Finally got around to troubleshooting my "dead in the water" Onan. Found a broken positive battery lead lug at the pass through insulator. Engine cranked but no start.
Fired right up with a squirt of starting fluid. Disconnected gas line and determined it was clear (siphoned gas out.)
I read about the K3 , K1, K-whatever solenoids..... etc.
Before I dig in deeper, thought I'd ask all of you who have been through this, if there is a routine cause for "no-gas" situation and start there.
As always thanks for all the expertise here,

Bad fuel pump makes for a great no-gas situation.

Try putting a jumper wire from pin nine to pin five on the control board. You should hear the pump run when you do this. If you don't, check the wiring or the pump. If the pump is pumping gas, the tone of the pulse will change when it builds up pressure. If the pump does not come on with the jumper, it could just be gummed up from old gas. The factory pump is pretty simple to disassemble and clean up. try that.
The only problems I have ever had with my Onan have been a bad LOP switch and a bad fuel pump. The pump went bad gradually over time but I ended up replacing it with a Mr. Gasket unit from Jim K. Hopefully your issue is as simple as a gummed up pump and not a control board issue, but if it IS the board, replacements are available.

If your pump is gummed up you can usually pour in some carb and choke cleaner and let it soak awhile and them pump some through and it will usually free up.

check the oil level if it is low it can not work, also there is three wires at the top back on the regulator, pull them off and tape them
one is a single wire and the other is two wires together. make sure they do not touch anything at any time tape them good
do not tape them together.
leave them off so there is no shorting from them anywhere. Google duane simmons onan and you should get a lot of info.
mickey :-) there is also a part in the back that could go bad before the board, ask JimK for it. You have to mark the wires if you change
it try and get duanes dvd it shows you all this. mickey :-) anaheim ca. 77 palm beach.
5 and 9 on the board starts the fuel pump. if it doesn't spray something through it to clean it out and try it again. etc.
i am having the same trouble. My last shop told me they started it, but it is obvious they lied. It has not been started since i bought it.
It was low on oil for one thing really low, so they did not start it for sure. why some shop people treat others this way is amazing.
the bowl could have a stuck float and plugged needle also i guess. I am trying to find out myself, the dvd is worth it if you have
an onan.

Wait wait wait. On the Voltage Regulator, the two wires that are taped
together, aren't they supposed to be electrically connected at the ends?
The way you're describing it, they're kept electrically seperate.

Robin
There is a single wire. Tape that on the end.
Then there are two wires that connect to a single lead.
Leave them connected together and tape them off.

Ok, that's what I thought, and that's what I did.
Words mean things, we attorneys use words like surgeons use scalpels. :)
Ambiguous language causes us problems. :)

on the top of the regulator box.
one wire close to you pull off the tab. tape it.
the one behind it is two wires attached to each other and go to one tab, pull them off keeping them together and tape them off
then fold all the wires and zip lock them to the back area to the 110 wire out of the way.
This allows the onan to start much faster for it is not hunting for voltage for no reason before it starts.

Mark,
A number of other GMCer's have pointed you towards the fuel pump. There is another component that could cause the no fuel problem
and it is the fuel shutoff solenoid. It's down near the fuel pump and has two leads going to it.
I took mine out as it serves no real purpose the fuel tanks are below the Onan and fuel won't flow up when the Onan is off.
That is true even in Australia where we're upside down! ;-)
Regards,
Rob M.

From: mmmm ka
Finally got around to troubleshooting my "dead in the water" Onan. Found a broken positive battery lead lug at the pass through
insulator. Engine cranked but no start.
Fired right up with a squirt of starting fluid. Disconnected gas line and determined it was clear (siphoned gas out.)
I read about the K3 , K1, K-whatever solenoids..... etc.
Before I dig in deeper, thought I'd ask all of you who have been through this, if there is a routine cause for "no-gas" situation
and start there.
As always thanks for all the expertise here,
Mark

actually it would be good to run the gas out when you stop using the onan to stop the gumming of the gas. maybe. that thing
is a good idea to use. the fuel turn off, is there a button for it?
do all your nuts turn the opposite way down there?

It actually does have a purpose.
There are times that pressure could potentially build up in the fuel system and overpower the carburetor float in the (non-running) Onan. This potential is greater when the coach is pointed up hill with a full tanks on a hot day and the tank vents are not fully up to spec. (It has happened.)
IE: It is an emissions thing.
If it is bad I would remove it without replacing. If good I'd leave it in. JWIWD.

Mike,
I agree in the circumstances noted below the solenoid does serve a purpose, however, the chances of all four of those conditions to
be met is rather remote AND the root cause of the problem was that the tank vent lines did not function properly. If they vented the
pressure as they should the problem would not have occurred.
So what did the individual that suffered the problem below do? Obviously he had removed the solenoid so his options would be to
re-install the solenoid or bring the vent lines up to spec. Seems to me that the better choice would be the latter.
Regards,
Rob M.
