How to Solve the Problem of a Car That Won't Start?

Here are the solutions for a car that won't start: 1. Check if components such as spark plugs and high-voltage wires have gotten wet due to rain. If so, dry the wet parts before attempting to start the car again. 2. Inspect the spark plugs for damage. If they are damaged, simply replace them with new ones. 3. Verify the battery voltage. A green indicator means the battery is in good condition, black indicates it needs recharging or maintenance, and white means the battery should be replaced. The steps to start a car are: 1. Insert the key into the ignition and turn it to the second position (power-on mode), then wait for the system to complete its self-check. 2. Shift the gear lever from P (Park) to N (Neutral). 3. Release the brake and start the car's engine. 4. Press the brake pedal with your foot, shift the gear lever from N to D (Drive), release the brake, and press the accelerator to start moving.
When a car fails to start, I always listen for sounds to diagnose the issue. If the dashboard lights go out during ignition with no cranking sound, it's definitely a battery problem—possibly loose terminals or a completely dead battery. If there's a clicking sound but the engine doesn't turn over, it's usually a stuck starter motor. If you hear the engine cranking but it won't fire, consider fuel pump, spark plugs, or the fuel delivery system. Last week, my car stalled at -15°C—I initially thought it was an aging battery, but it turned out the fuel tank had wax buildup. First, try jump-starting or replacing the battery. If fuel system issues are suspected, check the fuel pump fuse. If that doesn’t work, test cylinder compression—and never overlook hidden faults like a faulty crankshaft position sensor.
I usually follow a three-step approach for starting failure troubleshooting: First, check the power supply—see if the headlights are at normal brightness, and test the battery voltage to ensure it's at least 12.6 volts. Second, listen to the starter—place a screwdriver against the starter motor housing during ignition; weak vibrations indicate worn motor brushes. Third, inspect fuel and ignition—remove the spark plug to check if the electrode is wet with a fuel smell, and loose ignition coil connectors are also common. Once during a camping trip, I encountered starting difficulties and eventually found the anti-theft system had mistakenly locked the fuel injector. The most practical tip is to keep an OBD scanner handy—reading fault codes is far better than guessing blindly.
As someone who frequently drives long distances, I always keep jumper cables in the trunk. Last time at a service area, the car wouldn't start due to oxidized battery terminals, which was fixed by sanding them down. When facing a failed start, avoid repeatedly turning the key—first check the dashboard icons: a flashing battery light indicates an alternator issue, while an engine light may point to a crankshaft sensor fault. Diesel vehicle owners should pay special attention to glow plugs; below -10°C, always wait for the preheat light to go off before starting. Once, I drained the battery by forgetting to turn off the dashcam, so now I regularly check battery health.
