I am trying to find out why my 2009 chevy hhr won't start?

What is your question?

Started chevy up, at first it hesitates to start . Before it stopped cranking I took it to auto zone but the reading said alternator, starter, and battery were good but they could not check solenoid.Returned home and tried cranking it, now all we get is grinding and clicking noice, is solenoid bad? It has 2001k.miles on it

What makes this problem better or worse?
