HEI Install Problems

The distributor I'm using in the car is the same one that was running fine with the original ignition. Right now I just have it ziptied to a BIG cpu heatsink, but it's on there pretty good and flat and there was even a little thermal paste left on the heat sink from before. Nothing else connected to the negative on the coil. Just the C terminal on the module. Nothing on the positive besides 12V from battery and + terminal on module. Maybe all the quickly made crimp connections are adding up and it's too much resistance... Wouldn't think that would matter though.

For the ground I took a screw and screwed both a wire directly to the battery ground and the module G pin wire into one of the screw hole liners. There's continuity from the G pin to the screw hole liners, so they're all the same ground. I'm also getting 12V between the other screw hole liner and battery +, so it's grounding as far as I can tell.

Maybe I'll go to the junkyard and grab another module tomorrow and see if that's my problem... It WAS pulsing while bench testing it and spinning a distributor by hand, but my multimeter isn't high enough resolution to actually show the exact voltage being put out.

I am correct in that the stock mopar ECU should be unplugged correct? The wiring over there shouldn't be connected with anything at this point anyway since the old reluctor connections and coil connections are disconnected.
