N position; 2. Turn the key to the ON position and wait for about 10 seconds; 3. If the vehicle self-check is normal, proceed to start the engine. Solutions for a car failing to start include: 1. Check if the battery is dead and recharge it; 2. Inspect the fuel pump for damage and repair if necessary; 3. Ensure sufficient fuel level and add more if needed; 4. Check if the engine sensors are damaged; 5. Replace spark plugs and ignition coils; 6. Use a heating rod to warm up the engine oil.
I encountered the same issue when I first got my driver's license last year—the car wouldn't start and made a hissing sound. The hissing noise is usually a sign of a weak battery or poor contact. When the battery is weak, the starter can't turn the gears properly, resulting in that grinding sound. My car was an older model, and the battery terminals had oxidation corrosion, which affected current conduction. When I checked, I measured the voltage at below 10 volts, far below the standard 12 volts or higher. Later, I cleaned the terminals, charged the battery, and the problem was resolved. I recommend that beginners first check the battery's condition, test it with a voltmeter, or ask a friend to help jump-start the car. Avoid forcing the ignition, as it can wear out the starter. For routine maintenance, regularly inspect the battery fluid level and connections to avoid being stranded on the road. Safety tip: If you experience a breakdown at night, immediately turn on your hazard lights and pull over to seek help.
