Howdy Don...

Note, I have the FSX version which is different, but could you explain what behavior you found trying to start the engines?  Making sure of course the following:

1) All ENG/ELEC hydraulic pumps commanded ON
2) Both pack selectors comannded OFF (not auto/n/c/w)
3) APU bleed ON, Iso valve ON, ensure APU running and APU "RUN" light solid
4) Wing/Engine de-ice OFF
5) FWD/AFT Left/Right fuel pumps commanded ON
6) Fuel control levers OFF
7) Throttles Flight Idle
8) Select Igniter switch to AUTO
9) Turn start switch to GND and observe that VALVE light comes on, and then extinguishes.  At this point, you should here the "knock, whirr" of the start valve open and the engine spooling up, and should be able to notice oil pressure and N2% increases on lower EICAS.

As for lights, never had the issue, maybe FSX version doesn't have such a problem.

Any time a "VALVE" light is lit, it means the valve position disagrees with the commanded position.  If you've commanded "ON" and the valve light is lit, it means in fact the valve is closed or vice versa on both parts.  Engine De-ice should be off until after engines are running, and Wing De-ice should be off until takeoff checklist (i believe) or maybe it's taxi checklist, can't recall off hand.

There are different variants even of the -200.  Your spec and the spec that CS built the plane from may be different.  I don't know

I fly my CS757 all over the world, and have only found two airports that it didn't know about, but of course it also doesn't know about approach information for most of those outside north america.  It does know the runways though, and I always copy runway data from the map as part of my planning, including interesting waypoints for approaches.  I apparently don't treat my FMC the same way as others, and have yet to experience any CTD issues that I can repeatably attribute to FMC.  I have tried, but failed so far.
