Haojue bent beam 1 10-7c EFI refueling?

What if Haojue Curved Beam 1 10-7c EFI can't refuel?

1. Find a quiet place, unplug the key and turn it on, and see if there is any buzzing sound (it won't take long, usually it will ring for a few seconds) to confirm whether the oil pump works normally. 2. Check whether there is pressure in the oil pipe by pulling out the key, then holding the pipe between the throttle valve and the oil tank by hand, and then inserting the key. The pressure of electrospray is generally 2KG, so the pipe feels after being compressed. 3. Check whether the threaded end of ecu is loose, resulting in poor signal transmission. 4. The way to check the cylinder temperature sensor is to take a ride to see if the speed is affected, because the previous EFI system with combined power scheme has the problem of chaotic speed control at high temperature. 5. Check the oxygen sensor for the same reason as above. If the above methods can't be solved, we have to ask them to solve it after sale.
