Onan Generator wil not Prime
I have a 2013 Onan 5500 gas generator. I was going to exercise it today and when I hit the prime I cannot hear the pump running. It turns over fine but will not start. I assume it not getting any gas....

On mine the faults are read by counting the flashes on the rocker switch. I am not reading any faults. My manual does mention an over cranking fault (if engine does not start after 30 seconds) but no mention of over priming. Tomorrow I will check the voltage to the fuel pump, it should be fused somewhere. Thanks for posting the link to the service manual. It should be a big help tracking this down.
You're welcome. It looks like a very high tech genny. They keep changing like everything else. I would exercise it often too. It's probably not something you would want to start paying to have fixed. I have worked on whole house stand by units that self exercise every week for 15 to 20 minutes. AND that's with running on Nat gas or propane not todays funky gasoline.
