For 94 to 98 Dodges, the 5.9L-powered Rams got an inline injection pump (P-pump) thats become the diesel performance equivalent of the Holley 4bbl carburetor. Stricter emissions laws brought about a solenoid-controlled, axial-piston, distributor-style pump (VP44 rotary) for 9812 to 02 models, which suffers (perhaps unfairly) from a reputation for low-performance and poor durability. The 03-and-later trucks got a common-rail injection pump (CP3), which represented a huge breakthrough for Cummins. The following is our rundown of the four different injection systems Dodge used on its Cummins engines. It uses a vane-type supply pump to generate an internal pump pressure that increases with engine speed. It has a single pumping plunger, called a distributor plunger. This plunging and rotating shaft generates injection pressure and controls injection timing. Six individual delivery valves, located in the pump body, connect the pump to the injectors. As the pumps camshaft rotates, the cam lobes drive the six pumping plungers up and down in their barrels. These six individual plungers provide the injection pressure, while the pumps camshaft dictates the firing order. Like the VE, the VP44 uses a vane pump to supply fuel to its internals, but instead of a single pumping plunger, it has three. A high-pressure solenoid valve opens and closes the pumps element chamber to control fuel metering independently of engine speed. The VP44 pump has a built-in ECU that monitors its operation and adjusts engine fueling. The VP44 requires an electric lift pump to feed it diesel from the fuel tank. A common problem associated with the VP44 pump has nothing to do with the pump at all, but rather its lift pump. It is essential that the VP44 gets enough fuel supplied to it-or it will fail. Since the CP3 pumps only job is to create fuel pressure, its not necessary for it to be timed with the engines crank and camshaft position. The CP3 pump is the only Cummins injection pump Dodge has offered that does not control injection timing or fuel quantity directly. ![]()
