What are the reasons why the BYD G5 won't start?
2 Answers
The reasons why the BYD G5 won't start are as follows: 1. The battery is dead or the fuel tank is empty; 2. The gear is not in the correct position or the steering wheel is locked, preventing startup; 3. Automotive circuit or electronic failure, such as damaged spark plugs, blown fuses, or fuel pump malfunction. 4. Fuel quality issues, where poor-quality fuel causes the engine to malfunction. Additional information: 1. Human operational reasons: dead battery, empty fuel tank, incorrect gear position; 2. Vehicle usage reasons: improper fuel, lack of antifreeze, excessive carbon buildup. A dead battery may result from leaving the headlights on for an extended period or the battery reaching the end of its lifespan. Installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit failures.
I remember my BYD G5 also had trouble starting once, during winter when the battery kept dying. I suspect it was due to frequent short trips that didn’t allow the battery to charge sufficiently, or the battery itself was aging—after a few years, it’s time for a replacement. When checking, observe if the lights turn on or if the dashboard responds. If there’s no reaction at all, it’s definitely a battery issue. Quickly use a multimeter to test the voltage; if it’s below 12V, replace it immediately. Another common cause is a stuck starter motor or burnt-out coils—turning the key only produces a clicking sound without the engine cranking. Additionally, ignition system problems like carbon buildup on spark plugs or clogged fuel pump filters can cause trouble, especially after prolonged lack of maintenance. To prevent this, make a habit of turning off lights when parked and regularly check battery health. If the car won’t start, avoid forcing it—try a jump-start or take it straight for repairs to avoid turning minor issues into costly headaches and travel delays. The BYD G5 is a traditional fuel-powered car, and these issues are quite common. Developing good maintenance habits can save a lot of money in the long run.
