coil pack and ignition module are good still no spark -
Answer 1
Check for injector pulse, if no injector pulse then suspect a bad crank sensor, which will also cause a 'no spark' situation. I worked in GM dealership and this was something that I often found to be a problem with these types of cars of this era. -
