PURPOSE: To carry out a control surely considering a machine difference dispersion at the electronic source throw in time.

CONSTITUTION: A pump mounting side control equipment 4 is mounted in a fuel injection pump 1 for supplying a fuel to an engine, which has EEPROM 6 memorizing the data of machine difference at every fuel injection pump. The data of EEPROM 6 is made to a block at every action order of an engine and also the order of a priority given more priority is attached thereto as it is carried out more early as the action of an engine. A pump non-mounting side control equipment 5 has CPU 9 for driving a fuel injection pump 1 in compliance with the engine running state by the data memorized on EEPROM 6. A serial communication interface 7 transfers the data memorized in EEPROM 6 to the pump non-mounting side control equipment 5 side by the serial communication. CPU 9 sends the data of EEPROM 6 in the order of a high priority, following to an electric source throw in from the pump mounting side control equipment 4 to the pump non-mounting side control equipment 5.
