Conversation Between Sportruk and boomerboy

Can you help? I got a cluster from a 95' and put it in my truck which is a 96' and here is where the problem starts. The truck will not start after a lot of really bad language I figured out the fuel pump wasn't working and after removing it I discovered that it has no power and that the fuel gauge is reading backwards, the reason I know this is the truck has very little gas in it(I put 5 more gallons in it, just to make sure). I thought the fuel pump and sending was bad after ohming it's fine. I need to know which relay runs the fuel pump. I've already checked the fuel pump shut off switch.
