My brake lights (xcluding 3rd), turn signals ( from & back) are not working. Also interior turn lights. Checked all bulbs, fuses and relays.

Most recent work on truck that may have affected: removed bed to replace fuel pump and previous owner recently installed new stereo system.

My running lights didn't work, but turn signals, hazard lights and brake lights worked. The previous owner removed the bed or cab to replace the fuel pump and pinched the wires. That may be your problem.
