In this quick test you"ll be able to pinpoint the problem to the ignition control module or the ignition coil or the file Ignition Pickup sensor (PIP sensor) in 4 easy test steps.

NOTE: This exam in this tutorial will certainly only aid you in a ‘cranks yet does no start as result of a lack of spark’ problem.

So then, before beginning the tests, it"s an essential that you have checked and also verified that there"s NO SPARK present at the ignition coil. Why? Well, due to the fact that if the ignition coil is sparking, it would certainly be a clean indication the it and also the ignition regulate module and the crankshaft place sensor (PIP sensor) are working.

This article uses to both the Gray colored ignition control module and the Black fancy ignition regulate module.

The Gray colored ignition manage module is referred to as the Push begin Module and also the Black colored ignition regulate module is called the Computer controlled Dwell Module. This ignition regulate modules space not interchangeable.

How walk The Ignition regulate Module Work?

Here"s a little background info to assist you diagnose this no spark condition. In a nutshell, once the device is functioning properly, in ~ CRANK-UP and at all engine speeds, the ignition regulate module controls the ignition coil.

How? This is mainly done thru" the profile Ignition Pickup sensor signal i m sorry is received by the ignition control module (and additionally the ECM).

The ignition manage module (ICM) ~ above receiving this signal, starts switching the ignition coil"s soil ON and also OFF. Together you may already know, it"s this action that renders the ignition coil spark away.


The file Ignition Pickup sensor signal (more frequently called the PIP signal) is critical for the ignition regulate module to begin sparking the ignition coil at start UP and also at all engine speeds.

The file Ignition Pickup sensor is a hall Effect type crankshaft position sensor and produces a digital (On/Off) signal that deserve to be seen v an LED or an oscilloscope.

On one oscilloscope, the produces a digital square waveform. This sensor is situated in the distributor.

What Tools do I need For The Ignition Module Test?

There space several ways to check this ignition manage module. One oscilloscope is the best way to check all of the input and output signal but it"s not the only way. I"ll show you simply how.

Anyway, if friend have accessibility to an oscilloscope, ns have included photos of what the waveforms must look like. Whether you usage a multimeter or one oscilloscope, you"ll have the ability to successfully diagnose this no-start condition! So, here"s the straightforward list:

An LED light.Automotive 12 Volt check light.Multimeter.A cheapie one will do, whether its digital or one analog multimeter.Repair manual.This is no an pure must but you might need it for whatever other information this write-up does no cover or provide.Helper.To assist you crank the engine when you observe the LED irradiate (or check light or multimeter).

By the way, girlfriend don"t require an automotive scan tool for any type of of these tests.

We"ll an initial check for the basics favor battery voltage and engine Ground to the ignition manage module.

Then we"ll check the ignition coil convert signal the the signal generates in action and from the outcomes you obtain you"ll be able to pinpoint the trouble to the ignition control module (ICM) or the ignition coil or the profile Ignition Pickup (PIP) sensor or fully eliminate these as the cause of the no start condition.

IMPORTANT: every one of the tests room ON auto TESTS, do not remove the ignition manage module assembly indigenous the automobile (all the the figures present the module assembly turn off of the auto but this is just for illustration functions only). Also, the battery must be in a completely charged condition for every tests in this article. And also lastly, this fast Test only tests for a no-spark no-start condition.

Where to Buy The Ignition Module and Save

If girlfriend find, after testing the experimentation the ignition module your test results indicate a bad one climate take a look in ~ the web links below. I think they"ll conserve you part bucks (especially top top the original Motorcraft ignition module):


NOTE: If you"re not sure if the above ICM to the right your details Ford don"t worry. As soon as you obtain to the site, they"ll make sure it"s the ideal one, if not, they"ll discover you the appropriate one.

If your test results show that the PIP sensor is bad (which is located inside the distributor), the finest option because that replacing that is buying the entire distributor.

Why? Because committed tools are needed to disassemble the distributor to replace the PIP sensor. Ns recommend purchase the distributor indigenous a known automotive brand -AVOID to buy A CHINESE KNOCK-OFF DISTRIBUTOR!

Known an excellent automotive brands are: Cardone, Autoline, WAI Global, Spectra Premium.
