Believe it or not it all comes down to sounds. If you hear a clunk noise chances are its the starter, if you get air like no noise at all its a bad connection either at the battery or at the starter. Beyond that you gotta start looking at expensive things like computer or possibly in rare cases its the fuse (which will make a fast ticking sound). To clean the connectors on the battery go to any battery shop and find the "pin or GM terminal cleaner" it looks like a drill bit with metal brushes on it. with one to go into the gm post it will make the gm posts shine like a nickel then take a set of channel locks and remove the GM lug from the connector and use it on that too it will come out a copper colour or extremely shiny silver then put it back together and use some white lithium grease on it and hook it all up and see how it works if you have to start messing with the starter your better off to take it to a mechanic because there are alot of little things that could go wrong.
