How do we troubleshoot an intermittent starting issue? on 2005 Chevrolet Trailblazer

We have a 2005 Chevy Trailblazer that has recently been having an intermittent starting issue. We have replaced the battery, ignition switch, starter relay and had the starter tested - it's good. So we are not sure what to do. The car may start for several days and then you go to start it and all the lights come on and the accessories work, but it won't start. After lots of tries it may start and it may not. We would appreciate any help and advice. Thank you!!!

COULD BE INT STARTER STICKING INTERNALLY. NEXT TIME STARTER DOES THAT TAP WITH A SMALL HAMMER AND SEE IF THAT HELPS IF SO REPL STARTTER. MAKE SURE SOMEONE IS INSIDE AND HAS KEY IN START POSITION AND E BRAKE ON

YouTube the video on starter problems. It has been helpful, either the starter relay or a faulty, opened circuit.
