84 CJ7 turns over but wont stay running

So i'm sort of a newbie... this is my 3rd jeep but the first one i've had to do a lot of work on. When I turn the key all the way, i get nothing, but as I let the key back it turns over my engine. when the engine finally catches, and i let off the key it shuts down. Its got a brand new battery and starter solenoid (put them in yesterday). I'm wondering if it is having issues because of the cold (its 28 out right now). I've only owned the jeep since august and it has been one headache after another. Any help would be great. I ordered a new ignition cylinder but i have NO CLUE how to replace it... so if thats the problem, help on that too would be great!!!

Thanks!

T

Most likely not the problem. The key cylinder, as it turns, moves a rod (hidden on top of steering column) which actuates the ignition switch (also on top of the steering column. It can be seen under the dash in front of the brake pedal).
It seems as if your rod is moving. The switch can be adjusted by loosening it's two mounting screws and sliding it forward or aft. I would try moving it forward a little.

I was having a similar problem. The Jeep would start, and as soon as I let the key back, it would die.

I replaced the ignition switch and it didn't fix it.

Eventually, I traced it back to this little black relay by the firewall behind the motor. I still don't know what it was as the previous owner did a lot of rewiring.

I took out the relay, hit it with an air compressor, plugged it back in, and it started up and ran fine.

Yes could be the adjustent on the ignition switch. If it moves to far to start cranking, it might also end up in the wrong place to keep it running.

Try to adjust it or figure out what is going wrong.

It may also be the rack and pinion on the key lock acting up.
