Won't start.
Steve Adams:
Arden, thanks for the new idea. I just got the coach back from Pacific Power Products in Ridgefield, WA last week after it had been there for 3 weeks. They repalced the fuel filters and said there was NO algea in the fuel system. There were also no active or stored engine codes so they were stumped as to where to look for the starting issue.
When we stopped for fuel it was after about 1.5 hours of driving on OK roads, no significant grades. We stopped about 15 minutes earlier and shut down to unhook the toad as it is a little tight getting it through the gas island. After disconnecting, it started right up and driven less than 10 minutes to the station where I filled up.
The only odd thing I noticed was the fuel filler cap sucking air as I removed it. When I tried to start post fill up, the noises the engine made were "normal" as far as I could tell. It just seemed that it would not fire. Battery voltage was greater than 13 per the gauge, I tried tying in the other battery to no avail. After I called the Insurance company for the tow, I tried again. At this point the coach had sat about 25 minutes. Same as before. When the wrecker showed up I tried one more time and it fired up as soon as I hit the starter.
We have had no issues since and this has been the only occurence.
Thanks to everyone for their input so far. Please keep those ideas coming.
Thanks, Steve

If the fuel tank is sucking air when the fuel cap is removed then you have a vacuum being created by the lack of air replacing the fuel being used. Eventually the vacuum will be so great the fuel pump cannot overcome it and the engine refuses to run from the lack of fuel. If I were you I would be investigating the fuel tank vent for an obstruction. I know you have been actively chasing this problem so hope this will solve the delima. GOOD LUCK!
Tom Rogers:
Strange about the vac build-up. I know our 06 has an overflow tube on top of the tank because I experienced an over-flow/top-off once. What I don't know if that tube is open both ways or has a one way check valve allowing out flow but not in. I've heard of people drilling holes in the fuel cap but I won't recommend that. Also I looked thru my operators manual and couldn't find and reads about venting. When in doubt how about a call over to Bend.
Bruce Benson:
At this point I would let it go. Too much water under the bridge to ever know. Just put a little extra time in your calender in case it happens again. Remember the number of times you tried to start it and how much time elapsed then duplicate that.
If it ever does happen again try cracking open a bleed plug on the fuel pump and see what comes out as you crank. Also consider calling a service truck rather than a tow truck.

Richard And Babs Ames:
Fuel tanks are vented as mentioned above and you may have a clogged vent which would allow a vacuum to cause the fuel starvation similar to a clogged fuel filter. You may want to check the tank vent or if it happens again and you remove the fuel cap and your engine starts you will know the problem and what to do to fix it.
