Ok here is the deal my 88 Buick park ave decided to die today. It has no spark. I replaced the coil pack,new crank sensor, checked all the grounds, ceck for injector pulse. Everything checks out fine but still no spark.

maybe your not getting the signals to the pack

replace ignition module and al the packs from another Buick now it will start but runs like it is out of time

Well i would check the coils on this ''new'' set you put on
