A high-pressure fuel pump control device and an in-cylinder injection engine control device are provided in which a high-pressure fuel pump accelerates a rise in fuel pressure from the start-up of an engine thereby to make it possible to shorten an engine start-up time, reduce an exhaust gas substance and improve or increase an engine output, for example. The high-pressure fuel pump control device and in-cylinder injection engine control device control an in-cylinder injection engine having a fuel injection valve provided in a cylinder, a high-pressure fuel pump for force-feeding a fuel to the fuel injection valve, and a crank angle sensor for detecting the position of a crankshaft of the cylinder. The high-pressure fuel pump is provided with a plunger for pressurizing the fuel placed in the high-pressure fuel pump, a pump drive cam for driving the plunger, and a cam angle sensor for detecting the position of the pump drive camp. The high-pressure fuel pump control device and in-cylinder injection engine control device is provided with drive signal setting means for outputting drive signals to the high-pressure fuel pump at least two or more times from the time of signal detection of the crank angle sensor to the time of determination of the phases of the crank angle sensor and the cam angle sensor.
