Disclosed is an electric control uniset fuel injection pump for a diesel engine. According to the electric control uniset fuel injection pump for the diesel engine, a pump body plunger cavity is communicated with a high-pressure oil hole, an electromagnetic installation hole and a low-pressure oil supply cavity are formed in the two lateral sides, are communicated through a middle connection hole and are perpendicularly communicated with the high-pressure oil hole, the front section of a plunger is assembled in a plunger cavity, the rear section of the plunger is sleeved with a plunger spring and connected with a lower spring base which is embedded in a push rod body, an armature is movably installed in an armature hole of an electromagnet in a sleeved mode, the electromagnet is installed in an electromagnet installation hole, one end of a valve element fixedly installed in the armature hole penetrates through the middle connection hole to extend into the low-pressure oil supply cavity and abut against a lift check block, and the lift check block is connected with an oil inlet pipe. An electric control system is communicated with the electromagnet to control the action of the armature and the valve element, an oil supply system of a traditional fuel injection pump is converted into a fuel injection system featured in time, oil supply timing and quantity are controlled and adjusted precisely, the pressure of the end of the pump is high, oil consumption is low, and noise is low.
