What might be the issue why this one does not start?

Pretty hard to say. A number of things could be wrong.
The last 803a I brought was similar age with a couple 100 hrs on the clock. It would not start either. It ended up being a leaking fuel hose between the water separator and the fuel filter. Didn't see it at first because it was tuck away, but it eventually leaked enough fuel to notice the puddle forming.

The fuel shut off solenoid is not engaging. Since we can not see the idiot lights, hard to tell. But the set looks good to me.

Shame... Shame.... What do the rules say about discussing items at upcoming auctions??
Sounds like it's not getting fuel to me!

I see vapor in the second crank video, so something is getting in there. Possibly water in fuel? No preheat?

The fuel system is not primed between the fuel pumps and the injectors. Since it was hitting here and there, that does reduce the chance of it being a stuck fuel pump delivery valve.

The machine otherwise looks good and I wouldn't hesitate to pick it up.

I'd bet the primary electric fuel pump is not working ( despite hearing it clicking ) and the fuel system does not have the low side pressure required to start.
Yes, I said low side pressure. For anyone who isn't aware, an 220/003 will start as long as fuel is present inside the IP.
An 802/803 typically will not, unless it has a small amount of pressure ( 2 psi or so ) on the input side.
But that's speaking in general.... not this specific generator , since it's forbidden territory! Now if you'll excuse me, I have a 10Kw generator to go bid on...

This is stopped engine mode. Now look at the film. The black knob is in the same place. So I will ask, is the black knob moving freely in the linkage long slot? Or is it screwed so tight to the linkage that it will not move?

Agree with above, fuel solenoid is not retracting, clean looking set.
