318, E-Coil, GM ignition module, Chrysler Distributor...need wiring help!
How do you know it "clearly" needs more voltage at the coil? Have you measure it at the coil with the relay on?
Also, please detail how you have the 30, 85, 86, and 87 pins wired. Where is the relay trigger coming from? Blue or brown wire from the ballast resistor?
