Uh, I think (remember you have a different management system than I am
used to) that the coil *always* gets power to one terminal of the
primary winding.  The elec. ign. system grounds the other terminal of
the primary, to collapse its field, inducing a field in the secondary as
it happens.  The secondary has a lot less windings, so the field it
develops is a lot higher voltage.  This high voltage is then (or
simulaneously) grounded through the distributor to the spark wire to the
plug.

Unplug the coil and measure its windings, should be in Bentley.

you could have a bad hall sender, bad ignition computer.  No spark when
cranking, right?
