2004 Aveo not starting consistently (after battery replacement)

I have a 2004 Aveo and recently it has been turning over but not starting. It all started after replacing the battery. We changed the ignition switch and the fuel pump and checked all fuses. It will start and run for a day or 2 and then not. Sometimes I have to sit and wait about 10 minutes and try again and then it will start. What else could possibly be causing this issue?

Sounds like it could be a ground issue potentially, i am not sure which grounds to check specifically. I once had that issue happen on an old van that i had and it was a ground wire coming from the cylinder head and going to the firewall.
