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?



    Reactions: ALAN TUCKER and Chris
    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???

It sounds like the ignition actuator tip has broken (common, known problem). Here is a link on checking it & testing the rest of the starting circuit too.

So Rubi, just got the T-10 security but from amazon and removed the ignition switch- pin looks to be in perfect shape, metal is good, no stress fractures, breaks etc.
could it be as simple as the relay even though the old starter relay is in the fuel pump position now and still works??? So confused. Always thought relays were like fuses- either they work or they don’t.

Not likely a relay problem, they rarely fail & swapping it removed it as the cause since as you noted, the horn worked with it in that socket.


With the ignition switch separated from the actuator did you turn the switch with a screwdriver to see if it would start as recommended in the link I posted?

That would test the rest of the circuit. If it still did not start that at least begins to isolate the problem.

If it will not start turning the switch the next step would be to pull the starter relay, make sure you have 12v power to terminal 30 in the socket, make sure you are in neutral, and with a short jumper wire jump from terminal 30 to terminal 87. That should engage the starter. If so you will know the circuit from relay to starter is good & your problem is between the ignition switch & relay.

Post results & I can advise further as needed.

So let me bounce this off of you- I have an ADE-II theft deterrent device which was working fine, before the starting issue began I extended length of wire to the reed switch so I could locate it in a better position. So- that’s when the troubles began which I mentioned before. I removed the system and reattached the main wire that I spliced into and wasn’t getting ignition. After reinstalling everything after running your tests and Jeep starting fine, it did the same thing- battery lights radio but zero start or clicks. Frustrated I turned the key all the way back using that key release button then turned to on position and cranked right up!?!?!? Starting fine every single time now.

I can’t explain how turning is fully back (acc position) would “right” everything but will take the win.

So, at least for now everything is good, right?

I did see you had some type of security device & that would have been the next thing to check. I know nothing about that one but know anytime you add mods to the system you have to consider they might be causing the problem. Most of the time it seems that these types of things are installed by previous owners & the new guy has no idea of how it was installed & how to check them. It sounds like you installed yours so that is good & you know how to disable if needed.

Yep- all is well now, and yes i installed the security device exactly per ORO’s instructions. I thought that could have been the problem initially as well so I disabled it and put the Jeep back to stock , but initially that did not cure the problem. I am at a loss as to what got her running normally again and frankly am a bit nervous that it could arise again but fingers crossed and thanks for all of your help!
Next project is to rewire that lead for the daylighters so they will be only available with jeep running.

Mine did the exact same thing the other day. Started it to go to work, forgot something inside, shut jeep off, went inside and when I came out to start the jeep.... nothing. All the lights and everything else worked, but when turn the key nothing from the starter. Decided to tap on it with a hammer, jeep started but wouldn't restart. Took all the connections off and cleaned them, cleaned grounds, started once.
Got a cheap starter from the JY, started right up and hasn't been an issue since then.
