I know that the 93 3.3 V6 Skylark I have was stalling and hesitating, After replacing alot of other parts it ended up being the Idle air control valve. It's just two bolts and any decent autoparts store stocks them. You could even just clean the old valve and bowl assembly up with some spray carb cleaner. Remember to clean the bowl out before you put the new one in or it will stick too. The carbon really builds up on them and causes them to stick. (bad design)

What would cause Buick Skylark not to start with a new starter?

You need to be more specific about your problem. If it fails to crank, it could be it is not installed properly. Shims may be needed to make sure it engages the fly wheel gears properly.If it cranks, but does not start, then there are many electrical problems that could cause this. This begs the question, did it run OK before replacing the starter?
