Onan gen set relay issue?

[HimHerBoySissy]

Hi

We have a onan gem set on our lagoon 440. It's the 11.5kw model. Recently we start her up, she stays going for about ten seconds then shuts down. The fault is ree flashes which is see the manual. The code is 33 ( 3 and 3 flashes)

On a second try after about 30 seconds of priming we get her going. Then she cuts out after about an hour to an hour and a half.

I have been told that this may be because of corrosion etc in the relays. I am not sure If is is the case. Has anyone e
We experienced this and if so what ease diagnosis to solve the problem. I am current.y in the rio dulce.

Cheers

Sounds to me like you have a small air leak in your fuel line.

That would mean air entering somewhere between the tank and the fuel pump. If you have a primary fuel filter check it too.
