What is the difference in an injector pump and a high pressure oil pump on a 7.3 powerstroke?

Technically the 7.3L doesn't have a injection pump only a high pressure oil pump. Rule of thumb is that an injection pump delivers fuel to the engine and is a very larger cumbersome unit that's very complicated and houses it's own camshaft, plungers, rack sensor, pre-stroke actuator, and in theory is a small engine in it's self. Due to the fact that the 7.3L design uses high pressure oil to pop off the injectors it is commonly thought to be linked to the fuel system which it is not at all. But is what drives the injectors to inject fuel into the cyl. It's called a HEUI (Hydraulic, Electronic, Unit, Injector) injector and has a very unique way of working. Engine manufacturer Caterpillar was the designer of this style fuel injector and International mirrored it's design almost to the Tee. Even though it's a very complex system the bottom line is that it works and works very well when service is kept up. Hope this helps and clarifies the difference between the two systems.

How do you change injectors on a powerstroke 6.0?
To change the injectors on a 6.0 you must first 1. Remove the valve covers 2. Remove the high pressure oil rail. Be careful not to drop any bolts, not to break off the injector connectors, they break easily. 3. Remove the injector clips on the outside of the head, inboard towards the turbo. 4. unbolt the injector 5. Use an injector puller so that you dont damage the injector, or injector bore.

it is the front top center of engine
What opens the injectors on 99 powerstroke?
They are actuated by hydraulic pressure. An electric solenoid closes a passage that allows high pressure oil to flow through an inlet check valve and back to the sump. When that passage is closed the oil pressure acts on a plunger in the injector and strokes it. When the solenoid is released the oil is vented through the outlet and back to the sump.

you have to remove the high pressure oil manifold, then remove the fuel injector.

What is a saturated fuel injector?
A saturated fuel injector is also known as a High Impedance (or High z) fuel injector. The high z injector has a larger ohm draw through the coil (12v-15v) vs. a peak-hold (Low Impedance, Low z) injector, which is 2v-4v. Another difference is the how the injector uses the voltage to open the injector. A high z injector uses the full voltage to open and hold open the injector, therefore it voltage saturated. A low z injector (peak-hold) has a peak of high voltage to open then injector then uses a lower voltage to keep the injector open for the remainder of it's cycle. What this means to you, the low z injectors typically needs a resistor in line to add the necessary resistance to properly drive the system, otherwise the injectors could overheat to fatigue. A high z injector does not need a resistor.
