I just went out to mine with a jumper hooked to a straightened paperclip. (barefoot and naked, in the snow). (the photos didn't come out). Seemed easier than finding the diagrams. The forward end of the start relay has THREE blades. Top runs the fuel pump, (which Renix does while cranking). The bottom one energizes the starter solenoid and makes it crank. (green wire) Annoyingly, juicing the middle one made it crank also, but pretty sure the lower Green goes right to the solenoid. Working on better photos...

Oh and YES! snow down to sea level here in N Ca, and over 6 inches here at 1,500 feet!

Fellas, sorry for the long delay in response to this thread. As I mentioned last week, my daughter was sick and she was kind enough to share it with me. I was feeling like hell and I actually decided to stay home this morning, but as the day wore on I started feeling better and got bored. So out to the Jeep I went. I started by testing the voltage to my solenoid (0v), then starter relay wire-by-wire, as I was just *certain* that I had burned out a fusible link somewhere, well, apparently I hadn't.

Anyway, to cut a long-story short, I remembered from this video on youtube,
, and it was from this video that I realized that my DAMN NEUTRAL SAFETY SWITCH was causing all my problems. Yes, I'll admit it, I was stupid and ruled out the NSS earlier in this thread. Well, I was wrong.

But for future posterity, here is how I figured out that it was the NSS:


Ok, so seeing the 5v at ignition terminal is what tells us that we are having a problem - we shouldn't be seeing any voltage there, but because we are, we know the NSS is the problem.

*edit* I should note - you should always see ~12v at the battery terminal...

So I won't go into the removal, cleaning, and rebuilding of the NSS because it's been done a lot elsewhere, and better than I could anyway, but suffice it to say, after I cleaned it and reinstalled it, the damn thing started right up upon the turn of the key. I do need to go back under there and readjust it some - my shifter is very tight, but that should be easy enough.

Moral of the story is; even if you think it's not your NSS, check it anyway.

actually, a Better Moral of the story is: Don't rule something out unless you've actually checked it...

That was some good detective work. Congrats!! Glad you got it running and working like it should. You'll really appreciate it now that she's reliable again. I give you major kudos for persevering and thanks for sharing the image. I'm going to print it out for future reference.

Thanks fellas, I appreciate it, but you may want to hold your applause...

I was planning on driving Ole Jeepie to work this morning and she cranked up perfectly - very satisfyingly, I might add. The shifter action was still hard, as I had expected, but I didn't *think* that it would have any affect on how the it drove. Well, I puttered down my alley like normal and as turned out onto the main street and began my trip to work. As I hit about 25-35 mph I started getting a shuddering and like, a clicking noise coming from the transmission. Best way I can describe the sound like like when you hear a relay opening and closing..."click click click click" while shuddering and not wanting to accelerate. Well I was running late already so I turned around and limped her home.

So - does this issue have to do with my poorly adjusted NSS or do I now have another problem??

Thanks Gents,

-Matt

BTW guys, I recently had a strange no-start situation (out of the blue). Turn key, not even a click. I know the batt is good, and other things had been looked at in the past.

What it took was a few taps on the starter with a long pry bar. Starter was stuck. It might be near the end of it's life. The point is, it's another trick that works on a lot of starters when they don't 'go'. Especially GMs. The best approach is to get under the vehicle and tap with a hammer handle (not the head). But I was lazy at that moment!

Flintstone/Cruiser - Thank you both for tag-teaming to get me the response. I wonder what is going on with DF's account? I looked around and it doesn't appear there is any way I (or anyone as far as I can tell) would be able to block him from this thread.

That said, I really appreciate the feedback and assistance!

Ok everyone, final update! I went out today and re-adjusted my NSS and we're back in business. The bucking in the transmission was definitely caused by the overly tight NSS nut. After loosening and readjusting then we were good to go!

A big THANK YOU to all of you for your assistance with my issue and helping me get back on the street!
