318 Won't Start? And I tested as much as I could I think?

I was mostly looking for an update LOL. The coil doesn't matter for polarity in this situation. They will "eat plugs" if run for long periods backwards, and don't make as strong as spark "so to speak." so far as starting and running, should not really matter

"Measurements" yes, measure from coil terminal to ground

With key "in run" not running, coil NEG should be quite low perhaps 1/2--1 volt. This is because the transistor in the ECU is conducting and holding the coil NEG "close to ground"

The POS terminal varies depending on the coil and resistor, should be anywhere 6-8 or maybe 10V

"Cranking" the coil POS should be "same as battery and at least 10-10.5V
