2014 Chevy Traverse LTZ

This has been parked for almost 2 years - was cleaned and everything first. It's got a new battery in it , im not exactly sure what it needs . It starts and stays running but once you shut it off - you have to jump it again for it to start. Possibly an easy fix? I don't have time or the money to do anything with it so I'm looking to sell! Mesage if you have any questions
