Electrical problem
1998 GMC C1500 V8 Four Wheel Drive Automatic
were does the gray wire goes from the fuel pump to what? I put in a new fuel pump, but now I have no juice going to the fuel pump. Why? Can you help? Thank you.

The gray wire goes back to the fuel pump relay and the fuel pump/oil. Pressure switch. Do you hear the fuel pump for a few secs-if not check the fuel pump relay and ECM B fuse.
