Not sure if it means anything, but when I switch the key to "run" you hear the pump running stout as ever. I even waited a moment after the pump had been running, in case it was the valve that leaks fuel pressure out of the rail... didn't affect it at all...

Anthony -- My car isn't idling high... it's stumbling as if it's not getting enough fuel/spark. Of course, now it won't run at all.
