In this rapid test you"ll have the ability to pinpoint the problem to the ignition regulate module or the ignition coil or the profile Ignition Pickup sensor (PIP sensor) in four easy test steps.

NOTE: This tests in this tutorial will only assist you in a ‘cranks but does no start because of a absence of spark’ problem.

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

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

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

How walk The Ignition regulate Module Work?

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

How? This is mainly done thru" the file Ignition Pickup sensor signal which is got by the ignition regulate module (and additionally the ECM).

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


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

The profile Ignition Pickup sensor is a hall Effect kind crankshaft place sensor and also produces a digital (On/Off) signal that have the right 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 regulate module. An oscilloscope is the best method to check every one of the input and also output signals but it"s not the only way. I"ll display you simply how.

Anyway, if you have access to one oscilloscope, ns have contained photos of what the waveforms have to look like. Even if it is you use a multimeter or an oscilloscope, you"ll be able to successfully diagnose this no-start condition! So, here"s the simple list:

An LED light.Automotive 12 Volt check light.Multimeter.A cheapie one will do, even if it is its digital or one analog multimeter.Repair manual.This is not an absolute must however you may need the for every little thing other information this article does no cover or provide.Helper.To aid you crank the engine if you observe the LED irradiate (or check light or multimeter).

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

We"ll an initial check for the basics like battery voltage and also engine Ground come the ignition regulate module.

Then we"ll test the ignition coil convert signal that the signal generates in action and native the outcomes you obtain you"ll be able to pinpoint the problem to the ignition regulate module (ICM) or the ignition coil or the file Ignition Pickup (PIP) sensor or fully eliminate these together the reason of the no begin condition.

IMPORTANT: every one of the tests space ON vehicle TESTS, perform not eliminate the ignition control module assembly indigenous the automobile (all that the figures present the module assembly off of the vehicle but this is simply for illustration functions only). Also, the battery need to be in a fully charged condition for every tests in this article. And also lastly, this rapid Test only tests because that a no-spark no-start condition.

Where to Buy The Ignition Module and Save

If friend find, after experimentation the testing the ignition module her test results show a negative one climate take a look at the links below. Ns think they"ll save you some bucks (especially top top the original Motorcraft ignition module):


NOTE: If you"re not sure if the over ICM fit your specific Ford don"t worry. Once you obtain to the site, they"ll make certain it"s the right one, if not, they"ll uncover you the best one.

If your test results show that the PIP sensor is bad (which is situated inside the distributor), the ideal option for replacing that is purchase the entire distributor.

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

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