A fuel injection pump has a control sleeve slidably fitted over a plunger. The plunger is provided with two lateral holes and an inclined groove open to and extending between respective ends of said lateral holes. The end of injection occurs when the inclined groove communicates with a cut-off port formed in the control sleeve, and the timing of injection is adjustable by the rotation of the plunger. To keep fuel noninjected, the plunger is rotated to a position at which the second lateral hole is brought into communication with the cut-off port.
