A fuel delivery control system controls fuel delivery for an engine having a plurality of cylinders and a electronically controlled fuel injection unit for controlling fuel delivered to each cylinder in response to control signals generated by an electronic control unit. The control unit, for each cylinder, determines an engine acceleration value derived from a crank position value generated by an engine crank position sensor, compares the acceleration value to a threshold value, and terminates fuel delivery to only the cylinders for which the comparison indicates unsatisfactory combustion, up to one half of the cylinders. The control unit operates to deliver a normal amount of fuel to cylinders for which the comparison indicates satisfactory combustion, and to cylinders for which fuel delivery has been terminated for a pre-set maximum number of times.
