Vehicle cranks but will not start no fire


Common Fox Mustang issue related to this condition would be a faulty coil,ignition connection under steering wheel melted,faulty or the TFI Module on the Dizzy. I would start with the TFI 9 times out of 10 this is the culprit. Be sure to replce it with a motorcraft as Ive had bad experinces with aftermarket TFI modules right out of the box. I've attached a photo of the TFI module below. Good Luck Ryan MN

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.

No spark


I would check the fuses and relay for the EEC IV. You probably have a bad TFI ignition control module, the gray box bolted to the side of the distributor. Auto Zone should be able to test it. Also, check the pick up coil inside the distributor.

it is mounted on the side of the ignition distributor body, here is a picture, u should also change the Stator inside the distributor, this requires you remove the distributor from the engine and then drive out the roll pin that holds the drive gear on, this is not for the do it yourself-er

1995 ford taurus 3.0l v6 wagon no spark.


Listen TFI module is more than likely the problem change it. TFI module controls spark and timing and fuel. Keep one with you in the car. The module is getting hot and not working right.
