Question about 1995 Buick LeSabre
My car started acting funny so we changed the 1&4 coil pack and the tension pully...even with the 1&4 coil pack replaced they still arent firing. i was told it was the ignition module..i need to know where the ignition module is located and how to install a new one. if u can help me it would be greatly appreciated! thank you
The ignition module is under the coils. It is what the coils plug on to. To replace it removal all the coils and unplug it.

The ignition module is the flat unit that the coils are attached to and it's usually held onto the engine with from two to four mounting bolts and there are two or three connectors to disconnect. I usually leave the coil packs on it until I have removed it from the engine then I remove the coil packs from the old module and transfer them to the new module. Most of the modules sit on an aluminum plate that is a heat sink [keeps the module cool] If you have a new module you'll be able to easily see how it goes together. You're assumption that the module is bad is most likely correct. Generally if the other two coils are firing properly but the third coil is dead [and a new one has been tried] then it means that the coil driver circuit in the module has failed. Make sure the plug wires are all good as a bad plug wire can overload a coil and cause the new module to fail. Good luck, hope this helps out a bit.
