Fuel pump power

I recently had to Replace the fuel pump and i know No one else has ever done this but i didn't know i could unplug the wires from under the driver side rear seat. So i ended up pulling the wires out of the plug no big deal fixed that issue but now I'm not getting power to the sending unit and have checked and changed relays and fuses any one else ever had this issue ? If so any help would be appreciated

 

sound like it time for a volt meter. you need to check all the wires and make sure you got them all right i would get a volt meter and double check the wires or run a positive line to the fuel pump to see if it is working.hope this helps LARRY B.
