I realize this is an old thread but perhaps my experience might be of some help to someone.
My 89 fj62 had the click no start intermittently for a long time. I finally got stuck. I have replaced relay, starter, starter ground wire, ignition switch. It still happened fairly regularly but cycling key a few times usually fired it. This time was no go.
So I had no start in a parking lot. Jumpstart from another vehicle yielded same results. So......I figured it had to be wiring. I ran one leg of my jumper cable from the main + terminal on the starter directly to the + battery post and the old girl fired right up.
I just finished making and installing new +\- 2 gauge battery cables with 2 x 5/16 crimped ends, heat shrink covers. I am confident i finally have it...... knock on wood. In hindsight I should have gone at this smple, basic solution in the first place. Sometimes it is the simple stuff.
Couple of pointers in case reader doesn't know. Buy a hand held hydraulic crimping tool. Cheap. Life is easier if you remove air cleaner box to get to where ground wite is attached and running new cables nice and neat. Note the air box is mounted with 3 14mm(?) bolts: 2 are obvious but one is accessed from the wheel well outside. Look above the tire about 1:00.
The next time you get this issue, try what i did. If it starts you have narrowed things down. Hopefully you won't have to lay down in a slushy parking lot like i did....fortunately i had a tarp in the rig. 34 year old battery cables i guess go bad although i think the issues are really the exposed crimped ends rather than the actual cable itself.
Cheers
