My Onan Gen Marquis Gold 5500 series will start then die after about 2 seconds. I have checked the oil sensor fuel pump and then I started really checking into this matter and talking to several different people about it (i even went to a Onan repair depot and talked to a factory mechanic. Here is what I learned. These carburators on this model Onan are very touchy. Even a tiny bit of varnish or gum Not running for several weeks or a month cause's The majority of the problems for this generator, The altitude adjustment on these carbs if disassembled or removed from the carb, has to be set with a special machine. I removed the carburator and used a spray can of Carb cleaner and removed the float bowl and made sure that there was no varnish or gum in the unit. also sprayed into all orifice openings and made sure that none where plugged. I still have the same problem. The fuel pump is OK and so is the oil sensor. Error code 32 probably indicates that it is the brushes, stator or rotor or the control module board.
Warning. If you attempt to clean the carb your self. Do not I repeat do not remove any jets or the altitude control. If you do you will have to buy a new carb $218 and labor. I did not remove or mess with the altitude control.lucky for me as the carb is OK and not the problem. I would try installing or cleaning the brushes But there is very little space and it takes a small hand to get in the area where they are located. I think I will take it to the service depot and have them fix it..
