A programmable computer controlled electric oil pump drive for engines includes an electric motor, coupler assembly, programmable controller, and mounting plate. A motor drive shaft of the electric motor is coupled to the pump drive shaft of the oil pump through the coupler assembly. The rotation of the electric motor is controlled by the programmable controller. The programmable controller is powered by an engine alternator. The programmable controller also receives a speed signal from a source in the engine electrical system. The programmable controller preferably supplies the electric motor with voltage according to a look-up table or an algorithm. The speed of the oil pump is adjusted according to the engine speed as defined by the look-up table or the algorithm. The speed of the electric motor may be monitored by the programmable controller. If the motor is not rotating or speed of motor is too slow, an audible alarm is provided. The programmable computer controlled electric oil pump drive for engines may be combined with an oil pump, an oil reservoir and connecting device for oil injection of non-oil injected engines.
