What engine did the 1998 Dodge Ram have?

In 1998, a revised version of the 2nd Gen Cummins was introduced. It retained the same body style, but big mechanical changes were made. The new 5.9L Cummins engine had 24 valves, or 4 valves per cylinder. The mechanical “P-Pump formally known as the Bosch P7100 fuel injection pump was replaced with a rotary electric VP44 injection pump. This injection pump is one of the most common 2nd Generation Cummins problems. Other 2nd Gen Cummins specs were changed as well, that helped Dodge trucks stay slightly above their competitors. 1998 Dodge Ram trucks with the 24 valve 5.9L Dodge Cummins engine produce 235 horsepower and 460 lb-ft of torque when paired with the 5-Speed Manual transmission. Trucks from 1998 with automatic transmissions make 215 horsepower and 420 lb-ft of torque.

What is VP44 injection pump?

The change to an electric rotary injection pump was a big step for Cummins. The VP44 injection pump works with the ECU to control fuel injection timing and fuel flow. An electric lift pump was introduced to help keep fuel pressure constant. This lift pump is actually one of the most common reasons the VP44 pump fails. If it doesn’t get the proper fuel supply it’s very likely to break. Aftermarket lift pumps like an Air Dog or Fass system is highly recommended! Despite moving to an electric rotary fuel injection pump, mechanical injectors are still used on late second generation Dodge Cummins trucks. They were re-located however which makes servicing them easier, as well as improves the spray pattern for a better combustion sequence.

What is the Bosch P7100?

The Bosch P7100 mechanical injection pump is without a doubt the most important component of this fuel system though. The “P-Pump” injection pump provides better fueling and can be upgraded for even higher flow and performance. The P-Pump doesn’t do it all by itself though. Injectors were added that were built to sustain the higher fuel pressures. The piston fuel-bowl design was changed to provide better swirl and improve overall combustion quality.
