Onan Gold 7000 Starts fine, runs for 10 seconds Code 36

[kmb1966]

My Onan starts easily, runs for about 10 seconds, then shuts down. reports code 36. Try to re-start but will not, spits fuel out of the intake on carburetor. Wait until the next day, will start right back up, then dies after about 10 seconds. Code 36

Exact same problem here. I changed out the fuel filter which cleared the 36 but resulted in a 15. Had to replace the carb to clear the 15. Pump was not an issue in either case. Original pump still on the unit with a new filter and carburetor. All is good one again! Runs like a champ! Good luck!

But mine only runs for 10 SECONDS. I have both breakers on the genset OFF.
The choke is closed. I push start, it fires right up smooth as silk. choke opens up like it should. runs perfect. but only about 10
seconds.

After that. Will not start. tries to start but won't. Fuel spits out of the carb/choke area.

Wait a few hours and it will easily start up again, but only 10 seconds of runtime.

Looks like this guy fixed the same symptoms by replacing the fuel pump...

See if this works: Turn off all demands on the generator until it is warmed up. That includes converter, refrig,water heater, microwave, whatever. My onan doesn't like the extra load at startup of the converter. Once running for a couple of minutes it is fine. Also be sure your elevation dial on the generator is set for you current elevation. Good Luck.

Dirty carb and/or fuel pump.

DO you exercise gen monthly?

Do you use any Stabil or SeaFoam additive to gen fuel?

Code 36 is an uncommanded shut down. This means the genset control did not detect any fault, the genset just stopped.

Usually this means fuel, but can be caused by carb issues, plugged air cleaner, bad plugs, magnetos or anything that would cause an engine to die.

Check your fuel first.
