theksmith 2,442 Posted September 17, 2021 (edited) Brady replaced the ignition switch (part #4685719AI) to hopefully resolve an intermittent no-start condition. he got the Doorman version on Amazon for $15. apparently these are a common failure on older JK's. sometimes he would get a "click" like a weak battery or bad starter, but then other times he got no response at all from turning the key. simply pulling the key out, putting it back in and trying to start it again would sometimes let it start right up. FYI, you only need to remove the steering column shroud to get to this (steering wheel stays on). also, this is just the electronics, the actual lock mechanism stays in place so you don't have to re-key either. just need a T-10 Torx bit on a 1/4" ratchet to get to the one screw holding the module on.

Trail Toy 920 Posted September 17, 2021 I found that if I push the transfer case shifter and transmission shifter forward my rig will start. Share this post Link to post Share on other sites
theksmith 2,442 Posted September 17, 2021 Just now, Trail Toy said: I found that if I push the transfer case shifter and transmission shifter forward my rig will start. so you're saying you have to "push start" it? 5 Share this post Link to post Share on other sites

Trail Toy 920 Posted September 22, 2021 (edited) Sometimes I have to wiggle the transmission shifter to get it out of park as well, this tends to be a problem when my rig has been sitting for a while. After a couple times of this it stops acting up and things go back to normal, until it sits for a while again. I'm thinking safety neutral switch/trs but who knows... Next time I have this no start issue I'm gonna see about grounding that wire in connector 4 and see if that helps.

Trail Toy 920 Posted September 22, 2021 (edited) I just discovered there's an override for the tranny shifter lever if it won't come out of park. Just tested this in my rig and sure as it worked! From the passenger side I put the key in, turned to "on", tried to shift without foot on brake and no go, pressed the override down and it shifted with no issues. You still have to push the thumb button on the shifter handle though. Also discovered if you push the override down and back just a hint it will stay in the override position.

Trail Toy 920 Posted September 24, 2021 (edited) I found this Mopar web page that shows a breakdown of connectors, pins, wire color, etc., very useful! Edited September 24, 2021 by Trail Toy 1 Share this post Link to post Share on other sites
theksmith 2,442 Posted October 18, 2021 (edited) the 2.5" Teraflex coil spacers that Fiona came with have been crumbling apart in the rear for some time... we just kept sweeping up the chunks from the driveway for a while Brady had Columbus Day off from school and work, so we finally had a chance to replace the spacers and factory coils with 2.5" lift Teraflex Coils that @AZRNintheJeep242 had given us (thanks Darryl!). talk about dry-rotted, sheesh... one of the front spacers was cracked, and the other was OK - no idea why those were in so much better shape than the rear. anyway, Fiona is sitting pretty on 4 new-to-her coils now, and everything else seems to be holding together... so we're ready to go flex-test to see if any additional bump-stopping or fender trimming is necessary. hopefully we'll have time next weekend to do that and then Brady can finally start wheeling her!

Trail Toy 920 Posted October 18, 2021 Reminds me of when I replaced my shocks, the rear lower rubber bushings doing the same and one of the metal tubes inside the bushing was broken into several pieces. Share this post Link to post Share on other sites
jgaz 379 Posted October 19, 2021 (edited) Nice to see Brady twisting wrenches on his rig. Too many kids these days don’t have any mechanical skills or at least an appreciation for those skills. Those rubber chunks laying in the floor remind me of Michigan rust falling off one of my many work beaters. Edited October 19, 2021 by jgaz 2 1 1 Share this post Link to post Share on other sites
