What to Do When the Car Won't Start After Sitting for a Long Time?

[McNatalie]

Before starting the car, turn the key to the ON position, then back to the START position to ignite, allowing the computer to calculate the water temperature and appropriate air intake, which should help start the engine. Below are specific reasons why a car may not start after being parked for an extended period: 1. Fuel quality issues: Poor fuel quality can prevent the car from starting. Always refuel at reputable gas stations, and when traveling, you can use a gauze over the fuel nozzle to filter out impurities. 2. Insufficient or low-quality antifreeze: Not using antifreeze, adding water, or using low-quality antifreeze can cause the entire cooling system to freeze in extremely cold weather, leading to a cracked engine, inoperable water pump, and failure to start, potentially damaging the engine and other components. 3. Excessive carbon buildup: Too much carbon buildup can also prevent the car from starting. The solution is to frequently drive at high speeds, which can effectively reduce carbon deposits.
