Reasons Why a Car Won't Start
2 Answers
Reasons why a car won't start are as follows: 1. Battery 'cell break' fault: During startup, only the electromagnetic switch of the starter makes a 'clicking' sound, or the first startup attempt results in the starter slowly turning the crankshaft a few times, followed by the electromagnetic switch making a 'clicking' sound again but the crankshaft does not rotate. 2. Starter relay sticking: During startup, there is only a slight 'click' sound with no further response. In this case, pressing the tail end of the electromagnet to force it forward can connect the startup circuit, thereby starting the engine. 3. Main circuit not connected by the power switch: When the ignition switch is turned to the start position, the engine does not start, and there are no other symptoms.
I've encountered the issue of a car not starting several times, and there can be many reasons. The most common one is battery problems, such as aging or insufficient charge, possibly caused by forgetting to turn off the headlights. Next is a starter failure, where you only hear a buzzing sound when turning the key but no response. Severe carbon buildup on the spark plugs or clogged fuel lines, as well as a malfunctioning fuel pump, can also cause this. Additionally, during cold starts in winter, thick engine oil can make the engine harder to turn. Check if the fuses are blown or if there's poor wiring contact causing a short circuit. Once the car won't start, prioritize checking the battery voltage—if it's below 12 volts, it needs charging or replacement. Regularly avoid prolonged idling and clean engine components to reduce such troubles. If all else fails, call for a jump-start or have it towed to a repair shop—don't push through to avoid further delays.
