TFI-I Equipped Engines only

Remove distributor from engine and remove ignition module from distributor housing. Inspect distributor ground screw, pick-up coil assembly wires and terminals. Measure pick-up coil resistance with ohmmeter leads connected to points. See Fig 1.

Fig 1: Pick-Up Coil Assembly Resistance Test Points Pick-up coil resistance should be 650-1300 ohms.
If resistance was 650-1300 ohms, pick-up coil assembly is okay, replace ignition module. If resistance was less than 650 or greater than 1300 ohms, ignition module is okay, replace pick-up coil assembly. Reinstall ignition module on distributor housing and install distributor on engine.
