What are the reasons why BYD cannot start?

[VanRafael]

BYD cannot start due to a dead battery or faulty spark plugs. Here are the relevant details: 1. Battery: A battery is a type of cell, also known as a storage battery, which works by converting chemical energy into electrical energy. The battery commonly referred to is a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. 2. Spark Plugs: Spark plugs are crucial components in the ignition system of a gasoline engine. They introduce high-voltage electricity into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. They mainly consist of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell.

Last time my BYD also suddenly wouldn't start, almost making me late for work. The most common issue is a dead battery, possibly from forgetting to turn off the headlights or the car sitting idle too long. If you only hear a clicking sound when turning the key, the starter is likely the problem. It could also be a fuel pump failure - the tank has gas but it's not being delivered. In hot weather, pay attention to the alternator belt too; once my cracked belt caused a complete power failure. For push-button start models, make sure the key fob has enough battery - try moving it closer to the start button. And don't forget simple things like being in Park gear - last time my wife couldn't start the car because it was in the wrong gear.

With over a decade of experience in auto repair, I've seen many BYD starting failures. First, check if the battery terminals are oxidized and sand them down if needed. The ignition system also needs inspection—a faulty crankshaft position sensor can prevent the engine from starting. For hybrid models, pay attention to the auxiliary battery; when it's depleted, the screen won't even light up. A clogged fuel tank charcoal canister can trigger the environmental protection mode, requiring replacement of the activated carbon canister. Vehicles with start-stop systems are prone to burning out the starter due to frequent starts. For older models, inspect the anti-theft module wiring harness—loose connections can lock the engine. It's advisable to keep an OBD scanner handy to check for trouble codes, which saves time compared to guessing.

After twenty years of driving, starting issues boil down to just a few common culprits. A weak battery is the most obvious – you'll notice dim dashboard lights. If the engine oil viscosity is too high, the oil pump struggles during cold starts, especially common in northern winters. The fuel filter needs replacing every 50,000 km – when clogged, it causes insufficient fuel pressure. When the steering wheel locks, the key won't turn; just wiggle it slightly to release. Once had starting trouble after refueling – turned out the station gave me 92 octane by mistake. Excessive spark plug carbon buildup causes poor ignition, with noticeable shaking during acceleration. Before calling a tow truck, try jump-starting first.

Last week, my best friend's car wouldn't start in the mall parking lot, and she was so anxious she started crying. Later, we found out the gear shift wasn't fully pushed back to the P position, and it worked fine after shifting again. Girls often forget to turn off the reading light, draining the battery overnight. Too many perfume bottles in the car spilled onto the electronic parking brake button, causing a short circuit. Some newer models require pressing the brake to start, so remember to use some leg strength. Phone power banks connected to the cigarette lighter can also secretly drain the battery. Humid rainy seasons might cause the ignition coil to get damp, but just drying it in the garage for two days will do the trick. It's safest to keep an emergency power supply in the trunk.

Experienced multiple starting failures while modifying cars. Installed a high-power audio system without adding a capacitor, and the battery drained after listening to music for half an hour while parked. Poor contact in the ground wire circuit can cause a hissing sound, and oxidation leads to leakage. In turbocharged models, a faulty intake pressure sensor can cause the ECU to limit starting to protect the engine. In hybrid cars, not closing the charging port cover tightly can trigger the safety lock. When the remote start function fails, check the signal receiving antenna. False reports from the wheel speed sensor can make the system think the car is moving and refuse to start. Regularly cleaning out rodent nests in the engine bay is crucial, as they love to chew on wires.
