Hi everybody.
i have a 98 TJ Sport with a 4L
The Jeep wont start, or turn over, or anything unless boosted.
it fires right up when boosted however. I took the battery out and brougt it in to be load tested and they told me it was fine. ANybody know what else could be wrong?

 

Bad Ground Or maybe a bad starter ???????????

 

For sure you need to rule out a bad ground or similar simple stuff before digging deeper.
Check out and clean up all the battery connections and cables.
