Ignition control module location on a 1992 Ford Truck F150 1/2 ton P/U 2WD 4.9L FI 6cyl


I believe it is mounted on the distributor.. It is bolted onto the distributor with two small screws. It is called a TFI Module (Thick Film Integrated) module. It is gray in color and about 1 inch wide maybe 3 inches long with a connector on one end.

How do I repalce ignition module on 1991 F150 inline 6 cylinder 2 wheel drive


  1. Remove the distributor cap from the distributor, and set it aside (spark plug wires still connected).
  2. Disconnect the harness connector.
  3. Remove the distributor.
  4. Remove the TFI module retaining screws.
  5. To disengage the TFI module's terminals from the distributor base connector, pull the right side of the module down the distributor mounting flange and then back up. Carefully pull the module toward the flange and away from the distributor.
  6. Coat the TFI module baseplate with a thin layer of silicone grease (FD7AZ-19A331-A or its equivalent).
  7. Place the TFI module on the distributor base mounting flange. Position the module assembly toward the distributor bowl and carefully engage the distributor connector pins. Install and torque the two TFI module retaining screws to 9-16 inch lbs.
  8. Install the distributor assembly.
  9. Install the distributor cap and check the engine timing.

Sorry I don't do text, because I don't want spam either... The most likely cause of your problem is a bad TFI (ignition) module. All of the engines used in Ford trucks in 1991 used the TFI modules. Some were distributor-mounted modules and some were fender-mounted modules. I cannot tell you where yours is actually located, because you did not bother to mention engine size. (Nice-to-know information - it helps a little if we know what we are working on) Anyway, That is the most likely cause of a no-spark condition. In fact, It has been so common with the Ford engines that Ford ended up settling in a class-action law suit due to the TFI modules repeatedly leaving people stranded. I personally had a Ford Ranger - replaced the TFI module about 6 times in the 7 years that I owned it...used to keep a spare in the glove box.

Turns over , gas to carb but no spark? replaced coil. 1982 Ford 2.3 liter engine


1980's Fords were notorious for the "Thick Film Ignition" (TFI) modules going bad. They were so bad in fact, that there was a class-action law suit filed against Ford for this issue. If you are sure that your distributor cap, rotor and wires are in good condition, then I would try replacing the TFI module. It is screwed to the side of the distributor. A special socket tool can be purchaced at your local parts supplier for this purpose. The screws go way inside the body of the TFI module and standard sockets will not fit into the hole far enough to get onto the head of the screw. It is not real expensive. You are looking at maybe less than $80 for the TFI module and the tool to install it with.

How do i wire up an electronic ignition in a 1970 Ford F100 that was originally on a points system?


Hey! One of my favorite projects here. The simplest way to go. First you need to make sure the wireing harness is setup for TFI system. It should have a couple big connectors by the driver side fender well in the engine bay. You will need a TFI module. Next you can use the original distributor or buy a new electronic one. If you use the original you have to buy a new stator and cap. I also recomend a new coil and preferably get rid of the balast resistor. This should complete your project.

My 1989 ford F150 lariat cut off on me while I was going down the road. It is getting fuel but there is no spark coming from the coil wire. What could be the problem?


Has the truck had a tune up?
Check the TFI module or replace it should be bolted to bottom of distributor. Replace cap, wires, plugs, rotor button and coil.
(TFI modules during the 80's and 90's failed when it got hot.)
