What are the reasons why an automatic car won't start?

There are three main reasons why an automatic car won't start. Here is a detailed introduction to these three reasons: 1. Spark plug failure: When the spark plugs of an automatic car fail, it can easily cause the car to not start. The spark plugs should be replaced promptly. 2. Poor quality antifreeze: Using low-quality antifreeze can easily cause the engine to crack in low temperatures, leading to the car's water pump not functioning and the car not starting. At the same time, it can also damage other parts of the engine. 3. Wrong gear position: When starting an automatic car, the gear must be placed in the P or N position. It will not start if placed in the R or D position. Additionally, some manual cars will not start if the clutch is not pressed.
As a seasoned driver with years of experience, I've encountered several instances where an automatic transmission car wouldn't start, which is quite common. The most frequent cause is a dead battery, such as when low winter temperatures reduce battery performance, or when you forget to turn off the headlights or a charger, draining the battery. First, check if the dashboard lights come on; if they don't, it's likely a battery issue. Another key point is the gear position—automatic cars must be in P or N to start, and sometimes they won't recognize if the wrong gear is selected. Starter motor failure is another possibility, characterized by weak cranking or unusual noises, or a blown relay or fuse. A fuel pump issue could also prevent gasoline from being pumped, and you won't hear the humming sound during startup. It's advisable to regularly monitor battery health during maintenance, carry a portable charger or jumper cables for self-rescue, and if attempts fail, promptly visit a repair shop to avoid delays or potential damage to other components.
