United States delivery.In a GM car or truck with a V8 engine, the ignition control module also known as the ICM is hiding under the distributor cap.

Chevy trucks, GMC trucksor any General Motors vehicle with this type of eight-cylinder engine will be the same. If you drive a different vehicle, the process will be very similar. First, get a new ignition control module for your vehicle.

These can be found both in physical stores and junkyards. Ignition control modules can also be purchased online. The first thing that needs to be removed to access the distributor is the air cleaner assembly. To remove this, there are a couple of connections that need to come off first.

There is a breather hose attached underneath toward the front of the engine compartment. This pulls off easily.

Next, remove the larger preheat tube from the bottom of the air cleaner. This should also pull right off, although it might be a little stuck from being on there so long. Remove the wing nut from the top of the air cleaner and take off the cover. With the air cleaner element removed, you may see a couple of small bolts attaching the air cleaner assembly.

If you're not sure, give it a firm tug upward and, if it doesn't pop off or at least shift a lot, you need to remove some bolts first. With the air filter assembly removed, you can see the spark plug wires and distributor cap.

You will need to remove the distributor cap to access the ignition control module, but do not remove all of those plug wires! It's not a necessary step and there's always a real chance that you'll screw up the firing order when you reinstall them and have to go back to square one.

Leaving them attached to the distributor cap is a much easier move.

Remove the two bolts that attach the cap to the distributor and move the cap to the side.This page is for personal, non-commercial use.

Modern vehicles are equipped with a variety of electronic sensors and modules to control the various engine functions necessary for the vehicle to run. One of these components is the electronic spark control module, commonly referred to as the ESC module, or the ignition module.

One of the specific functions of the ESC module is to advance or retard the timing of the ignition system, depending on the operation conditions. Under heavy load, the module will advance the timing to increase power and will retard it at low throttle and cruising speeds in order to maximize efficiency. The ESC module makes these changes automatically and smoothly, almost to the point where they are virtually unnoticeable to the driver.

As the ESC module plays an important role in the operation of the engine, any problems with it can cause issues with the drivability and performance of the vehicle. Usually a bad or failing ESC module will produce a few symptoms that can alert the driver of a potential issue that should be serviced.

One of the first symptoms of a problem with the ignition module are engine performance issues. If the ignition module fails or has any problems it can lead to performance issues with the vehicle, such as misfireshesitationloss of powerand even reduced fuel economy.

Another symptom of a problematic ESC module is the engine stalling. A faulty module may cause the engine to suddenly stall and be unable to start again. Sometimes the engine can still be restarted after a short period of time, usually after the module has been allowed to cool off.

Another common symptom of a faulty ESC module is a no start, or no spark condition. The ESC module is one of the components that directly controls engine spark, so if it fails, it can leave the vehicle without spark. A vehicle without spark may still crank, but will not be able to start or run.

The ESC module is one of the most important components found on many modern ignition systems, and without it most vehicles will not run properly. If you suspect that your ESC module may be having an issue, have the vehicle inspected by a professional technician, such as one from YourMechanic, to determine if your vehicle needs an electronic spark control replacement.

The complaint is the engine cranks normally, but does not start.

The cause of an ignition control module failure is often associated with age and damage from heat buildup.

The correction for this issue becomes the replacement of the failed component. Here in this brief article we'll talk about three popular generations of control modules known for a high failure rate. This article focuses on General Motors automobiles from the last 30 years. We start on covering vehicles from the mids and progress through the model year.

When I say high and dry I'm talking about a vehicle that cranks around, but will not fire up. Most of the original modules installed in Chevrolet distributors from the mids through the mids shared the same solid-state design. General Motors designed them to last for the life of the vehicle. However the 4. It's not uncommon the find a Chevrolet Silverado pickup from the early 90s with more thanmiles on the 5.

The same can be said for the Chevrolet Blazer or S pickup truck that carries the 4. These engines need ignition modules before they head to the junkyard.

On a technical note, make sure you apply dielectric grease to the heat sink before you install the new part. We have more on that below. These old distributors let air in through the bottom and vent it through the top of the distributor cap. If these become clogged corrosion and heat buildup can cook the new module. In General Motors redesign the ignition module discussed above. They used it on about 10 years worth of vehicles.

With that said, these parts didn't hold up as well or as long as the ignition modules from the previous generation. These parts found their way into the same V-8 and V-6 engines mentioned above. However, they now call them Vortec motors. Some popular vehicles with high sales figures carried these types of ignition modules. This also includes the pickup trucks and cargo vans.

What's interesting about this common ignition module failure is the way it goes out. When the second generation modules go bad the vehicle starts up and runs good until it gets hot. After the engine cools down the vehicle might restart and run fine until it gets hot again. This cycle happens over and over again until you replace the component. Intermittent malfunctions become hard to find, but the way this module fails is common knowledge around experienced mechanics.

Sidebar: In some cases the Vortec plastic distributor fails before the ignition module. In the early 90s General Motors started to do away with the distributor, cap and rotor we all loved since the turn-of-the-century.

GM decided they didn't need all those moving parts.All Rights Reserved. The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. Hottest Questions. Previously Viewed. Unanswered Questions.
