Why are two towers from the same coil pack not firing?
Why are two towers from the same coil pack not firing?
And so when you have 2 towers from the same coil pack not firing spark, it’s usually due to one of two reasons: 1.) the coil pack is bad or 2.) the ignition control module (ICM) has fried internally and is not activating that specific ignition coil within the coil pack (although it will activate the others).
What is the wiring diagram for a Ford Ranger?
Wiring Diagram: The following wiring diagram may be of help: 1992-1994 2.3L Ford Ranger Ignition System Wiring Diagram. * Your specific Ford vehicle may have different colors. * Your specific Ford vehicle may have different colors.
Can a bad ignition module cause a misfire?
The ignition module has failed. Misfire due to a bad ignition module. Since the ICM isn’t cheap and replacing the crank sensor is labor intensive (you’ve got to remove the timing belt), testing the ICM and crank sensor, on your 2.3L Ford Ranger or Mustang (or B2300), becomes a must!

How many spark plugs are in a coil pack?
To understand this phenomena (two coil pack towers from the same coil pack not sparking), you and I need to know that each coil pack fires spark to 2 spark plugs at the exact same time (this is known as a Waste Spark ignition system). Here are the specifics: Each coil pack feeds 4 spark plugs.
How are cylinders 2 and 3 of the ignition module paired?
Towers that feed spark to cylinders #2 and #3 are ‘Paired’. Towers that feed spark to cylinders #1 and #4 are ‘Paired’. NOTE: If you have no spark from any other towers that are not ‘Paired’ (like No Spark from Cyl #1 and #3), then the ignition control module is not at fault and this tutorial won’t help you.
Why is the ignition module not firing spark plugs?
This tells you that the ignition control module (ICM) is not activating the ignition coil (within the coil pack) that’s responsible for firing spark to exhaust spark plugs #1 and #4. Replace the ignition control module.
Why is the crank sensor on my Ford Ranger not working?
Without voltage, in this wire, the ignition control module, the crankshaft position sensor and both coil packs won’t work. Restoring Power to this circuit should solve your no-spark no-start condition on your 2.3L Ford Mustang or 2.3L Ford Ranger (2.3L Mazda B2300).
