Jeep won't start, can't get starter to fire up

Hello, this sounds like a starting system issue. Start by testing the 12 volt battery for state of charge and then also the ability to handle a load. If it fails, replace it and recheck starting. As always, check for any corrosion build up on battery cables and ensure connections are secure. If the battery tests good, all cables are good and connected properly and the starter is verified to be good, I'd then check the engine to make sure it manually turns with a breaker bar and socket on then crankshaft. A locked engine, of course, will not crank. Hands on inspection is needed. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
