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. When the engine is in a starting condition, and at the same time the corrected fuel injection amount is below a predetermined value, fuel is injected into the intake passage in an amount at least larger than the predetermined value.
