Ignition System - TFI-IV: Description

All EEC-IV controlled engines use the TFI-IV ignition system. The TFI-IV distributor is a gear driven, die cast unit. A Hall Effect stator assembly is used to trigger the ignition coil. This distributor does not use conventional centrifugal/vacuum advance mechanisms. See Figure or Figure. On models with 3.8L engines, a "closed bowl" distributor is used. The TFI ignition module is mounted on the cowl behind the engine (Continental, Sable and Taurus) or the radiator crossmember (Cougar and Thunderbird). On all others, the TFI ignition module is integrally mounted on base of distributor.

The TFI ignition module used on manual transaxle equipped vehicles features a push start mode. This feature allows vehicle to be push started if necessary. An "E" core ignition coil is used.
