Time crunch & no spark :(

Are you running the Chrysler ignition box too? Why? That means you are running two ignition systems stacked on top of each other. Or am I missin something? If you are runnin the coil designed for the Chrysler ignition box, it cannot see 12V and that's most likely the problem. A toasted coil. If it is, then you need a coil designed for use without a ballast that needs a full 12V and eliminate the Chrysler box.
