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.
