What to Do When a Car Won't Start?

[AutumnAnn]

A car may fail to start due to a dead battery, ignition system failure, or excessively low temperatures. Here is relevant information: 1. Dead Battery: If the power switch has no electricity, the house will experience a blackout. Similarly, when a car's battery is dead, the car won't start. There are many reasons for a dead car battery, such as insufficient battery water, battery malfunction, or prolonged use of the air conditioning. 2. Ignition System Failure: The function of a car's ignition system is to provide high-voltage electricity to the spark plugs at the right time to ensure the car runs normally. If the car won't start and the battery is ruled out, the issue is likely with the car's ignition system. Poor connections in the low-voltage circuit or leakage in the high-voltage wires can cause ignition system failure, affecting the car's ability to start. 3. Excessively Low Temperatures: In cold winter weather, cars often fail to start. This is because, in low-temperature environments, the viscosity of the car's engine oil decreases, leading to reduced ignition energy from the battery and decreased molecular activity. As a result, flammable gases cannot form, making it difficult to start the car.
