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. 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 & Taurus) or the radiator crossmember (Cougar/Thunderbird). On all others, the TFI ignition module is integrally mounted in the distributor. A Hall Effect stator assembly replaces the coil stator. This distributor does not use conventional centrifugal/vacuum advance mechanisms. See Figure.

The TFI ignition module is contained in molded thermoplastic and is mounted on base of distributor. See Figure. 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.
