Control pressure testing - STUPID Queston #1

Ok, I've got the gauge and I've read all the instructions, plus those in my shop manual and other locations, but for the life of me I've got a mental block on one simple part of testing the primary and control pressures:

The obvious: The fuel pumps must run in order to get any readings.
The not so obvious: After installing the gauge, do you run the engine or just run the fuel pumps?
The fear: Won't running the fuel pumps (without the engine running) just dump a bunch of raw fuel through the injectors and into the cylinders? Not a good thing.

So, how about just a little tutorial from someone who has done this himself?
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
