If by "properly grounded sparkplug", you mean that it is the ground
to which you have the starter switch connected, (also the negative
side of the 12v supply) this sounds like it will work.  I'd expect
to get two sparks, one when the remote starter switch is pressed,
and one when it is released.  The sparks correspond to the magnetic
field of the low voltage side expanding and contracting respectively.

Let us know if this works!
