Won't start or turn over battery tested good replaced starter still nothing

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If your 2016 Jeep Cherokee won't start or turn over, and you've already tested the battery and replaced the starter, the next suspects could be the ignition switch, a faulty relay, or an issue with the wiring harness. Sometimes, a poor connection at the battery terminals can also cause this problem. It might be a good idea to have a professional check the fob and starter relay to rule out any electrical issues.
