Okay, so there doesn't appear to be any way to hook up a fuel pressure gauge on a Focus? I can't find any test port on the rail (2000 Ztec).
But I did remove the fuel fitting from the rail, turned ignition on: nothing. Cranked over and it started for a bit, I suspect it was able to suck fuel in that was otherwise held back by having had the line sucked dry.
I checked the fuel pressure switch again. Is there any reason that it wouldn't pump fuel just because the alternator is disconnnected? I still just have it running with the timing belt, not the accessory belt.
