Onan Generator wil not Prime
I have a 2013 Onan 5500 gas generator. I was going to exercise it today and when I hit the prime I cannot hear the pump running. It turns over fine but will not start. I assume it not getting any gas....

Let me get a little more info. Did you do it this way? You probably did but I ran across this part so thought I'd check.
Press and hold
the stop switch for more than 3 seconds to cause the
fuel pump to prime the fuel system.
Startup:
Press and hold the start switch until the
genset starts. The controller:
1. Enables cranking.
2. Energizes the fuel pump E2 (gasoline models
only).
3. Depending on model:
A. Enables fuel injection
B. Energizes
the gasoline carburetor fuel
cut-
off solenoid E3 and choke heater
C. Energizes LPG fuel cutoff solenoid E3.
4. Flashes the field (F1-F2).
5. Flashes the status indicator light during crank-
ing.
6. Disconnects the starter when engine speed is
greater
than 1300 rpm and turns the status indi-
cator light on solid.
7. Turns on Switched B+ (remote pin J8-F).
8. Enables
output voltage two seconds after oper-
ating speed is reached.
