The battery is dead or contains too much carbon.

1, Futian Yuling 465 car engine can't start, the EFI lamp doesn't work, maybe the battery is dead, so you can go to the 4s shop and let a professional charge it.

2. The engine of Futian Yuling 465 car can't start, and the EFI lamp doesn't light up, which may be because there is too much carbon deposit. Too much carbon deposit will lead to poor ignition of spark plug, lax valve and poor fuel nozzle, which will lead to misfire. Too much carbon deposition in the throttle will also lead to air circulation, and there will be no fire without air coming in. You can go to the 4s shop for repair.
