If you are not getting spark, check the coils to make sure they are sending spark. While cranking the engine, lift the plug wire off the coils and see if spark is jumping. If none of the coils have spark, this is a case of a faulty Ignition Control Module (ICM). It's the flat, metal item that the 3 coils sit atop (for an image location view, click here: https://www.dropbox.com/s/dvltnj7nycd9di6/buick-icm.jpg?dl=0). Inspect the electrical connector and wire harness for any loose, broken or damaged wires. If the visual inspection checks ok, replacing the ICM will solve the problem.
