Been fighting this for several years(not kidding, people are making fun of me at work)....the common no start issue many of us have. Symptom is no hint when it will happen, cold or hot, turn key hear nothing except what sounds like a relay somewhere, (might be something else). Sentry key fob will activate security system. Horn or wipers don't get possessed like I have read some others have experienced. Maybe my issue is unique. I have not been to the dealer for any of this, don't have much faith given history of much more simple fails.
Subject JK, 2008 JKU Rubi, 70K miles, 6spd, lots of electrical accessories including LED fogs, tail-lights, 40" OUTLAW LED BAR, Warn Winch, 1000W Power Inverter.
Here is what I have done:
Replaced Battery for Interstate AGM; healthy, holds charge well, and alt putting out to spec.
Replaced Battery Terminals (just the terminals) for the quadratec multi connects to accommodate all the accessories
Replaced Starter Motor Twice.
Shifted manual shift and transfer case in and out and slammed door so as to jar any loose connections...
Unplugged fuse box from harness, cleaned plugs and terminals.
Added 50" 8AWG ground wire from negative post to Alt bolt.
Swapped out 8AWG for 4AWG above
Done some hammering on starter at time but mostly a slap on the fusebox, which usually works 9/10 times. Been doing this for the last year and a half. Its easy simple and doesn't get me dirty.
Pulled and Reset the I/O fuse or whatever its called
Next planned mod is to rig a switch to the I/O fuse to reset from drivers seat.....
P.S. I am so very sick of this. Any other options that most of us haven't tried. Is it time to try that fusebox relay re-build on ebay
