Wiring help!!!!!!

Check voltage as I described. Make ABSOLUTELY certain the box is grounded.

First fix whatever is causing the low voltage. If it still wont run check coil NEG voltage with key in "run." If it's above 1/2 volt or so, either box is not grounded, or it's bad

Confirm, the one pin you are talking about goes to the pickup coil? Leave that alone. DC voltage is meaningless on the pickup coil
