Why won't the Corolla start?

[SanJohn]

The reasons why a Corolla won't start are: 1. The car is out of fuel. It's necessary to check the vehicle's fuel level, and replenish immediately if insufficient to prevent starting failure due to lack of fuel; 2. The car battery is dead. Improper use of onboard electronics or forgetting to turn off headlights after nighttime driving can drain the battery, resulting in failure to start the car; 3. Severe carbon buildup in the engine. Irregular vehicle maintenance can lead to serious carbon deposits that affect vehicle performance, sometimes causing shaking or vibration during idle; 4. Exhaust pipe blockage. A broken catalytic converter causing exhaust obstruction or external forces deforming the exhaust pipe can prevent the car from starting.
