05 TJ was not starting
Sunday afternoon I went out to start the jeep after fiddling with wiring on my daylighters. It would get power when the key was in the on position to the dashboard, lights, radio etc. but would not crank- starter made no noise whatsoever. I checked the voltage at the battery (12.4V) and at the starter (same) so I assumed it was a dead starter but suspicious because it has never given me issues since i've had it- no warning clicks in the past, difficulties etc. Read up on some posts on things to try so:
- Tried jumpstarting- no go
- Checked all clear fuses - all good
- Swapped starter relay with horn relay - still would not start and horn continued to function so assumed both relays OK
- smacked on starter a few times - nothing
- unwrapped entire ORO ADE-II system (was working fine but was willing to try everything) and set back to stock- nothing
- Got some great advice from Ironhead Jed - thank you sir! and checked out even more links from him:
- jumped wire from pos posts to middle contact of starter relay (per this thread- Gatesjeff33

Don't forget to swap fuses and to swap relays around inside the fuse box.
If you are stranded, you can try this trick...
1. Put the parking break on and take the vehicle out of gear if it's a manual!! Very important that you aren't in gear. Turn the key to the ON position.
2. Remove the starter relay(It's in the black plastic box under the hood)
3. Short a wire from the positive battery or positive fuse box terminal to the center contact of where the relay goes. (There are 5 contacts on the relay. You want the one that is in the middle, i.e. dead center.)
4. If the car starts, your starter/solenoid/battery are fine. You've got some issue with the clutch safety switch or ignition.
Now, I couldn't start my Jeep with the key today, so I used the jumper method and it worked great. I used a screw driver and a bare metal wrench to short the positive to the center relay contact point. Some real MacGiver kind of stuff. I was highly suspect of my clutch safety switch because it had been very picky about where the clutch was positioned, so I disconnected it and cut the wire right next to the switch. I took the electrical connector out and shorted the wires and reinstalled it. The Jeep still doesn't start....
I noticed some corrosion on the connector, I cleaned that off and plugged it back in. Jeep still doesn't start.
What else could be wrong? I swapped relays and fuses also. Is there corrosion on the other mating plug connection? Or is there something else that broke?

and voila- she was trying to start!
- Key goes into ignition fine, just like before with no more resistance- functions just the same so hoping ignition switch is OK
- disabled clutch safety switch per owners manual by placing 10A fuse in PDC space
- Confused as heck, tried swapping relays again since battery and starter are obv good and was grasping at straws. Put the fuel pump relay in the starter slot (all three mentioned are the same of course) and first attempt nothing, second it starts right up.
- WTH??? Thoughts guys? Could that relay have been causing this but still work for fuel pump/horn???
