PURPOSE: A fuel injection amount is compensated directly by intake pressure variation sensed by an intake pressure sensor which is installed in an intake manifold. CONSTITUTION: In a method for controlling fuel injection in cryogenic starting, it is checked whether freezing water temperature(WT) is below a certain temperature(WTO)(S1). If above condition satisfies, ignition switch is turned on(S2), and cranked(S3). An intake pressure is checked(S4). A fuel compensation rate(FP) by the variation of the intake pressure is output, and the fuel injection amount(FINJ=FT*FP) is decided by compensating basic fuel injection amount(FT)(S5). And whether engine revolution number(N) is over a certain speed(NO) is checked(S6). If the engine revolution number(N) is over the speed(NO), the power supplied to a starter motor is cut(S7).
