So I haven't started my Jeep in awhile. I went to start it and nothing. Figured the battery was dead so I got a jump box and the starter just clicked over and over. At this point I figured the battery was drained and maybe the starter was bad so I tried to coast start it and nothing happened. I was going down a hill in second gear and the engine just turned over like normal but nothing happened. I'm going to take the battery and starter in the morning to be tested but it still seems like something else is wrong.

 

I wouldn't pull the starter yet. Suggest removing and cleaning the battery terminal connections, and measuring the voltage with jumpbox connected while some tries to start it with the key. If voltage goes below 9 to10, the jumpbox probably can't supply enough amps to start. Coast starting only works if the battery still has enough power to run the fuel and ignition -- If the headlights don't work it's not going to start. Most likely problem is the battery and/or corroded battery terminals.

 

Ok thanks.
