Guy,
The other component that you should be looking for is the fuel shut off solenoid. On the passenger side of the generator engine, you will see two or three wires going into 1 1/4 diameter solenoid. On the other end of that solenoid will be an adjustable linkage connected to an arm on the fuel delivering system. That solenoid has to open and pull the fuel shut off arm to allow the engine to run. Diesel engines do not operate as the gas engines we are used to. To stop them we shut off the fuel flow because there is no spark to shut off.
Anyway the point is that if for any reason that solenoid loses power, the engine will stop immediately. It could lose power if the supply leads have a loose connection, or it could lose power because the control systems for the generator intentionally interrupt the power to protect the engine due to low oil pressure or high temperature.
Slide the generator out, and have an accomplice attempt a start while you watch the operation of the fuel solenoid. If it pulls back completely but the engine does not start quickly, I would guess you have a fuel pump issue. If the solenoid drags while opening the fuel shutoff lever, you may have a solenoid issue. Check the wiring. Remove the solenoid, then remove the plunger from the solenoid. Clean it up with WD 40 or magic juju juice of your choice. Sometimes they just get gunked up.
To test the solenoid possibility, hold it open by hand (screwdriver) while attempting to start.
I'll try to get a pic of the solenoid today and post it for you.
