PROBLEM TO BE SOLVED: To provide a fuel control method of an LPI (liquefied petroleum gas injection) engine for calculating an initial fuel supply quantity by taking into consideration fuel remaining in an injector when starting the engine. SOLUTION: This fuel control method is characterized by comprising a stage S20 of sensing the temperature and pressure inside of the injector via a temperature and pressure sensor arranged in the injector, a stage S30 of calculating residual fuel inside of the injector by the temperature and the pressure sensed by the injector, a stage S40 of determining the existence of driving of the engine, a stage S50 of calculating a basic injection quantity of the fuel by taking into consideration the air volume and the temperature of cooling water when driving the engine, and a stage S60 of calculating an initial fuel injection quantity by subtracting a residual fuel quantity inside of the injector from the basic injection quantity.
