What is the problem when a manual transmission car stalls while shifting into reverse gear?

It is caused by incomplete clutch disengagement. If it is an automatic transmission car, you can simply press the brake, shift into reverse gear, and gradually apply the throttle. For a manual transmission car, it is more troublesome. You need to start the engine first, then press the clutch and shift into reverse gear. After that, gently release the clutch while slowly applying the throttle to avoid stalling. The reasons for car stalling are as follows: 1. No fuel supply can cause stalling: The cause is mostly related to the fuel pump. A stuck fuel pump or a faulty fuel pump can suddenly stop supplying fuel, leading to stalling. 2. Electrical issues: It could be due to faulty spark plugs or ignition coils, causing one or multiple cylinders to misfire, resulting in stalling. However, stalling is more likely when multiple cylinders fail to ignite simultaneously, so this possibility is relatively low. 3. Control problems: These stem from the engine control unit (ECU). Given the high mileage, the car has been in use for a long time, and the possibility of the ECU malfunctioning is also relatively high.
I remember when I first started driving a manual transmission, stalling while reversing was quite common, mainly because the clutch wasn't fully depressed—the car would shudder and stall as soon as I released the pedal. Beginners often make this mistake; shifting into reverse should be done slowly to allow the gears to fully engage. If the clutch system is worn or the cable is aging, gear shifting won't be smooth. It's also important to check if the idle speed is too low, as insufficient engine RPM can cause stalling. In cold weather, low oil temperature can make the engine run unevenly, so practicing the half-clutch technique is recommended to maintain stability. Regular clutch maintenance can reduce such issues and ensure safe reversing.
