I purchased a 1983 SC cabriolet a couple of weeks ago. The car passed a PPI and ran very well for most of ~120 mile drive home. Then the fun started.

About five miles from my house, I experienced a slight hesitation going uphill.
That worsened progressively and the car died about a mile from my house.
I got the car restarted and into my garage, but the car was running very rough. After reading the forums, I replaced the relay under the passenger seat, but the relay did not fix the issue. The spark looked weak (more orange than blue), so I replaced all plug wires, distributor cap, rotor, and ignition coil The problem progressed to a crank but no start condition, though I did get the car to start once after I got the new coil. It ran for about 5 minutes; somewhat rough at first and it started to smoot out. I thought I was in luck, but then the car died... Since then, I have discovered that I now have no spark.

My "green wire" looks okay but I realize it could be bad. The CDI box makes the squealing noise as expected. I tested between pins 31D and 7 at the CDI connector and I get 586 ohms resistance and 0.8 volts ac (not sure how to measure pulse).


I've read countless posts and I'm somewhat at a loss at this point. I would appreciate any suggestions.
