What injection pump is in a 2003 Cummins?
Bosch CP3 Common Rail
At the heart of the 2003 – 2007 Dodge 5.9L Cummins is the Bosch CP3 Common Rail diesel fuel injection pump.
How does the CP3 pump work?
The injection pump uses electronics and a Fuel Control Actuator (FCA) to regulate this pressure and increase volume and pressure as requested. Since an engine will need less volume and pressure at idle than it would under a heavy wide-open throttle run, the pressure regulator is key to a proper functioning CP3.
What’s the pressure of a diesel injector pump?
Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch). But that’s only about half of what engines are expected to do today.
Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.
What kind of fuel injector do I need for a 2003 Cummins?
The BD-Power 1725521 Premium Remanufactured Fuel Injector is a direct-fit replacement for your 2003-2004 Dodge 5.9L Cummins. Each Premium Remanufactured Fuel Injector is remanufactured by trained Bosch technicians that are highly skilled.
What happens if the fuel injector doesn’t close?
If the injector can’t close, cylinder performance is compromised. Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.
