Is the security light going out when you crank the engine?

will have to check...u mean engine light?
Buick Mechanic: Mike V., Auto Service Technician replied 7 months ago

No, there should be some type of security light that flashes on the dash when the key is out of the ignition. If the light is going out when you turn the key on.

If it is, then the issue is likely the ICM, this is mounted under the ignition coils. It's fairly common for the ignition control module to fail and for you to lose spark.

Please let me know if there is anything else I can do to help.
