What should I do if the cold crown block doesn't catch fire?

You can check the spark plug of the car. Replacing the spark plug in time will make the engine easier to start.

The main reason why cars can't start in cold weather is because of the influence of temperature. The lower the outside temperature, the lower the battery capacity, and it will be difficult to catch fire.

The car can't be hit in cold weather, largely because of the antifreeze of the car. Do not use inferior antifreeze or tap water for daily maintenance of automobiles, which may easily lead to engine failure.

Because the outside air temperature is relatively low, at low temperature, the resistance of the battery will increase and the output power of the battery will decrease due to the increase of electrolyte viscosity and the decrease of permeability. In this state, the engine will be difficult to start, and the minimum starting speed will not be reached, which will affect the engine starting.

It should be noted that spark plugs will age after long-term use. If the ignition gap of the spark plug increases, it will make it difficult to start the car. If the spark plug is seriously aging or carbon deposit, it needs to be replaced in time to avoid affecting the normal operation of the engine.

It is worth mentioning that if it is a diesel car, it will not catch fire in winter.
