jeep turning over but not starting (no fire)

We have changed the ign coil and ign module but the jeep wont fire. No power from the coil to distribitor.

There is also the pickup coil in the distributor. You can test it with a multimeter. It should read 400-800 ohms between the orange and purple wires with 600 being best. Neither wire should show continuity to ground.

Next check is to be sure you have power to the coil positive when the key is in run and in start.

more information

Thanks i'm going out tomorrow and check that out. Power is getting to the coil but not the distrib. 1 hot wire getting to the distrb, no fire coming out of the coil going to the pump wire........does this make sense? This jeep sat in my garage for 7 months I just put a new battery in on Saturday and after about 5 long cranks it started. Drove out to my brother in laws Sunday to look at what was draining my battery (old issue) turns out it was a grounded wire on the horn of the new steering wheel I put on. Because the radio was loosing the presets after the jeep was cut off, we moved the radio or (asses) wire.... it was only put in pulling 6 volts instead of 12. These were the only things we did.....when I went to leave it wouldnt fire. Just wanted to explain what led up to my issue.

I don't get the radio wiring. 6 volts?

I would undo the radio totally, maybe it is now shorting out the ignition depending on what you hooked it to.

Thanks!

We moved the wired and the jeep started! Weird thing is we put it back in the same spot and the jeep continues to start fine! Thanks for the help!
