FUEL PUMP

I changed my fuel pump a year ago and it went bad again about a month ago. I have since had intermittent problems with it. Now it won't work at all. I have checked my relay and it is getting voltage. My fuel gauge jumps all the way to the right and then back to the left when I turn the key on. It then settles down. When I installed the new pump it had different colored wires than the other one and I think I have it wired right but is it possible that I have connected a ground incorrectly? Thank you very much.

The fuel pump gets its power from the gray wire the black is ground.

The fuel pump relay only works for 2 secs. and its energize by the computer
