My Li Xia 7 10 1A EFI, distributor, high voltage line, cylinder pressure, spark plug, etc. Everything has been checked, but the refueling is not smooth and intermittent. ...

1。 Check the gasoline pump. Don't use too little gasoline in the car. Too little oil has poor heat dissipation and is easy to break down.

2。 You can also check the throttle position sensor, stepper motor (or idle valve) and intake pressure sensor.

3。 Nozzle and throttle valve can be cleaned. If the car is too old, it may be that the accelerator is broken (there is a thermal sensor plug in it, which has not worked well for many years).

Basically all people,

4。 Another place is that there are several safety connectors on one of the battery clips (the positions can be adjusted to see if they are good or bad).

Finally, the relay (N) in the relay box between the battery and the left wheel may also cause the problem that the engine cannot be refueled or shut down.
