Reliability-wise, Murphy's law states that a totally mechanical system will outlast a drive by wire, electrically-controlled unit each and every time. As I said, too many parameters that need an expensive scan tool to diagnose vs. "this is not right, I'll replace it and whaddaya know-it works again". Either way, Cummins has a superior engine and their tragic flaw is that the ISB was years behind the times when it was introduced due to the rotary pump. Ford is about to retire the current T444E and the engine is STILL ahead of its time, despite being a V8. Cummins better get back on track and back into the passing lane with a common rail system in this country.
