I have a 2003 Jeep Rubicon and the radio doesn't work in the "on" position when the vehicle is running but it works when the key is turned all the back backwards in the auxiliary position? Please Help
The actual key cylinder itself or the ignition starter switch? Thanks Allan!The actual key cylinder itself or the ignition starter switch? Thanks Allan!

I found so many manuals that aren't here.. Also complete, this one is not, much better language, co mplete manual of 800+ pages, and they also have live assistance feature
I had a similar issue where the alarm went off, pulled the battery to silence, and upon re-connecting it the Jeep wouldn't start. It's a protection mechanism built into the security system to prevent tampering/bypassing the system. The computer goes into lockdown and won't start...
To clear it you have to reconnect the battery and leave it sit. It's supposed to be a 60min cycle, but it seemed like it took longer for me. I plugged it in before leaving for work (in my wife's vehicle) and she tried starting it several hours later when she needed to run an errand and it started right up.
Honestly, it sounds like a bad ignition coil. When they get corroded inside they will draw power on a scale much higher than anything else on the vehicle. It is a coil and it's job is to take a little power and make a lot of it. If it's only when the key is in the "run" position, that is likely the case. The only real difference between the two positions is that in the run position there is power being delivered to the ignition system. Good luck.
well i would think the crankshaft position sensor it bad/in wrong position/or the bell housing holds the crank sensor to far away from flywheel.if my memory is correct anything other than the jeep bellhousing wont work with the jeep fuel ign. system
Bad starter or starter Solenoid. Grounded wire between the solenoid and battery or actually a bad battery. I've had batteries that were bad where everything worked until you went to start teh engine then it wouldn't turn over. There are 2 parts to the battery, 1 is voltage which runs the radio, windows, lights and such the other is Amperage which is needed to get the started to work. You can have good voltage but no amperage due to a dead cell. Disconnect the Negative battery terminal, connect jumper cables to a goo running vehicle, connect the positive cable to teh positive terminal and the negative clamp to the negative cable, this take your battery out of the loop, then try and start the vehicle. If the vehicle starts it's your battery if it doesn't then it is most likely your starter or Solenoid.
I had the same problem with my 2007 Sahara Unlimited. I'll make a long story as short as possible. For a number of years my son ran a Chrysler / Jeep dealership and I contacted him (I bought my Jeep from him before he got out of the business) and he told me this is a sporadic problem with the Wrangler line. To the point of calling him I had tried everything and nothing worked...insert key, turn, nothing...all electrical worked, lights, power windows, radio, etc, etc. He told me to disconnect the negative power connection on the battery for a second or two then re-attach. Insert key, engine starts, everything works as advertised.
Essentially, my son told me this "re-boots" the system. For whatever, and to his knowledge, never explained by Jeep, this fix works but no idea as to why it happens in the first place.
Hope this is of some help...though I suggest that there may be more "fixes" to this problem.
The ignition switch has many wires to it, 1 for starting, 1 for acc(key turned back), 1 for on or running.
Check all wires to the switch to make sure nothing came loose.
