As far as the 5.9/6.7 B-series Cummins is concerned:
Until January 1, 1998, mechanical pumps/injectors were used, the last being the Bosch P7100 pump.
From January 1, 1998 through December 1, 2002, the Bosch VP-44 was used. This was a mechanical plunger pump with integrated electronic controls.
From January 1, 2003 onwards, the engines have been high pressure common rail (HPCR) injected with the rail pressurized by an engine-driven CP3 pump. These are electronic engines in that the injectors are fed from the fuel rail but controlled electronically.
