2009 Cummins Onan Generator 4000 RV QG Not Starting Fix 

You gave me exactly what I wanted and needed to see and hear.Good job Mr.Cook

Excellent thank you, now I got a project, 😊

I really appreciate how methodical you are. I’m a new subscriber and look forward to checking out your cooking videos and any future repair videos. Thank you!

Most technical problems and you have a lot of common sense I'm subscribing because you're another Craig and I want to see what you cook 👍👍👍👍

Thanks for the full in depth discussion!

Thank you for the tips

Chef Craig, just stumbled onto your channel. However, your no-nonsense diagnosis and delivery really was helpful for us non-mechanical type. I found it very informational and increased my knowledge on the subject. Thereby leads me to dissecting prospective problems going forward before throwing in the towel and paying a mechanic $$$$ untold of amounts of my hard-earned money. Thanks again, and keep creating content. Always, Syn Silver.

Really nice video I love that at every step you went the extra mile and took care of the details like the fuel lines too. :-)

What a great video. It’s exactly what I couldn’t find but, exactly what I needed. THANK YOU 🙏 from one Chef to another. Guy.

Thank you the reminder course Craig. Well documented - the actual hands-on work moments are challenging but DIY is possible by staying patient, think it through, take notes, take your time. Take heed on emplacement parts though, as Craig mentioned. In May 2019, my 2007 Onan 4000 was suffering the shutting down after 10-15 min from cold or after allowing to cool 20 min, and repeat with shutdown in 5-10 min. Same issue as Ken Romaine's comment in this thread. Pump overheats during active use and shuts off. Onan pumps were scare that June so I utilized the same "use this, it'll work", knock-off E11007 pump Craig is removing in this video. But I did replace the available proper Onan filter and new fuel line to carburetor as did Craig. I didn't think of the in-line shutoff - great idea, if it won't leak. Nice touch though and great planning for future. We haven't been actively camping for 4 yrs for multiple reasons but I had been starting unit for 1/2 to 1 hr periods. Yesterday's scheduled generator & AC load temporary "exercise" resulted in raw fuel escaping from under that green control board. Something gave up and I have to believe it was the pump. In Craig's opinion that it'll give out "in about a month" appears correct (assuming real world daily usage). As soon as I have the proper parts and materials gathered, I'll be doing the same as Craig. Safe and happy travels to all.

Excellent video tks

iCraig this is another Craig I cannot stand Onan generators every RV that I've had I've had tons of problems and expenses with them even from new I have replaced my class a generator where the champion generator right why are the Onan was and put cooling fans and I hooked up exhaust and I hooked up a pump and hose to fill the generator from my main tank it's remote start as well as 3500 watch and I have no issues whatsoever I will never own a Onan product ever again nice seeing another Craig out there😂😂😮😂

Thanks my husband will check ours now and see if this is works

Good, logical process for troubleshooting fuel issues. When troubleshooting y new-to-me 1999 motorhome genset, I found the fuel line had been replaced sometime previously but not connected at the tank, probably because the nipple was located on top of the main tank and it required dropping the tank to get to it. I got that done and got fuel flowing all the way to the carburetor, but still no joy. I then tried squirting some starting fluid into the carb and still no go. I then got a spark tester and found that the plug is not getting spark while cranking, but, interestingly enough, it does get spark after the switch is released while the the motor is winding down. I'm at a loss ....

The pump doesn't run until the red light comes on so you don't want to let go as soon as the light comes on you want to hold it for about another three or four seconds. If you hold it until you hear a change in the sound of the pump you'll know it's up to pressure and the bowl is full.

I had the same issue. Did what you did. But before going to get a new fuel pump, I drove my RV a few miles (I had checked the fuel level, and started it a few times). Guess what?! I found the RV fuel gauge had been stuck, and the level was below 1/4 a tank!!!! So no issues with the generator!

Good job!!!!!!!!!!!! Smart

I just bought an '04 Winnebago and the generator wouldn't start. I pulled the fuel line off and put it into a gas can, then ran the primer for a few minutes. After I got about a quarter gallon of gas in the can, I reconnected the hose and it started right up. That's when I discovered the generator only had 51 hours on it. That line had BAD gas in it.

My 2006 motorhome with an Onan 4000 would start and run for about 15 minutes then stall. It would only restart after cooling off for about 30 minutes. The stalling was caused by lack of fuel into the carb. Once again it was a failing Onan electric fuel pump.failure.

They call it "sea foam" because it started as a product for 2 cycle marine engines. There have been mixed reviews online. Scotty Kilmer did do a review of "Gumout Mult System Tune Up" where he used a scope on the cylinder head after 3 tanks of treated gas to verify improvement.

I need to try this. How did you rig the can with the fuel line?

Great video, can you tell me how you integrated the hose fitting into the bean can? I would like to make me one of those.

I'm interested in the fuel shut-off valve. Do you have a link?

Question for you. I had the same problem and fixed it thanks to your video. However, while hooking stuff back up I cannot figure out where I took the white 110v neutral off of. Do you know where this hooks up to?

Kidney beans can creat gas 😂. I suer am an adult but that was good

Ok , You Say Negtive Cable , but You Are Actually Taking Positive Cable Post !!! Yes Negative Cable Should Be " Removed " !!!

The answer is... Take the carb apart and clean it! Especially free up the shut off solenoid plunger(and it's easy to get to). Btw, you have to prime it a lot longer than you did... More like 10-12 seconds and crank it for 5-10 seconds(when cold). Once it's warm it will start right up.

AINT GOT NO GAS IN IT!!!!

Mine starts, runs for 3 min then dies.
