Why doesn't the car move when pressing the accelerator?

[DelSawyer]

The reasons why a car cannot move when pressing the accelerator should be determined based on specific conditions, as follows: If the accelerator is pressed, the tachometer shows an increase in engine speed, but the car cannot continue moving, it indicates a clutch failure. The clutch needs to be inspected to determine whether its working condition is normal. If the accelerator is pressed, the tachometer shows no change in speed, and the car does not move, it means the car is not injecting fuel. This could be due to issues with the fuel supply system or the accelerator cable. The fuel supply system and accelerator cable should be checked promptly, and the fuel supply system may also need appropriate cleaning. If black smoke appears when pressing the accelerator, but the car does not move, it indicates a fault in the ignition system. The car's ignition should be checked to see if it is functioning properly. The power source of a car is mainly provided by the combination of the intake system, fuel supply system, related electronic circuits, and electronic components. Therefore, when the car cannot move despite pressing the accelerator, these parts should be inspected in detail to see if they are affecting the car's movement.
