Russell,
The short answer to your question is Yes.
I found this out the hard way.
Recently, I too started my rotary for the first time
using the EFI. (had been run previiously with a carb)
As soon as I turned off the cold start switch the
engine would die. I asked Tracy about this and he said
to check the primary injectors. Sure enough they were
both stuck closed. Using the advice from the archives
that someone posted I wacked them on a block of wood
and hit them with 12v pulses until they started
clicking again. Once they were re-installed in the
engine it started fine and ran without the cold start
switch on. Apparently the way Tracy increases fuel for
starting is to turn on all the injectors. If I had
know this it would have been easier to trouble shoot.
(I do not have the injector disabling switches
installed, as suggested).
I had another successful ground run this weekend and
was able to achieve a peak of 5440 RPM static.
