A fuel injection and ignition control method including the steps of: calculating a total injection amount correction value at the restart of fuel injection by adding an injection amount correction value determined with respect to a fuel cut period and an engine operating state to an injection amount increase correction value in acceleration when an engine accelerating operation is performed in a state where fuel cut is performed and the engine is operated; determining an injection restart time ignition timing delay amount with respect to the total injection amount correction value and a throttle valve opening degree; and performing fuel injection control to increase a fuel injection amount to be higher than a fuel injection amount in normal time by the total injection amount correction value, and ignition control to delay ignition timing from ignition timing in normal operation by the injection restart time ignition timing delay amount.
