A low pressure fuel pump controlling method for a fuel feeding system of a GDI engine that includes a low pressure system and a high pressure system including controlling the low pressure fuel pump against various problems that may occur during the driving of the engine by variable control of the low pressure fuel pump of the low pressure system for the improvement of fuel efficiency of a vehicle. In various situations, the method drives the low pressure fuel pump under a relatively higher pressure than the fuel efficiency pressure.
