I've been running into all sorts of trouble trying to get the Pertronix unit to work in my car. I finally called them, and they said the rebuilt distributor won't work with the Ignitor. I tried to modify it to work anyway, to no avail. I finally gave up and bought a new Pertronix Billet distributor (I've had problems with that Cardone unit since I got it. I think I ranted about the bad condenser years ago). So I put the new distributor in, and realized that I'm stupid: I forgot to clock the old one to the engine body. Once I put the old one in the new box, I lost the setting. So I had to go through the rigmarole of finding TDC and setting the distributor again. Once I did that, I realized I was stupid again: I was still getting no spark, because I hadn't plugged in the wires. I fixed that, and sprayed some starting fluid in the engine, and...
It coughed and sputtered off and on for about an hour, never quite running. I was working on filling the AOD as it ran bit by bit, but I was getting frustrated that it wouldn't stay running. Once the trans was finally holding fluid level, it was time to shift it to fill the rest of the passages, but I needed the engine running. When I did the underbody a couple years ago, I took the gas tank out. I decided I must have lost the prime on the fuel pump, so I poured some gas down the line to the carb, then fired it up again, and...
My Mustang sprang to life for the first time in years!!! I finished topping off the transmission, running it through the gears, but driving it was cut short by the weather (tornado warning followed by marble-sized hail), the need to set the AOD cable, and the fact that I'm not actually insured to drive the car yet.
