What are the reasons why a car won't start after parking and stalling?

There are several reasons why a car won't start after parking and stalling: 1. Battery depletion: When the car battery is depleted, the car may not start after parking and stalling. There are many reasons for car battery depletion, such as lack of water in the battery, battery failure, or prolonged use of the air conditioning. 2. Low temperature: In cold winter weather, cars often fail to start after parking and stalling. This is because in low-temperature environments, the viscosity and rotation speed of the car's engine oil decrease, leading to reduced ignition energy in the battery and decreased molecular activity, making it difficult to form flammable gases. 3. Carbon buildup in the car: Carbon buildup in the car's engine can cause many problems, the most common being the car not starting after parking and stalling. There are many reasons for engine carbon buildup, such as excessive moisture in gasoline, poor fuel quality, and poor sealing of the valve seat ring.
I've encountered several instances where the car wouldn't start after stalling. The most common issue is a dead battery, especially in older cars that are three or four years old. Sometimes, it's because I forgot to turn off the music or lights while parked, and when I tried to start the car again, the battery was completely drained. Once, I had a problem with poor contact in the ignition switch—when I turned the key, it made a clicking sound but the engine wouldn't start. A faulty fuel pump is also a typical issue; even though there's fuel in the tank, the engine just revs without starting. There are also less common problems like a broken crankshaft position sensor or a generator failure that drains the battery before the car stalls. Now, I always carry jumper cables in my car so I can get a jump start from a nearby vehicle if the battery dies.
