I have a 2011 ford f250 and I have no trailer lights, I have checked all fuses and relays, but no luck, I have used a light tester to check the 7 way but no power. I need some help.

did they work at first or did you lose them after connecting a trailer? do you have a multi meter?
Well I also have from factory a fifth wheel plug and it also does not work, but they used to work, but upon hooking up my car trailer today they do not work, I do have a meter.
Ok, checking schematics now.
do all the lights on the truck work as they should?
Yes all truck lights work fine just no power to light coupler
I would check the ground for the BCM, G104. Shows it by the firewall near the master, left rear of engine compartment.
Make sure f70 and f100 are good in the BJB(battery junction box)
they power the reverse, left and right lights
check f28, F55 AND F90 too
use the meter to see how many volts
ok make sure F26(30 amp) in the BJB, use the multi meter.
