How do I replace the ignition module on a 1989 Oldsmobile Cutlass?

Are you getting power to the ignition module? It could be your ignition switch. I once had a 1993 Buick that would die intermittently with no rhyme or reason. Turned out to be the ignition switch. And my daughter has a 1995 Camaro that when you would start it...sometimes it would be a 2 cylinder, sometimes a 4 cylinder, and other times a 6. Still not sure how that one worked, but it was the ignition switch that is located on top of the steering column down by the firewall.

Hi David,

Here is a good explanation. 360 Look Into the GM 60 3 1L Engine Underhood Service . Repair Pal is a forum for questions like yours with many good answers, Oldsmobile Cutlass Ciera Repair Problems Cost and Maintenance. But yes to your answer, isolate, and eliminate. I always like you learn more so the out of pocket becomes less. Fare. Well.

The ignition module is located under the coil packs on the v-6 engine.
That is where the spark plug wires go to the spark plugs . When you remove the coil packs ,the flat peice is themodule.When you remove the module , the crankshaft sensor is sometimes located there ,and that also should be changed

replace the crankshaft position sensor, it will cure the problem.

What you should do when it stalls is check to see if your loosing spark at the plugs.If you are then you probably have a bad ignition module.It is located in the rear of the motor.The ignition coils are mounted on it.One other possibility is the pcm.It is located under the dash on the passengers side.You can get a used one at most salvage yards.You will need to get the number from the old pcm.You will also have to remove the old prom from the old pcm and install it in the one you get for replacement.Hope this helps.Good luck.

89 cierra? It should be DIS ignition so you can't have the timing too high. You said it has fuel and spark. Fuel pressure and injection pulse. Does it try to start if you spray carb cleaner into it?

most common cause of no spark is the ignition module located under the coil

Replace the oil pressure switch next to the oil filter. When you turn on the ignition the fuel pump runs to prime the system then turns off. Then the oil pressure switch runs the fuel pump to keep the engine running. To test, connect the fuel pump test wire(located at the left front wheel well) to the battery. This will bypass the pressure switch and the engine should run.
