I had to bypass mine b/c I hadn't hooked it up on the tranny. That was keeping me from spinning the motor over.

There is a wire that would have been in the C100 connector that is pink that gives power to the coil when the ignition is turned on, I would verify that you have 12v to the plugs going to the coilpacks.

If it won't fire after it spins over, make sure the 12v wire you are using for the coils has 12v DURING cranking. The one to the coil in my Painless kit wasn't 12v during cranking for some reason, so check that out as well.

Double check your fuses in the fuse block. I had a blown fuse and I swore I checked all of them twice. I also had a bad ground from the motor to the car itself.

And there should be two sets of wires going to the PCM with power, one ignition on, and one bat all the time. I was chasing the same problem with my LT1 and found out that I didn't have one hooked up. I had coil power, but nothing else

Have you tried to get a scan tool to connect to the computer to see if any readings are there?
