What's the reason when the car won't start?

Here are the reasons why the car won't start: 1. First, check the spark plugs. Since spark plugs are crucial to the car's ignition system, and the ignition system is key to the engine's operation, the performance of the spark plugs directly affects the overall working performance and efficiency of the vehicle. 2. Battery depletion – The symptoms include the starter motor turning but not fast enough (lacking power), and eventually, the starter motor only makes a clicking sound without turning. Low temperatures in winter or forgetting to turn off certain electrical devices can prevent the car from starting, especially when the vehicle is used for short, low-speed trips over a long period in winter, causing the battery voltage to drop below the rated value. If this happens, call the service station for assistance, jump-start the car, or temporarily start it, and then make sure to recharge the battery at the service station. 3. Fuel flow blockage – The symptom is no oil pressure in the engine's fuel supply line. This situation often occurs on extremely cold mornings due to long-term dirt buildup in the fuel lines. When temperatures are extremely low, water and debris mix and block the fuel lines, preventing the car from starting. Emergency solutions: Move the car to a warmer environment, and it should start after a while; or thoroughly clean the fuel lines to resolve the issue.

I just went through this! The most common reason a car won't start is a dead battery. Last time I left the parking lights on for two days and the car wouldn't start. Next is the starter motor issue - if you hear a clicking sound when turning the key but the engine won't fire up, it's probably worn-out starter motor brushes. Also check the fuel system - a faulty fuel pump or clogged injectors can prevent the engine from getting fuel. A less common issue is a faulty crankshaft position sensor - when this fails, the car just plays dead. Don't stubbornly try to fix it yourself - most insurance companies offer free jump-start services now, so calling for a jump-start is the safest first step.
