What are the reasons why the BYD Song won't start?

Here are the reasons why the BYD Song won't start: 1. No antifreeze added: Some car owners add water to the car or place antifreeze, resulting in the entire waterway being frozen in extremely cold winter conditions, causing the engine to crack, the car's water pump to fail to operate, the car not to start, and damage to other engine components. 2. Excessive carbon buildup: Excessive carbon buildup in the vehicle can also cause the car not to start. In this case, frequently driving at high speeds can reduce carbon buildup. Additionally, there is a small trick for when the car won't start: before turning the key to start the car, first turn it to the ON switch, then back, and then to the START switch to ignite, allowing the computer to calculate the water temperature and the appropriate air intake, making the ignition smoother.
I just encountered a problem with my BYD Song not starting the other day, which was really frustrating. First, check if the battery is low on charge—for example, leaving the lights or electrical devices on after parking can drain the battery, making it hard to start. Insufficient fuel is another common reason; an empty tank naturally won’t ignite. If it’s an ignition system issue, carbon buildup on the spark plugs or a faulty ignition coil can directly affect starting. Also, a dead key fob battery means the car won’t detect it, preventing startup. I recommend using a voltmeter to check if the battery voltage is below 12 volts to rule out simple issues. Regular maintenance is key—periodically check for loose wiring connections and always turn off all lights before parking to develop good habits and reduce trouble. If the car won’t start, don’t panic—try replacing a fuse or calling a professional for diagnosis first.
As someone who often helps friends with car repairs, I've seen many cases of BYD Song failing to start. Loose or corroded battery terminals can cause poor contact and affect power supply. Starter motor failure is also a common issue - if you hear a clicking sound but no response, it might be stuck. Always check if the fuel pump is working; a humming sound at idle could indicate a problem. The electronic control unit (ECU) occasionally malfunctions and may mistakenly prevent startup. Damaged sensors like the crankshaft position sensor are also frequent culprits. It's best to inspect the fuse box and check if the headlight fuse is blown, replacing it promptly without tampering with the circuit. Maintain clean battery terminals daily to avoid leakage, and use a charger overnight when necessary. Addressing these minor issues promptly can save you a lot of trouble.
