Abstract
An ECU as a fuel injection control device includes: an injector control part that energizes a magnetic circuit of a fuel injector by a specified injection pulse to thereby open the fuel injector and that energizes the magnetic circuit by a specified energization pulse within a range in which a needle valve of the fuel injector is not driven; and a storage part that stores information relating to a behavior of a drive voltage (minus terminal voltage) of the fuel injector when the magnetic circuit is energized by the injector control part by the specified energization pulse.
