What is a TFI module?
What is a TFI module?
The TFI module regulates the electrical current that fires the air-fuel mixture in each of the engine’s cylinders. To reduce costs, Ford installed the TFI on the distributor, one of the hottest locations under the hood.
Where is the spout connector on a Bronco?
Check the Spark Output (SPOUT) connector near the Ignition Control Module (ICM) at the rear of driver side fender apron (near hood hinge) to see if the SPOUT connector is missing or is making poor contact to the connector. 2.
What should ignition timing be with the spout connector removed?
If the SPOUT connector & connection appear to be in good condition, install a timing light onto #1 spark plug wire and check for timing advance at idle with the engine running. Ignition timing should indicate 10 degrees BTDC with the SPOUT connector removed but timing should then advance when the connector is plugged back in. 3.
What does spout signal mean on Ford TFI?
The coil is turned off, thereby firing, whenever a rising edge of a SPark OUTput (SPOUT) signal is received. The SPOUT signal is generated by the PCM, and provides spark timing information to the TFI. During the push start mode, the SPOUT signal only indicates the timing for coil firing; the falling edge of the SPOUT signal is ignored.
Where are the diagnostic connectors on a Ford?
This connector is usually located under the driver side dash panel. Diagnostic Link Connector No. 73 Locations: Left-hand side of firewall. Near or in the fuse box, or near the battery. Next to the airflow meter or battery. Diagnostic Link Connector No. 26 Locations: Left-hand side of firewall.

What is the spout signal on a Ford EEC IV?
Here is a picture of SPOUT (Spark Output signal) wire that was grounding out. The yellow spark output signal wire is without a section of insulation. This section happens to run through a shield ground that provided a convenient ground source for the SPOUT signal.
What are the computer codes for Ford TFI-IV?
If your TFI is failing from heat, it can give off computer codes 14 (PIP) and 18 (SPOUT). The TFI-IV distributor ignition system consists of the following components: The distributor ignition system designed by Ford has two distinct configurations.
What does push start mode on Ford EEC IV do?
The push start mode allows for increased dwell, or coil on time, when starting the engine. During this mode, the TFI determines when to turn on the ignition coil based on engine speed information. The coil is turned off, thereby firing, whenever a rising edge of a SPark OUTput (SPOUT) signal is received.
