True enough. But by pulling the plug from the switch that's activated when the arm moves, you're affectively doing the same thing as pushing down on the adjuster screw. Pull the plug or push the arm and the pumps should run. I tried both, to no avail. I'm thinking it's the overboost sensor at the back of the boost recirc valve. Will find out this afternoon when I pull that wire and ground it. The remaining question is....if grounding that wire doesn't work, then does it narrow it down to the OB relay (the yellow one, in my instance)? And if so, I'll try substituting a round relay from the front fuse compartment.
Or bridging between pins 30 and 87A of the relay socket (can someone confirm that those two bridge points are correct???)
