1. Transmission Problems: If the transmission is damaged or not engaging properly, it will prevent the car from moving forward or backward. This could be due to issues with the transmission fluid, a faulty transmission control module, or mechanical problems within the transmission itself.
2. Driveline Issues: Problems with the driveshaft, axles, or differential can also cause the car to start but not drive. If any of these components are damaged or not functioning correctly, the power from the engine will not be transmitted to the wheels.
3. Clutch Issues (For manual transmission vehicles): If the clutch is not engaging or disengaging properly, it will prevent the car from moving. This could be due to a faulty clutch cable, a worn clutch disc, or problems with the clutch hydraulics.
4. Brakes Locked Up: If the brakes are stuck in a locked position, the car will be unable to move. This could be caused by a mechanical issue with the brake calipers or rotors, or by a problem with the brake fluid or master cylinder.
5. Electrical Problems: In some cases, electrical issues can also prevent the car from driving. This could include problems with the starter, ignition system, or electrical connections. A malfunctioning speed sensor or faulty wiring could also cause the car to start but not drive.
6. Parking Brake Engaged: Make sure the parking brake is fully disengaged. A car will not move if the parking brake is still partially engaged.
It is important to have the vehicle inspected by a qualified mechanic to pinpoint the exact cause of the problem and get the appropriate repairs done.
