It is possible you have a bad ignition switch.
That was change along with alternator and crank sensor
I have evap codes and did have crank sensor code but changed that

Check your battery connections. Both ends both cables. Check anywhere there is a ground wire.
OK will do after my baby is born praying it makes it that far my husband is an electrician not a mechanic that's what I am but this has me so stumped

OK! Congrats on the baby! A bad switch or a bad ground somewhere or dirty or bad battery connections are the most common causes of this problem. Hope you figure it out. Good luck!
Ignition switch was changed by dealer battery is clean and still good so assuming bad ground somewhere
Your key my be worn out I have a 2003 trailblazer an have changed everything
This is happening with my 2006 Trailblazer. All the symptoms listed above. My mechanic thinks it may be my neutral safety switch. If it is I will post that information to help others. I notice that people will ask questions about their vehicles but rarely re post after the issue has been identified and repaired.
