Boy I missed a lot of type O's on my last post.I guess the next step is to remove the pump and test it,
if you are fairly sure you have both the power and the ground at the fuel pump and you can not feel or hear it running then its probably not operating.
Before removing it you could remove the fuel line from the cold start valve. put the line is a plastic bottle and crank the engine. If no fuel in the bottle ( having done all your other tests) pump is not operating Yes remove it and test it off the car.
