Why is the BYD G6 not responding when starting?
2 Answers
BYD G6 not responding when starting could be due to a damaged battery, abnormal air-fuel mixture ratio, or unstable power supply voltage in the ignition system. The specific reasons are as follows: 1. Damaged battery: If this is the cause, it is difficult for the owner to detect it themselves, and it needs to be sent to a repair shop for professional computer testing. Additionally, it could be due to a depleted battery. If you often drive at low speeds in the city with headlights, air conditioning, audio, and other devices frequently turned on, the battery consumption is relatively high, which may lead to depletion. It is recommended to drive on the highway to fully charge the battery. 2. Abnormal air-fuel mixture ratio: This is the most common and typical reason. In this case, the engine starts normally but fails to ignite. This phenomenon occurs when the throttle valve, intake valve, or idle motor is too dirty. If the valves are too dirty, gasoline will be sprayed onto the back of the valves and absorbed by carbon deposits, preventing the car from starting. Cleaning these components can solve the problem. 3. Unstable power supply voltage in the ignition system: During winter, the engine's starting resistance increases, including insufficient battery power, leading to inadequate voltage in the entire ignition system. Additionally, many owners report that after starting, if they do not continue to press the accelerator, the car immediately stalls. This is caused by a dirty motor or fuel injector. You can slightly increase the throttle, or if that doesn't work, send it to a repair shop for thorough cleaning.
I've been driving a BYD G6 for two years, and the most common issue when it doesn't start is usually the battery. If the battery is old or dead, there's no sound at all when you try to start the car, and the dashboard might flicker before going dark. Check if the battery terminals are loose—tighten them and try again. Or, the key fob battery might be dead. The G6 uses a smart key, and if the signal is weak, the car won't respond. Just replace the key fob battery. Another possibility is a blown starter fuse—look for the relevant fuse in the fuse box under the steering wheel and replace it. If none of these are the issue, it could be a faulty starter motor or poor wiring contact. Try jump-starting the car first; if that works, it's definitely the battery. Remember, a car battery typically lasts about two years—don't skimp on replacing it when needed to avoid getting stranded on the road.
