92 xj 4.0 manual tranny. battery only about 4 months old. holding 12.6 volts right now. the jeep will not crank the engine over. the fuel pump cycles strong and the head lights are strong. when I go to turn the key to start the engine,it just goes to the start position and does nothing. no clicking,nothing. I did notice when I would drive it for the last couple days,the starter seemed to be dragging and turning over slower than normal. I can't crawl under it today,but i did clean the battery cables even though they weren't dirty,and tried wiggling the wires for the starter from the top of the engine,none appeared loose. would this be the starter gone,or is there something else that could be the problem? just looking for ideas to check out so when I can work on it next,I don't spend a lot of time on deadend stuff that is not related to the problwm. thanks for any ideas,Ben
