A method for assigning addresses to injectors of an internal combustion machine, wherein, prior to the starting procedure, an electronic motor control device selects a first injector by activating the first injector by a first control line from the electronic motor control device. The electronic motor control device is arranged on a data bus to which the electronic motor control device and all injectors are connected. A first address value is placed on the motor control device and the first injector assumes the first address value as the address assigned to it.
