Onan 5500 Starts then stops after releasing button

This is a 2002 Fleetwood Fiesta with a Onan marques Gold 5500 Generator set

:D
My brother just purchased the motor home, and the generator would not start,
  1. I had diagnosed the fuel pump though after removing the fuel pump and bench testing it worked, I then re-installed the fuel pump. After re-installing the fuel pump, it would not start unless I had sprayed carburetor cleaner into the carb which then it ran good. I diagnosed it as the carburetor therefore I removed the carburetor dissembled it and soaked it overnight in carburetor cleaner washed thoroughly and reassembled and installed. It then ran great though we were not producing 110 at after the coach relay panel.

After visual inspecting all involved to my coherent ability i discovered the light flashing three times pressing off side of rocker switch for a split second in would blink 3 times pauses then blink two times referring to code 32

    When ours wouldn't stay running it was an extremely filthy air filter. Changed filter and it ran like a charm. Have you checked it recently? We apparently hadn't for awhile and it let us know.
