I'm pretty sure the fuel pump relay has a constant 12v going to it and the computer grounds the relay when it need to run the fuel pump. That is why you are seeing the pulse on the ground wire.

Big Scott is right. Constant 12v to relay, computer grounds relay, pump operates. Don't try to read too much into this stuff, it's not that complicated.
