Why does the BYD F0 not respond when starting?

The reasons why the BYD F0 does not respond when starting are: 1. The battery is dead; 2. The ignition device or relay is faulty; 3. The gasoline flow is blocked; 4. The ignition system is not working properly. Taking the 2015 BYD F0 as an example, it is a micro car with body dimensions of 3460mm in length, 1618mm in width, and 1465mm in height, a wheelbase of 2340mm, and a body weight of 870kg. The 2015 BYD F0 has a MacPherson independent front suspension and a trailing arm with torsion beam rear suspension. It is equipped with a 1.0T naturally aspirated engine with a maximum horsepower of 68PS, a maximum torque of 90Nm, and a maximum power of 50kW, paired with a 5-speed manual transmission.
As a seasoned driver who's owned three F0s, I always check the battery first when there's no response during ignition. Last time at the market, the dashboard went dark when turning the key - turned out the battery terminals were oxidized white. Sanding the contacts bright immediately got it started. Another time in -10°C winter, my 5-year-old battery completely died, showing no response even to jump-start. In emergencies, tapping the starter motor can help when the motor brushes get stuck. Also, a locked steering wheel can block ignition - try wiggling the wheel while turning the key. The F0's ignition switch tends to have poor contact; removing and reinserting the key a few times might work.
The repair shop next door often deals with F0 issues, and I often drop by to chat and pick up a few tricks. If the horn doesn't sound, it's usually due to a dead battery—borrowing a jump starter is the easiest fix. If the horn works but the starter doesn't turn, crawl under the car and check the starter motor wiring harness connector; last year's heavy rains caused many cases of rusted and broken connections. Listen for a clicking sound when starting—if you hear it, the starter solenoid is likely faulty. For those who've installed aftermarket anti-theft devices, be extra cautious; once, they had to remove an Ironclad anti-theft box to get the car started. It's best to keep an OBD scanner handy to read trouble codes.
