I have an older 70's block with 91 heads and a TPI unit from a GTA. The motor is going into a 1972 4x4 Blazer but if any board knows about TPI motors it will be you guys. The problem i'm having is i'm not getting any output from the coil. I am using a painless wiring harness with a seperate coil distributer. I DO have power at the coil and I have check the distributer and it seems fine. If you guys have any thoughts please let me know. Thanks

I would check the module, pick-up and coil. If you don't have a multimeter to do it with Autozone will test them for you. Also if you put an ignition box on the truck make sure you have all the wires hooked up correctly.
