Want this question answered?
I just went through removing the Ignition Control Module and Coils for testing. There are two coils which sit on top of the ICM. One is responsible for firing cylinders 1-4 and the second is responsible for firing cylinders 2-3. The 1993 Cavalier has a Direct Ignition System (DIS) or Electronic Ignition. 1 12... I put 12 on mine and got 27% increased gas mileage which in 2 months offset the cost2 coils if it dose not hava a disterber cap
There is a total of 4 ignition coils.
It's printed on the intake manifold, just above the ignition coils.
Check to make sure there is power going to your coils from your ignition switch.

Check the ignition coils and the crank sensor for the Yukon. Either one of these could be bad and cause the problem.

Everything in your car will eventually stop working. Mileage temperature and driving conditions all play a part its just a normal thing that happens.
The easiest way to test ignition coils on a 1992 Mustang 2.3 is to use an ohmmeter on the leads going into the coils.
The ignition module is located under the three ignition coils. The same bolts that hold the coils in place also retain the module to the mounting bracket. To find the coils, follow the ignition wires from the front of the engine to where they attach at the rear. The wires clip to the coils.
Disconnect the battery. Remove the ignition coils. Remove the ignition control module that was under the coils, and replace it.
