Food for thought 97 no start with power misdiagnoses

This is a little long winded so bear with me. Took my Wrangler out over the holiday, and did a lot of back wood dirt road driving. By the end of it all my dash was making so much noise it was driving me crazy. So I ripped it out, and cleaned everything, and it was a great learning process along the way. I also found what I think is pretty smooth way to get the passenger side air bag cover off that I have seen people have had problems with, also learned a valuable lesson when putting it back on. Need less to say got the dash all the way back together, turned the key, and had good power to everything but it would not crank.

So I started looking at forums and threads to see what is common, there a bunch of videos and threads about the pin actuator, and ignition switch. I did exactly what the threads stated, and still had the same problem. Needless to say I replaced the pin actuator, ignition switch, and starter relay. I swapped out the ADS relay to the horn relay, and I pulled the starter and battery, and had them tested. All of that left me with the same problem of good power everywhere, and no cranking from the starter. I found the starting circuit here, and did some prelim diag believing I found the problem but too late in the day to keep going. Needless to say I spent Tuesday starting my Jeep with a screwdriver at the starter.

I only bring this up as I found a lot of videos of people going after the pin actuator, and ignition switch, and still getting the no crank no start. In these videos I see people just bypassing the system with a push button starter, and I Think this may boil down to a common wiring issue. I found after doing some electrical digging, the power wire from the ignition switch to the clutch bypass had no continuity. I confirmed it by testing the sockets before I stripped back the wires, I then ran a jumper bypassing the loom, and bang Jeep fired right up.

Just wanted to get that out there if you run into this problem on your rig.

wow this is handy for me, i current use the push button method, my ignition never came back online after numerous investigations. I even spent about 6 months using the screwdriver method, which believe or not, actually was kinda cool. A lot of people seem to think that was cool like in front of a bar or a club, but not so great on my clothes or if it was raining or a filthy gutter. I had to strategic park where is was clean-ish for a while.
