Stock Reman VP44028 Fuel Injection Pump For 2000 - 2002 Dodge Cummins HO (6 speed Manual Trans)
Reman VP44028 Fuel Injection Pump
Dodge 5.9 L VP44 Electronic Fuel Injection Pump
When replacing the Injection pump on a 5.9L 24 valve Dodge truck it is very highly recommended that you also replace the feed pump (CAVHFP923) and the fuel filter. These are the two major causes for pump failure. Failure to replace feed pump along with the Injection Pump may result in non warranted damage. It is highly recommended that the feed pump be changed along with the injection pump. Also an early warning sensor can help prevent pump failure. (1081130)
Performance chip & add on disclaimer
Tampering with the pump's wires can cause premature pump failure. If the wires are cut the pump is no longer warrantable, and any repairs that need to be made to the injection pump will be the buyer's responsibility. In the VP44 pump the fuel is used to cool and lubricate the pump, and the tolerances between the head and the rotor is very fine. Performance chip add-ons affect the cooling rate of the pump. The pump will become hotter due to excessive RPMs from the chips programming. When the throttle is backed off the fuel to the pump is reduced, and the pump's cooling capabilities are greatly reduced. Since the pump is hotter from the increased RPMs the rotor siezes in the head and the pump fails. An alternative to cutting into the pump's wires is to use a chip that plugs directly into the trucks ECM. This approach will allow for an increase in HP while not excessively heating the fuel pump. A great example of this is the DiabloSport Power Puck.
Defective VP44 Engine Codes
Tampering with the the retrieval of codes does not constitute an engine diagnosis. However, there are some codes that usually indicate a defective injection pump. A current P1688 always means that the pump is bad, there is no further diagnosis required. Code P0216 is probably the most common code for VP-44 Pumps. If transfer pump pressure has been checked and is O.K., the injection pump is defective. Other codes that are less common are P0180, P0181, P0215, P0251, P0252, P0253, P0254, P0370, P1287, P1689 and P1690. These codes USUALLY, but not always indicate a defective pump. There are wiring and power checks to be performed if these codes are present. These codes relate to Dodge pickups only, and are not for any other ISB application.
Find the Engine Serial # on Cummins ISB 24 Valve 5.9L Engines
The Engine Serial number is on the engine data plate, which can be found on the drivers side of the timing gear case (see below picture). The plate shows the CPL (control parts list) number, date of manufacture, timing specs, & the engine serial number. To insure that you receive the correct pump please type the Serial Number of your engine in the comments while placing your order. Before we process the order we will cross-reference your engine serial number to the correct vp44 fuel injection pump.
