Overlook the second diagram. I wasn't able to delete it.
A lot of people don't understand the two times there should be 12 volts to the fuel pump. You have that covered already. Concentrate on the dark blue / orange wire. That's the 12-volt feed for the fuel pump. Terminal 30 in the fuel pump relay's socket should have 12 volts all the time.
For these tests, a test light can be more accurate than a digital voltmeter. If there is a high-resistance break in the circuit, a voltmeter can falsely show there is 12 volts at a point, if you have the plug disconnected to take voltage readings. The readings are valid only when everything is connected, but when that is not practical, the test light completes the circuit and causes current to want to flow. That current is what forces the high-resistance break to show its results.
