Well, the TFI tells the coil when to fire from the pulses from the PIP in the distributor. I would test the TFI first to see if it is good.

Test light from coil neg to ground. Key on. light will light. Crank engine. Light should flash. If no flash on crank, TFI is not firing coil. No flash = TFI or PIP failure. Try this with the SPOUT connector disconnected also.
