2006 buick lacorsse crank over nospark

Customer: replied 8 months ago.
The car will crank over but has no sparks to the spark plugs. I have replaced the crank sensor,and spark plugs and checked the spark relay and it is good. checked the pcm fuse and it is good as well. what is something else that can cause this problem?

Hi, My name is ***** ***** for the delay.I will do my best to assist you.
Expert:  tim's auto repair replied 8 months ago.
there is nothing else for the spark,,the ignition module is built into the pcm on this unit..
Expert:  tim's auto repair replied 8 months ago.
if you are sure the crank sensor is good,then i would think your problem is the pcm[computer] itselfthanks
