Sign 508 stops fuel supply suddenly while driving.

It is common that the car can't refuel when driving, such as poor gasoline quality, oxygen sensor failure, air leakage in the intake pipe leading to too thin mixture, abnormal signal from the throttle position sensor and so on. It is suggested to check whether the steam filter is blocked, whether the pump pressure of the gasoline pump is sufficient, whether the nozzle is blocked, and whether the three-way catalyst and the entire exhaust pipe are blocked. It is best to clean the oil circuit and deal with the carbon deposit in the engine.
