Is there a spark in the ignition module?
There is no spark coming out of any of the ignition coils sitting on top of the ignition module. You may have taken your ignition control module (ICM) to Auto Zone to test it and the friendly boys in orange say it’s good, yet the vehicle will not start (all major auto parts stores such as O’Reilly, Pepboys, etc., test ignition modules for free).
What are the symptoms of an ignition failure?
Here are some of the most common failure symptoms: The car (or minivan or Isuzu SUV) cranks but does not start. There is no spark coming out of any of the ignition coils sitting on top of the ignition module.
How does the ignition control module work in a car?
Basic Theory: How The Ignition Control Module Works. In a nutshell, the ignition control module’s job is to create a Switching signal for the ignition coils that are sitting on top of it. It’s this Switching signal that makes the ignition coils create spark.
How to test the ignition module and crank sensor?
So, if you’re driving a Chevy, a Buick, a Pontiac, or an Oldsmobile with either one of these engines, not forgetting the Isuzu Rodeo or Trooper, this ‘How To Test The Ignition Module’ and 7X (3X) article applies. There are two other articles that may help:
How does the ignition module work on a 2.3L engine?
The ignition module is tasked with activating the two ignition coil packs that feed the 8 spark plugs that the 2.3L 4 cylinder engine is equipped with. Now, I won’t go into minute technical detail as to how everything works in this ignition system. Just the basics that you and I need to get to the bottom of the problem.
Why is my ignition module not working properly?
It’s also possible the circuits may be critically damaged by overheating if the problem is not addressed after the first or second occurrence. If you cannot start the car, you need to test the ignition control module using a light timing tester to check the output of the module.
Where are the connectors on the ignition module?
The ignition control module has two connectors. Looking down at the ignition module (with the ignition module still bolted to the intake manifold), you’ll notice that the ignition control module has a top connector and a bottom connector. In the pin out charts below is a brief job description of what each wire does.
Where are ignition coil packs on GM 3.8L?
If you do need to test just the ignition coil packs sitting on top of the ignition control module (ICM), here’s the article for you: How To Test The GM 3.8L V6 Ignition Coil Packs. For a list of all of the 3.8L articles in this site, check out the index: GM 3.8L Index Of Articles.
There is no spark coming out of any of the ignition coils sitting on top of the ignition module.

What to do if your ignition control module is not working?
Place the spark plug on a metal surface on the engine. Crank the engine and check for a spark at the old spark plug. No spark on the plug indicates an ignition problem.
How does the crank sensor control the ignition module?
The ignition module starts to turn On and Off the ignition coils in their proper firing order to create spark, after the crank signal arrives. This On/Off action is the Switching signal referred to above. Under 400 RPM’s, the ignition control module controls spark timing without the help of the fuel injection computer.
Why does my 2004 Grand Am GT 3400 not start?
