No, the power for the coil does not come from the icm, it comes from a tap that feeds the icm

These diagrams are from a 1982 CJ7, 258, un nuttered.

They "might" match yours.

Following the coil instructions the 2 horseshoe posts will sit at .0l or .002 ohms set to 2k ohms on meter. Saw it jump to 1.4 ohms once when moving the tips of the meter around. Then positive to post and negative to inside of the tower had the same reading of .0l never changed from that. Did it all set to 2k ohms. Digital meter man.

Also I would like to thank you for your help so far.

Forgot to add that the distributor plug reads .602 ohms.

When you tested inside tower to a contact, it should read 7k to 9k..., if your meter was set for 2k ohms, it wouldnt be accurate. Set multimeter to to 10k ohms, verify it.

Your coil may be dead.

Only have 2k or 20k ohms. Set to 20k and some wiggling around it read 8.55 ohms.

I dont have enough knowledge, but i wonder if set at 20k it reads 8,500 ohms?
If thats true, then your coil may be good.

I just checked my old coil, ohm meeter set at at 200k, center column to either post reads 6.9. So your coil may be good as well.

Next would be to look at your icm. Visually is it ok? Anything leaking out of it?
Did you leave the key on for a time without it running?
Some of the photos show how how to test the icm, if its the same as in photos.

Tried it at 200k and got 8.5.

No leaks out of the ICM. It is lightly covered in dirt.

It drove fine when I went and got the distributor. When I went to install it I removed the key from the ignition. Then no start after installing parts.

Looking at the photos the plugs on the ICM look identical to mine. However I don't know the orientation I'm suppose to hold them at to find the correct pin I need to check.

If Coil and ICM check out where do you think that leaves us?

Then that doesnt matter. The nutter just takes the ecm out of the loop, the wires from dizzy go syraight to icm correct?

When you say big cap, are you talking the team rush with ford 300 ci, cap, rotor, adapter?

Break it down into steps.
You need 12 volts from key to coil, which you said you have?
The coil seems to check ohms?
But you dont have power from the coil to the dizzy? Correct?
How are the connections on the wires to the coil? Secure? No broken wires?
If both green and red to coil are good, the coil has input.

But did you ever check the coil wire to dizzy by grounding it to the block?
If it produces a spark, then it is a dizzy problem.
If it does not, the dizzy is good, coil, coil wires, connection to icm, icm itself.

Im thinking but its also laye.
Im surprised no one who knows YJ's has stepped in.
Yours is 7 years newer than mine lol.

Doing the sensor and control check picture. Step 1. Can't get spark. Go to step 5. Assuming I have it facing right. The bottom left plug reads 1.1 ohms on 2k setting.

Yes ford 300cid i6 adapter cap rotor.

We have 12volts to the end of the horse shoe. Coil seemed to check out. I tried grounding out the wire but saw no spark. All wires look good. No corrosion just covered in grime.
I cleaned it up.

Dizzy is brand new.

Yeah it is getting pretty late.
