PURPOSE: A control method of a fuel injection is provided to prevent the unnecessary waste of fuel by controlling the injected amount of fuel according to the temperature of coolant and input air at a restarting of an engine. CONSTITUTION: In turning on a starting switch(S1), a temperature sensor detects a temperature(S2). The stop status of an engine by a very low temperature is checked(S3). Fuel is normally injected by operating the engine when an external environment is not the very low temperature. In turning the starting switch(S1) at the very low temperature, the temperature inside a cylinder is raised and engine oil is injected. However, the engine is stopped because the fuel is not reached to an ignition point. In stopping the engine, a driver tries to restart. The restarting is checked(S4). In restarting, an appropriate fuel amount is calculated through a map of counted stop time after stopping the engine. Thereby, the unnecessary waste of fuel is reduced.
