A fuel injection control system for an internal combustion engine calculates an amount of fuel to be supplied to the engine, based on operating conditions of the engine including at least load on the engine. The system also calculates an amount of fuel adhering to the inner wall surface of the intake passage of the engine, and an amount of fuel to be carried-off from fuel adhering to the inner wall surface, by the use of adhering fuel parameters representative of transfer characteristics of fuel injected into the intake passage. The amount of fuel to be supplied to the engine is corrected according to the amount of fuel adhering to the inner wall surface of the intake passage and the amount of fuel to be carried-off from fuel adhering to the inner wall surface, to thereby calculate a corrected fuel injection amount. A time period elapsed after the engine is started is measured, and an after-start correction amount of the corrected fuel injection amount is calculated according to the time period elapsed after the engine is started. The corrected fuel injection amount is calculated based on the after-start correction amount of the corrected fuel injection amount until the time period elapsed after the engine is started reaches a predetermined time period.
