Hello again,
Have you checked the fuse supplying power back to the fuel pump? If you shorted out the power wire from the relay to the fuel pump then yes it would blow a fuse, that's what the system is designed to do. I have included two diagrams in the diagrams below. The first explains how a relay works. The other is the fuel pump relay circuit for your vehicle. See the light green wire that is going from fuse #30 to pin #2 on the relay. This wire has power only your vehicle is in run or start on the ignition switch. The black/red wire coming from pin #1 of the relay is going to a ground. This is the control side of the relay. So when you power this side(run or start on ignition switch), it allows 7.5A of electrical current to energize the electro magnetic coil. When the coil is energized it pull the gate closed to make a circuit from pin #3 to pin #5. Pin #3 is fed from fuse #60, via the red/green wire, which is hot at all times. Pin #5 goes to the fuel pump(+) via the yellow/black wire. When the electro magnetic coil is not energized(ignition switch NOT in run or start) the gate will open, breaking the circuit to the fuel pump. Diagrams below.
Thanks,
Alex
