My '84 Jeep CJ 7, 4.2L, inline 6, 5 speed manual tranny, with 140,000 miles won't start. I took it for a spin last month, and then when to start it up again on the way home, and nothing. It sat in my garage since. I tried to start her up the other day, and got nothing. I tried to jump it, and just got clicks, but only when it was hooked up to the battery charger. I replaced the starter and terminal clamps, and still the same. My next bet is the solenoid? Any help would be greatly appreciated on what I should do next.
