Why can a car start but not move?

[Tamara]

Car can start but not move due to the following reasons: 1. The car's anti-theft system is triggered, causing the engine to lock; 2. Ignition switch failure; 3. Damaged ignition module or damaged ignition reference signal line from the ignition module to the engine computer; 4. Low fuel pump pressure, fuel line leakage, insufficient fuel supply current, or damaged fuel pressure regulator; 5. Carbon deposits in the engine. The solutions are: check if the car's anti-theft system is triggered, inspect the working condition of the ignition switch, check for faults in the ignition module and signal line, examine the fuel lines for leaks, clean engine carbon deposits, and verify if the battery has sufficient power.
