While recognizing that the solutions within my meager mechanical abilities probably wouldn't work, I went ahead and changed the fuel and oil filters again and also changed the fuel pump.

Now, if the unit starts at all, it will shut down with "check apu engine" on the display. Although the oil level is fine, the only light burning inside the engine compartment is "Oil".

Any help would be appreciated.
