Do you have a diagram for the fuel pump circuit?
If you are on the correct wire, and your checking available voltage to the pump, make sure you are doing it with the fuel pump in its running position, or the reading won't be accurate. In other words when you check voltage there, kick the key over (when it primes the fuel system) and then check your reading.
