Update: Now that I've finally corrected my vacuum leak (faulty secondary solenoid), I turned the key to "on" with the plenum off, and I sure don't hear the fuel pump running. Hooked up my fuel pressure gauge to the rail and the needle hardly moves -- up to 8-10psi or so -- push the pin of the schrader valve in, and a brief little "hiss" of fuel, then nothing.. not the geyser I would expect. Pump dead/dying? I have a spare pump assembly here....
