My initial search term was "fuel pressure", and when following one of the "fuel pressure regulator" search results, I saw a link that said "fuel system diagnosis". After that I used "fuel system diagnosis" as my search term, and the fuel pressure readings were listed under a few different topics.

Most of the results were in section 6E - Engine\ 6VE1 3.5L Engine Driveability and Emissions.
