3.8L (FWD Only)
- Separate harness connector from distributor. Inspect for dirt, corrosion or damage. Measure resistance between terminals No. 1 and 5 on distributor side of connector. Resistance should be less than 5 ohms.
- If resistance is less than 5 ohms, proceed to step 3). If resistance is more than 5 ohms, replace stator.
- Measure resistance between stator connector terminal No. 2 and distributor base. Resistance should be less than 5 ohms.
- If resistance is less than 5 ohms, check terminals No. 1 ("PIP-A") and No. 6 ("IGN GND") signal wires for continuity to EEC module. If continuity is not present, repair open circuit in wires. If resistance is more than 5 ohms, replace stator.

- Measure resistance between terminal No. 6 and base of distributor. If resistance is less than one ohm, service wiring between connector and TFI module and between connector and distributor ground circuit.
- If resistance is more than one ohm, inspect stator retaining screws in distributor bowl. If retaining screws are tight and not corroded, replace stator. If screws are loose or corroded, repair as needed. Repeat step 5).
- With ignition off, disconnect TFI harness connector from TFI module. Reconnect harness connector to distributor. Using voltmeter, attach negative lead to distributor base. Attach positive lead to TFI harness connector terminal No. 5 ("PIP-B" to Module).
- Crank engine while noting voltage reading. If voltage is between 3-6 volts, stator is okay, replace TFI module. If voltage is not between 3-6 volts, replace stator.
