While on the fuel pump topic, I would add, make sure the ground wires at no 1 intake are tightly connected. It would probably not be an intermittent symptom but still. My car started to stumble and finally just stop after I adjusted the valves. I could not hear the fuel pump as described above. The whining sound was gone. Turns out I had disconnected this ground wire for better access on left intakes and screwed it back on too loose. Took me two hours to find out and 10 seconds to fix.
