The TFI-IV module supplies voltage to the Profile Ignition Pick-up (PIP) sensor, which sends the crankshaft position information to the TFI-IV module. The TFI-IV module then sends this information to the EEC-IV module, which determines the spark timing and sends an electronic signal to the TFI-IV ignition module to turn off the coil and produce a spark to fire the spark plug.

Pull the small wire off the starter solenoid so engine will not crank. Have an assistant try to crank the engine. There should be voltage at "TFI POWER RUN, TFI POWER CRANK (START SIGNAL IN), and TACH IDM (COIL NEGATIVE)" terminals. If there is not voltages present, there is a possible wiring problem.
