PURPOSE: A method of controlling the sprayed fuel amount of a vehicle is provided to prevent sagging, hesitation or stalling of an engine by controlling the sprayed amount of fuel depending on volatility of fuel. CONSTITUTION: An ECM(electronic control module,400) receives signals from a pressure sensor(100) of a fuel tank, a fuel rate sensor(200) and a temperature sensor(300). The ECM sets reference pressure and a permissible error depending on temperature and fuel rate. After that, the ECM controls the spraying amount of fuel larger or smaller than reference one if the difference between the reference pressure and the permissible error is smaller or larger than 0 respectively. That is, the ECM controls the spraying amount of fuel depending on the fuel tank pressure.
