NHE 6.5 - Not Getting Gasoline
This is an Onan NHE 6.5 in my 1986 Holiday Rambler Class A 30' motorhome. It is the original equipment. It has run well most years since I have had it - 11 years now. Twice - once last year, and n...

Brian,
I have two possibilities, both are based on my experience with my own Onan that is somewhat older, but very similar.
You can download the manual at NHE Manual
First is fuel: Can you unplug the wire on the solenoid? If you can, do and hold the start switch. You should hear the fuel pump clicking a fast and then slow down. If you can't get to the solenoid you could do this at the control board, but I don't know your level of technical capability so I don't want to suggest this. Now you know that the pump is working or not.
It can also be a cracked fuel line - Any Place. This is very common with older vehicles as the line age out anyway and the alcohol in new "Motor Fuel" is doing damage to all the old rubber non-alcohol compatible fuel lines. If you can't find a crack, just get some new line and replace it all.
The next is the "shuts down after a few minutes problem.
Does the unit have its own battery? If it does, check the running voltage. The charging system is cheap and dirty and can fail easily.
Good Luck
Matt
