I'm working on switching my brothers '66 catalina to a h.e.i. ignition. The ignition is out of a later pontiac and has an aftermarket coil on top of it. The problem is it won't start. I had ran a wire from the battery to the positive on the distributor just to test it and it would barely try to start but would never start. I had made the mark on the firewall and lined it up and put the wires in their places.
Anybody have any ideas on what the problem is??
