What Are the Reasons for a Car Suddenly Failing to Start?

[OFinn]

Reasons for a car suddenly failing to start: 1. The car is out of fuel; 2. The gear is not set correctly. For automatic transmission cars, the gear should be in P (Park) or N (Neutral) when starting. If it is in R (Reverse) or D (Drive), the car will not start; 3. The steering wheel is locked. If the steering wheel is not straightened when parking and is at a slightly larger angle, the steering wheel will automatically lock. At this time, the key cannot be turned, and the car cannot start. To unlock the steering wheel, turn the key while forcefully turning the steering wheel; 4. The fuel filter is clogged. A partially or fully clogged fuel filter can cause insufficient fuel supply, leading to poor fuel return, excessive fuel system pressure, an overly rich air-fuel mixture, and result in the car failing to start or experiencing jerking while driving.
