ABSTRACT:
In method and apparatus for controlling starting of a solenoid-operated valve for an internal combustion engine, when a request for a start of the solenoid-operated valve is generated, a provisional target position to which an armature is likely to be moved is determined, and the armature is moved to the determined provisional target position. If the provisional target position is difference from a predetermined target position, the armature is moved to the target position after being moved from the neutral position to the provisional target position.
