What Causes an Engine to Seize and Fail to Start?

[RowanLee]

Here are the reasons why an engine may seize and fail to start: Low Temperature: This situation usually occurs in winter. The viscosity and rotation speed of the car's engine oil decrease, while the battery's ignition energy also drops, making it difficult to form flammable gases and thus hard to start the engine. Faulty Spark Plug: The spark plug is a critical component of the car's ignition system, and the ignition system is key to whether the car's 'heart' works or not. Therefore, whether the spark plug functions properly directly affects the vehicle's performance and efficiency. Emergency Solution: You can unscrew the spark plug, clean it, and reinstall it to start the car. A thorough solution involves inspecting the ignition system to eliminate causes of low ignition energy, such as checking the spark plug electrode gap, ignition coil energy, and the condition of the high-voltage wires.
