2003 Chevy Silverado, Fuel pump?

[whtsthislif4]

The fuel pump went out on it and I replaced it. I tested the old one and it was definitely dead. But when i installed the new one it's still not working. I checked all the fuses and switched the relay with a known good one and it's still not working. I looked in the owners manual to see if it has a fuel shut off switch that may have tripped but it doesn't say anything about it having one. Anybody run into this problem before and can possibly steer me in the right direction?

Jack it up,loosen the straps holding it on,remove the lines[usually 3],unplug the wires,remove the ground to the frame,take off the straps and lower it to the floor.Using a brass punch,turn the retainer until the slots are lined up on the retainer and remove the retainer,lift the pump from the tank and drain and clean the tank.
