Onan generator won't start

I have a 1994 Winnebago with a Onan Emerald Plus 4000 that won't start. At first I thought perhaps because the gas gauge was just above 1/4 tank may have been the reason as the fuel pickup for the genset is around the 1/4 tank level as a safety device so as not to run the coach out of fuel while sitting at one spot. Well $100 dollars worth of fuel later still no go. The oil level is not low either as a matter of fact maybe even just the slightest amount above the full line. Checked for spark and there is none, thought perhaps because of one of the previously mentioned but oil and gas are not in short supply. Ok so now if any of you are familiar with these RV's you already know that if the genset is not on a slider they are a real bear to diagnose further and at this point I am just not motivated to remove the genset to gain access. Is there something I am missing here and if I do have to lower the genset what are some typical problem areas to look at on these. I might add it only has 80 hours on it and has always started and ran perfectly to this point. Thanks in advance. Doug
