It is possible the Brown wire does backfeed thru the resistor and into the Blue wire, this is if the the brown wire is still connected at the resistor or to the Blue wire with the trace. If this is true then the MSD may sense the voltage back fed in the wiring during cranking.

The easy way to see if this is true is to test the brown wire for voltage when the car is running.


Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.
