I can start it with the key but only if I put the distributor wire on a prong on the relay that is "always hot." But if I have it like it's always been, on a prong that is only hot on crank and run--then it won't crank with the key.

Does everything else in the Jeep have power? Guages, Radio etc?

It also occured to me that a 94 has a engine compartment fuse box. I don't remember if you said if it has the original fuse box in the engine compartment by the battery. If so have you checked all the fuses in that box to make sure nothing is blown?

Ok so that limits the problem down to the Distributor wire or ignition switch, on my Wrangler its Yellow and plugs into the blue part of the switch. If your looking at the switch under the dash its the top left wire.

We can test this:
First thing you need to do is get out the multi tester, put the key in the run position, then check if your Yellow distribotor wire has 12 volts. I going to say it probably wont have 12v's.

The second test will be to test for 12vs with they key in the run position at the switch atop the steering column.

Where I put that white circle you should see a Yellow wire going into. [Mine melted which is why its missing.]
You want to test it there for 12v's. If you have 12v's there then your wire from the switch to the distributer is bad.

The easiest thing to do will be to splice into that yellow wire and run a new wire back out through the firewall (The wall seperating the inside of the vehicle from the engine compartment) to the distributor. You will also need to run a wire from there to the Brown wire on the alternator, and then to the Choke.

If you do not have 12v's at the Yellow Wire then your switch is bad and needs replaced.

We would normaly test the income power wire to the switch next, however since you can turn over the starter we know you have power to the switch.

Yes we have power to the radio and guages. We replaced the switch b/c we had it all open. We had 12v at the switch yellow wire when in run and in start. Does that mean my wire is bad? When you say to secondly check the yellow distributor wire, are you meaning check it at the coil for 12v and have the key in run while doing so?

Yes at the coil, my 350 has a all in one coil and distributor [HEI]. After everything that wire seems the last possiblity. To be 100% before you attempt replacing it make sure it does not have 12v's at the coil. You can check the brown wire at the alternator as well for 12v's while the key is in the run position.

If you dont have 12v at those wires then we have found the culprit.

Did you get your jeep running....I think I am having the same problem. I have a 90 yj with a v8 conversion that just stopped. The engine turns but just will not start. The wiring on the conversion was done poorly. So I got on ebay and bought replacement harnesses. I rewired everything... It started...left it alone for a couple of days and went back out and now it won't start...just curious if you figured out our problem.

If I remember correctly they had a broken iginition wire from the column to under the hood. They ran a new wire and rewired all the stuff connected to that under the hood.

----------------------------------------------------
Couple things you need to determine:
1. Are you getting fuel inside the engine.
2. Are you getting spark from the distributor.

If your starter is turning the engine then you either lack spark or fuel.

As a side note you might want to do some troubleshooting and make a fresh post, as there is a ton of helpful people that can help you run down the problem.

The alternator recently failed in my '95. I put a new alternator in, and it wouldn't charge the battery. I scratched my head for a while before I found the pair of big 50A fuses in the engine bay fuse box. Sure enough they were both blown.

I think the old alternator failed in such a way that it essentially shorted the battery to ground blowing those big fuses.

A new alternator and fuses did the trick for me.

Yes we had bad wires and had to rewire from the ignition switch at the column and thanks to Master4th for his help, we were able to do it! He's a great source of information and never gave up on us even though we are "mechanically challenged." He's an asset to everyone here!
