1987 Winnebago Elandan generator

Hello everyone, I am new to RV's. I bought a 1987 Winnebago Elandan and could not get the fuel pump to send gas to the motor, turned out there was no electrical reaching the pump. By passed the line and put a on-off switch to pump to get it to work for now. My issue is i'm still not getting electrical to generator pump, Is there any button I need to turn on so pump can turn on? I would like to find a manual if possible.
Any help will be appreciated.

Ps: I am totally taking all the old carpet and old sleeper and cushion and putting new ones, will upload pics when done. Slapping on laminate flooring
