The present device is constituted such that a plunger pump P is constituted by a cylinder 8, a plunger 10, which is slidably mounted within this cylinder to form a pressure chamber 9, and a solenoid coil 11, which drives this plunger; at the lower section of a body 6, which comprises the plunger pump, an intake section 1a, which is linked to the pressure chamber by the operation of the plunger, is provided, and, at the upper section of the body 6, a return section 1b, which returns surplus fuel to a fuel tank 2, is provided; and a circulation passage 14, which guides a portion of the fuel, that branches off from the intake section, toward the return section, is provided between the cylinder and the solenoid coil. Accordingly, it is an object of the present invention to suppress the penetration of vapor into the fuel injection device, and to provide an electronic control fuel injection device that is inexpensive and highly durable. <IMAGE>
