We have a Onan Genset that we have not been having any problems with until now. In the evenings after work the generator will start up after we fiddle around with it however in the mornings the generator will crank but won't start. It gives me an error code of 14 however the genset had not been running.
Yesterday we changed the oil, replaced the oil and fuel filter and the generator started right up. It has 3/4 tank of gas and the fuel pump is working fine. We were going to replace the spark plugs however the parts place told us we had one spark plug even though I told the woman I had two so my husband only brought home one spark plug.
This is the only thing I can think that could be wrong except maybe the fuel cap is not vented but this has never given us any problems before. When I go to put gas in the filling station and remove the cap it will suck air in. It did this yesterday evening so I am thinking that after I filled up the tank w/ gas and hubby went to start the generator he thought that the oil change, fuel filter and oil filter change worked. This morning when it wouldn't start he told me to check the oil level which was full however he insist that is what the problem was but I don't think it is the problem.
Has anyone had a problem with the gas cap not being vented causing it to not start up until you take it off and put it back on? I was thinking that maybe it is the oil sensor unit however that doesn't make sense to me since it will start in the evenings after I open the cap and put it back on. I will be replacing the spark plugs this evening when I get another one so I can replace both at the same time.
