2000 Buick Lesabre cranks, but won't start

I had a si liar problem and it turned out to be the starter. Many mechanics missed it because it as intermittent, sometimes would start, sometimes not. We went crazy thinking it was a pass key 3 security issue and tried many tricks to teach the key..blah blah blah. In the end it was the starter..the bushings were worn. Put in a OEM one though, so it lasts.

Did you figure out the issue, because mine is doing the same thing.

Check the ignition control module
