Your pump activity sounds normal.
The issue can be one of the injection valves (dirty or a bad diaphragm), a vacuum leak, clogged passages in the head, or a dirty filter or screen.
You aren't operating in a vacuum, either. MB hasn't changed the basics of this system in a long time, so searching that DTC will get you all the information you should need.
Socialism is a philosophy of failure, the creed of ignorance, and the gospel of envy; its inherent virtue is the equal sharing of misery. (Winston Churchill)
