Start Valve Fail Open on Ground

Gulfstream GVII

Eddie sez:

This procedure is greatly simplified: engine an APU bleeds off, fuel control off.

I have heard that the starter valve on this engine can be "exercised" to loosen it up if sticking, or that it can be manually controlled during a start attempt. But I haven't seen the procedure in writing. (Yet.)

Everything here is from the references shown below, with a few comments in an alternate color.
