Ok, looooong story short, I had spark and now it doens't look like I'm getting any. The C950 doesn't fire the injectors until it senses an RPM signal. Where does it get this signal? The dizzy? The ign. box?

One more thing, I picked up the TPI harness from holley as well. I cut out most of the factory harness to clean up the engine bay and avoid re-pinning the connectors for the new ECM. I still have the white wire and big pink wire connected to the fuse box that goes into the car. Those are hooked up to the ign. components. I tried looking at MSD's site and I was using these instructions http://www.msdignition.com/pdf/6%20series/pdf9.pdf , but it doesn't look like those work. Still no spark or fuel. I'm confused...
