In this rapid test you"ll be able to pinpoint the difficulty to the ignition control module or the ignition coil or the file Ignition Pickup sensor (PIP sensor) in four easy check steps.

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

So then, before starting the tests, it"s critical that you have checked and also verified the there"s NO SPARK current at the ignition coil. Why? Well, since if the ignition coil is sparking, it would be a clear indication the it and the ignition regulate module and the crankshaft position sensor (PIP sensor) room working.

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

The Gray fancy ignition manage module is dubbed the Push begin Module and the Black colored ignition regulate module is referred to as the Computer regulated Dwell Module. This ignition manage modules are not interchangeable.

How walk The Ignition control Module Work?

Here"s a small background info to assist you diagnose this no spark condition. In a nutshell, once the mechanism is functioning properly, at CRANK-UP and also at all engine speeds, the ignition control module controls the ignition coil.

How? This is primarily done thru" the profile Ignition Pickup sensor signal i m sorry is obtained by the ignition regulate module (and also the ECM).

The ignition regulate module (ICM) top top receiving this signal, starts switching the ignition coil"s ground ON and OFF. Together you may currently know, it"s this activity that provides the ignition coil spark away.


The profile Ignition Pickup sensor signal (more typically called the PIP signal) is vital for the ignition control module to begin sparking the ignition coil at start UP and also at every engine speeds.

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

On an oscilloscope, that produces a digital square waveform. This sensor is located in the distributor.

What Tools perform I need For The Ignition Module Test?

There space several methods to check this ignition control module. One oscilloscope is the best means to check every one of the input and also output signal but it"s not the only way. I"ll display you just how.

Anyway, if girlfriend have accessibility to one oscilloscope, i have consisted of photos that what the waveforms need to look like. Whether you usage a multimeter or an oscilloscope, you"ll have the ability to successfully diagnose this no-start condition! So, here"s the basic list:

An LED light.Automotive 12 Volt test light.Multimeter.A cheapie one will certainly do, whether its digital or an analog multimeter.Repair manual.This is not an pure must however you might need the for every little thing other details this write-up does no cover or provide.Helper.To assist you crank the engine if you watch the LED light (or test light or multimeter).

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

We"ll first check for the basics prefer battery voltage and also engine Ground come the ignition regulate module.

Then we"ll check the ignition coil convert signal the the signal generates in action and indigenous the outcomes you acquire you"ll be able to pinpoint the problem to the ignition control module (ICM) or the ignition coil or the file Ignition Pickup (PIP) sensor or totally eliminate these together the reason of the no start condition.

IMPORTANT: all of the tests are ON vehicle TESTS, carry out not remove the ignition regulate module assembly native the vehicle (all that the figures display the module assembly off of the vehicle but this is simply for illustration functions only). Also, the battery need to be in a totally charged problem for every tests in this article. And also lastly, this fast Test just tests for a no-spark no-start condition.

Where to Buy The Ignition Module and Save

If girlfriend find, after experimentation the experimentation the ignition module your test results show a poor one then take a look at the web links below. Ns think they"ll save you part bucks (especially on the original Motorcraft ignition module):


NOTE: If you"re not sure if the over ICM to the right your details Ford don"t worry. Once you acquire to the site, they"ll make sure it"s the ideal one, if not, they"ll uncover you the ideal one.

If your test results suggest that the PIP sensor is poor (which is located inside the distributor), the ideal option because that replacing the is purchase the whole distributor.

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

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