Ok, I got it figured out now with the help of FSUIPC support.
There is nothing wrong with Captain Sim's gorgeous 727 series.  The fuel cutoff switches were locked up because they are set with "Mixture1 Rich, Mixture1 Idle" etc. and the same with #2 and #3.

I went into FSUIPC program and set those to the buttons below my throttle levers on my CH throttle and they work Perrrfect now.  I can start up my engines like a pro.

If you see that you can't start the 727 with the procedure and need to Ctrl+E, just reload the plane.  It will work perfect then.  For some reason sometimes it doesn't load right the first time.  Probably more of an issue with FSX itself.

It might be a good idea after you select it in the setup and it loads up at the airport, to just reload it again through the menu at the top.  First shut down the engines then just reload it.
That way it should be ready to start up following the procedure.

Now I only have one other little problem to figure out and it is not Captain Sim's fault either.
My ALT HOLD switch is locked up and it did work at one time.  I figure the problem is probably similar to the fuel cutoff switches.
