1991 Winnebago Warrior : Generator switch ?

We just bought an old Winnebago Warrior with a Onan Genset 4000 Generator.
I know it was working but I can not start it as the fuel pomp is not powered.
I am not able to contact the seller and I can not find any switch to turn on this pomp.
Any help or information from a Warror's owner will be welcome.
I attached pictures for reference.

Thanks in advance and sorry for my poor english.

I had a 1991Warrior just like yours. There is NOT a switch to turn on the fuel pump. It should be energized when you hit the start button. How are you attempting to start the generator? From the start button on the dash of the motorhome or the start button on the exterior (on the generator)? You may want to check for a blown fuse or circuit breaker that has tripped. Here is a link to the wiring diagram. Table of Contents. You may also want to check out Winnebago Generator Problems! They say there is a fuel pump relay behind the carburetor and air intake.

Hello Dali
Thanks for your answer and for the links that helped a lot.
I do not know exactly what was wrong but with your docs and the help of Holley Generator in Sacramento it took only 1 hour to fix the issue.
Now my 28 years old generator (but only 160 hours ran) is generating like a charm !
Thanks again for your help.
I will post more SOS for sure as all our love will not be enough to make it young again
