A better way (IMO) to test the switch: disconnect the wires to the pressure switch, and connect your ohmmeter to the pressure switch terminals. Call for heat. You should see an open circuit before the call, and a closed circuit after. This way you are actually testing the pressure switch. I'd do this before and after I cleaned out the inducer port.

I’m pretty sure you want the pressure switch to be normally open…
