The CP3 injection pump sits in the valley of the engine between the cylinder heads and is driven by the camshaft gear, and it has two main jobs: get fuel from the tank up to the engine, and pressurize the fuel to 26,000psi and ultimately inject it into the engine.

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.

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.
How to check the fuel pump in a GMC 6.5L?
You can check the fuel pump itself by placing the transmission in drive, and turning the key to ‘start.’ This will not engage the starter, but will engage the fuel pump. You should be able to hear it. Then go ahead and start the engine and place your hand on the fuel pump…you should be able to feel it operating.
Why is the lift pump not working on my GMC 6.5L diesel?
Another problem associated with the OPS is that the lift pump is supposed to send fuel through the IP and back to the tank, helping to cool the IP and the FSD= fuel solenoid driver, the little black box mounted on the driver’s side of the IP. This is basically the brain of the electronic IP.
