Cummins Generator Dies After 2-3 Seconds

Recommended Posts

The Cummins / Onan generators can be primed after one runs them out of fuel by holding the stop side of the switch down for a good 30 seconds to a min.

Then try to start it again.

Let the group know if that worked and we will go from there.

Rich.

bigben6969,

Any update?

Check and see if it has an auto start/auto stop feature. If so double check your settings. I accidentally turned on my auto shut down and it will not run if the batteries are close to a full charge, even if the A/C units are turned on, it will still shut down.

Yea, it doesn't make sense but it was designed that way.

I know this is a little late, and is the opposite of your question. I worked on a friends 4000 watt Cummins/Onan Saturday two weeks ago, he has burned up two starters in two years, while working and getting it back to running.

I noticed that when he pressed the kill button, he continued to hold that button till the engine completely stopped. When I showed him that all that was necessary to push then release, he explained that no one had told him this.

What was happening, holding that button, he was actually flooding the carburetor, causing the next start to be a hard start.
