Hi John,
The Mode switch should make no difference.  One pole of the injector
switches grounds the Cold Start input but the other pole is just a
power switch for the injectors.  It should be very straight forward to
test whether the switches do or do not remove power from the injectors
when in the disabled position.  If you remove power from them, the
engine HAS to stop if you kill both sets of injectors.

I'd consider this a 'Do Not Fly' until fixed issue.  Something is
seriously amiss.

Tracy
