Ignition Module Question
 

I ran into a problem with the car getting no spark,replaced the coil and it ran great for aprox. 6 months and I now have the same problem. Could the failure of the Ignition Module cause this problem?

what year and model do you have?

Ignition Module Problem?
 

This is a 1991 420 SEL

Yes replace the EZL since you already changed the coil you will be ok with a used one, these parts are not cheap they fail from just use, heat causes them to fail. when you remove it look at the heat sync compound on the bottom if it is hard it's not doing its job of transferring heat. which will cause the failure other then this just age.

Kg, Radio Shack sells the white heat-conducting paste if you need to add/replace the paste on a used ignition control module.

Yes it could. But, so could a faulty Crankshaft Position Sensor.
