You are watching: 1990 ford f150 ignition control module location
NOTE: This test in this tutorial will only help you in a ‘cranks yet does not start due to a absence of spark’ problem.
So then, before beginning the tests, it"s critical that you have actually checked and also verified the there"s NO SPARK existing at the ignition coil. Why? Well, because if the ignition coil is sparking, it would be a clean indication the it and the ignition manage module and also the crankshaft place sensor (PIP sensor) are working.
This article applies to both the Gray fancy ignition regulate module and the Black colored ignition manage module.
The Gray fancy ignition regulate module is dubbed the Push begin Module and the Black colored ignition regulate module is called the Computer managed Dwell Module. This ignition control modules space not interchangeable.

To test Ford Coil-On-Plug Ignition Coils (4.6L and 5.4L V8 engines), walk here: Ford Coil-On-Plug (COP) Ignition Coil Tests.

How go The Ignition control Module Work?
Here"s a small background info to assist you diagnose this no spark condition. In a nutshell, once the system is working properly, in ~ CRANK-UP and also at every engine speeds, the ignition control module controls the ignition coil.
How? This is mostly done thru" the profile Ignition Pickup sensor signal i beg your pardon is got by the ignition regulate module (and also the ECM).
The ignition control module (ICM) top top receiving this signal, starts convert the ignition coil"s ground ON and also OFF. Together you may already know, it"s this action that renders the ignition coil spark away.
The profile Ignition Pickup sensor signal (more frequently 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 file Ignition Pickup sensor is a hall Effect form crankshaft place sensor and also produces a digital (On/Off) signal that can 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 carry out I need For The Ignition Module Test?
There space several ways to test this ignition manage module. An oscilloscope is the best way to check all of the input and also output signals but it"s no the only way. I"ll show you just how.
Anyway, if girlfriend have access to an oscilloscope, ns have consisted of photos the what the waveforms must look like. Whether you use a multimeter or an 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 an analog multimeter.Repair manual.This is not an absolute must but you might need the for everything other details this post does no cover or provide.Helper.To help you crank the engine when you observe the LED irradiate (or test light or multimeter).
By the way, girlfriend don"t require an automotive scan device for any type of of this tests.
We"ll very first check for the basics choose battery voltage and engine Ground come the ignition manage module.
Then we"ll check the ignition coil convert signal the the signal generates in action and indigenous the results you get you"ll have the ability to pinpoint the problem to the ignition regulate module (ICM) or the ignition coil or the file Ignition Pickup (PIP) sensor or totally eliminate these together the reason of the no begin condition.
IMPORTANT: every one of the tests space ON car TESTS, carry out not eliminate the ignition control module assembly from the car (all of the figures present the module assembly turn off of the car but this is simply for illustration functions only). Also, the battery need to be in a totally charged condition 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 also Save
If friend find, after experimentation the experimentation the ignition module your test results indicate a negative one climate take a look at the links below. Ns think they"ll conserve you part bucks (especially on the original Motorcraft ignition module):
NOTE: If you"re not certain if the above ICM right your specific Ford don"t worry. Once you acquire to the site, they"ll make sure it"s the appropriate one, if not, they"ll uncover you the right one.
If your test results suggest that the PIP sensor is negative (which is situated inside the distributor), the ideal option for replacing it is to buy the whole distributor.

Why? Because committed tools are required to disassemble the distributor to change the PIP sensor. I recommend buying the distributor native a recognized automotive brand -AVOID purchase A CHINESE KNOCK-OFF DISTRIBUTOR!
Known great automotive brand are: Cardone, Autoline, WAI Global, Spectra Premium.
