If you turn the key to ON position and its not cranking at all,then its battery fault.If its cranking but not starting at all.That means the starter is also getting power.So if its cranks but not start then there are few possibilities to be checked.But if its not craning and no noise then battery and starter are to be checked.In other case :----\015\012\015\012

A jeep that cranks over but doesn't start, in many cases will be\015\012due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or\015\012crank sensor. Also these problems are related to faulty spark plug. Check the\015\012spark at spark plugs when you start the jeep. Do you notice any spark. Actually\015\012you should see. If in case there is no spark then it's a spark plug problem.\015\012Also the coil pack gives power to spark plug. So check the voltage at coil\015\012pack. It will show 12 volt. If there is no voltage noticed at coil pack then\015\012its faulty coil pack that has to be replaced. If all the possible options\015\012checked out ok then check the jeep starter. The starter gets power from battery\015\012to start the jeep. If the starter is faulty then it will not let the jeep to\015\012start. Also check and confirm that there is fuel in the jeep. If its very low\015\012fuel then in some cases this causes the problem. Also check and confirm that\015\012fuel pump is functioning properly and the fuel filter is not clogged. One of\015\012the easiest ways to check for a fuel pump related problem is to spray a little\015\012starting fluid into the air intake while trying to start the jeep. If the jeep starts momentarily, then there's a good chance the fuel pump is not working or\015\012the jeep is out of gas. You can also listen for the fuel pump's humming sound\015\012when the key is first turned on. Also if a inoperative fuel pump is suspected,\015\012a good technician will always check to verify there is power and ground being\015\012supplied to the pump, to eliminate the possibility of a bad relay or electrical\015\012issue. Fuel pressure can be checked with a pressure gauge and if there is\015\012pressure, pulse can be checked at the fuel injectors in several ways including\015\012the most common, with the use of noid lights. If the injectors don't have pulse\015\012the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks.\015\012Helpmech.
