Miek --
Nope, dead... or at least trying to die.
I originally thought low fuel might be the problem when it first occurred,
having run out of fuel once before understanding the pretzel logic of the
General's fuel system. The generator stopped running on our way home, and I
was cutting it close on gas.
I filled the tanks and the genset still wouldn't start. Here was my
troubleshooting procedure:
Slid out the power drawer, pulled the trigger wire off the starter solenoid.
Took the pump to carb gas line off, put in into an empty gas can.
Hit the genset mounted start switch. The fuel pump pulsed erratically, like
it needed a pacemaker. No fuel delivered.
Thought the filter in the pump (a Facet) might be plugged.
Took off the bottom twist off, pulled out the barrel shaped filter. It was
clean as a whistle. Put it all back together, discharge hose in the gas can,
held the button to start.
The pump pulsed for a few minutes, then stopped. Tapped it with a wrench, it
would pulse a little, run for about 5 to 10 seconds, then stop again.
I could repeat this run / failure cycle by tapping on the side of the pump
itself. Duplicated the same condition from the control on the inside of the
coach.
I grew up on a farm, and this same style of pump was used by John Deere on
their gas combines, and they would fail the same way. (I think they were
made by Bendix though)
They later had a smaller squarish style model that used an external mount
transistor. I think I'll call my JD parts guy and see what his price is on
Monday, since I imagine all the other parts folks are at the Marion rally.
Even though I have multiple Onans at work, no one gets a deal on parts from
these guys.
Thanks for the thought. I found out the hard way that when the gas gauge
reading for either tank on a GMC reads 1/4 or less, you're already walkin'
if you're driving uphill.

Are you just out of gas ?
