any news on what pin isnt getting proper power? there is a good chance that your igition switch doesnt have a buit in by pass leg in the start position. If this is in fact the case then you can build a relay onto the ignition switch wiring so that the pink wire stays hot in start if it doesnt already. To do that wire a bosch relay as so...
1. splice of of the battery lead (10 gauge red) and connect it to pin 87 on the relay.
2. Splice into the pink wire on the igniton switch and hook it to pin 30.
3. splice off of the purple wire (start lead) and hook it to pin 86
4. hook pin 85 up to ground.
what this will do is applie power to the ignition circuit in the start position. The relay is triggered by the start leg and the igntion circuit is powered by the battery lead. I had to do this on a 1960 pickup truck but have never ran into that problem on your model of car. Try it out it wont hurt anything if you do.
