Fuel Pump, FP Relay, Fuel System Relay, and what else? 850

I have been battling a fuel problem for several days now. You are welcome to read my earlier posts; however, I think I have narrowed it down to the pump or related devices. When I turn the key, I get no gas from the pump side of the fuel filter. I checked the voltage with the key on position II and get about 12V for a second or two and then nothing. When the car is cranked, the voltage jumps all over the place.

I unplugged the pump altogether and get the same results in position II. My helper went to watch TV so I couldn't crank it. I am currently charging the battery as it is very low from cranking and will try again tomorrow.

Is the 1-2 second 12V normal, or should it stay on 12V constant? If not normal, would this more likely be the fuel pump or fuel system relay. I don't have a parts store locally that can get any of these parts, so I would rather narrow it down before ordering. Also, am I missing any other possibility such as the fuel pressure regulator? Thanks very much for the help.
