Onan generator wont start. I tuned it up 15 to 20 hours ago in early spring ie., plugs,oil change and air filter. I also smell gas so i assume it's getting fuel. It's like the generator initially gets power, but then won't turn over.

One of the leading causes of an onan generator starting and then shutting down after some time is a sticky switch. Onan 5500 generator won't start. If not, an ignition issue.

I have an onan 5500 gold generator and it won't start for me. It's only 9 months old and has always started easily before. On manual, the generator starts and runs fine.

One thing to watch out for is onan generators won't let the engine continue to run after you release the start switch unless the generator is producing voltage. When set my onan energy command 30 to auto and the system senses low voltage, the generator tries to start for less than a second but won’t start. It won’t stay running and it quits when i take my finger off the start button, or cuts out and dies.

For proper functioning of the onan generator, the equipment demands a fair amount of airflow. I pushed the generator start button on my inside rv panel just before leaving for a week long trip. This is an issue that seems to happen very frequently.

If it looks contaminated, it is most likely that the oil quality is the reason behind the onan generator won’t start. The cause is the generator’s oil pressure switch which sticks open when the generating set has not been used for a prolonged period.
