Does a common rail injector pump need to be timed?
Unlike mechanical systems these high pressure type pumps do not need to be timed with the engine as the injections timing is controlled by the ECM firing the injectors, and the pressure control valve is controlled by the ECU and varies rail pressure according to load demand.
Where is the fuel injection pump located?
In petrol engines, the fuel pump is usually located inside the fuel tank. In diesel engines, the fuel tank holds an auxiliary pump, while the injection pump, generating high pressure and controlling the order in which the injectors are opened, is located next to the engine.
What is the CP3 on a 5.9 Cummins?

How do I test my injection pump?
The inj pump does all the really hard work of delivering the fuel to the cylinders via the injectors. To test the lift pump, once the engine is running, open the bleeder at the fuel filter. The engine should stay running and the fuel should really squirt out.
What pressure does a common rail diesel run at?
2,000 BAR – 29,000 PSI
Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines. On diesel engines, it features a high-pressure (2,000 BAR – 29,000 PSI) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles.
How do I know if my injection timing is correct?
You can check the injection timing by measuring the injector pump’s stroke at TDC using a dial indicator.
What year of Cummins had CP3?
GM was the first to use the CP3 in a pickup application with the LB7 Duramax in 2001, and just two years later in ’03, the Cummins engine in Dodge Rams also started using the Bosch pump, with the only functional difference being Dodge also utilized a lift pump in the tank, where GM relied on the gerotor pump built into …
Does a 2003 Cummins have a lift pump?
The factory fuel system on your 2003-04 5.9L Dodge Cummins consists of your underbed fuel tank, fuel/lift pump, high pressure CP3 injection pump, and electronically controlled injectors (simplistically put).
What causes injector pumps to fail?
A major cause for fuel injection pump problems is the use of dirty fuel. Over time, residue builds up throughout your system. Using poor-quality fuel exacerbates this issue. Bring your vehicle in for auto repair if you notice sputtering or your vehicle hesitates when accelerating.
How do you test a diesel in common rail injectors?
How to perform a common rail injector function test
- MOUNT THE INJECTOR. First lift the protective door and place the injector in the universal mount.
- CONNECT BACK-LEAK PIPE AND COMPLETE SETUP. If you’re using the optional back-leak measurement unit, connect it now.
- TEST THE INJECTOR.
- RECORD AND ANALYSE.
What causes common rail failure?
There are a several things that can cause failures in common rail injectors and some of those are; Ball seat erosion. Nozzle erosion. Solenoid coil winding shorting.
Can you clean common rail injectors?
If the fuel injectors have deposits, it’s important to clean them to restore engine performance back to the way it was. At a professional garage, they may use an ultrasonic machine to clean the injectors out.
