PROBLEM TO BE SOLVED: To provide a fuel injection control device furnished with an ECU for LPG to calcurate timing of a fuel injection signal of an engine for fuel gas from an injection signal for gasoline from an ECU for gasoline and capable of injecting fuel in starting the engine, in resetting from fuel-cut, in suddenly changing fuel injection quantity and in abnormality of a fuel injection signal conductor for gasoline. SOLUTION: This fuel injection control device is devised to make the ECU 30 for LPG to which the fuel injection signal TAU for the gasoline engine from the ECU 20 for gasoline is input calcurate timing of OFF of the gas fuel injection signal TAUg by computing a crank angle from OFF timing of a plurality of gasoline fuel injection signals and to make ON/OFF timing of the fuel gas injection signal synchronous with the liquid fuel injection signal when it is impossible to compute the crank angle immediately after starting the engine or immediately after resetting a prescribed cylinder from fuel injection-cut.
