Oldsmobile Aurora won't start, possible coil pack issue after battery and plug changes on Oldsmobile Aurora

Some Oldsmobile Aurora owners report experiencing starting issues after changing the battery and spark plugs, potentially due to a faulty coil pack. These owners note that a malfunctioning coil pack can lead to poor engine performance, including symptoms like rough idling and misfires. Additionally, they may find that testing the coil pack with a multimeter for resistance levels or checking for specific diagnostic trouble codes (DTCs) can help identify the problem.
