It depends on what engine yu have but on a lot of them it is under the coils. If your car has a dist it is inside.
Inside that flat cover on the very top of the engine.There are 2 inside that plastic housing,after you remove that assembly.
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
you take off the ignition coils on top of the valve cover there are 4 bolts you have to take off then pop off the ignition coil
On a 2.8l v6 it is at the front of the engine behind the ignition coils.
it is what the coils are mounted too.
There is 1 per cylinder.
Unplug the two wire connectors located above the ignition coils (one has two wires the other larger one has three wires, usually) remove the two ignition coils (4 X 5.5mm bolts). The module is located under the two coils (the coils plug directly into the module).
i have an 89 and it ran like it was on 5 cylinders.replaced 1 of 3 coils and fixed it yours might be diffrent tiigghhtt ssqueeezeee.
It's a tough call, but the one we did a couple of months ago, had a bad computer. It would run good for a few minutes, and then start running rough, as if there was a load being placed on the engine. Then of course, it would cough and die. Have you checked the ignition module? It's the plate that the coils sit on, that has the wires connected to it. Most junk yards sell the complete coil pack (mount, ignition module and both coils) for 25-35.00 $.
There is a total of 4 ignition coils.
