I'm not sure if you have tbi or the spider fuel system? At the pump connector, engine cranking, the gray wire is voltage for the pump, black is ground. If you have good voltage and ground with no pump action, I suspect the pump. I've never had any luck with a no load bench test on a fuel pump. Even bad pumps can run without a load on it, I've seen it.
