Nutter Bypass Jeep Won't Start 88 Yj

OK, so heres what I did. First at the firewall I cut the orange, purple and light green with black stripe. I connected orange to green and ran a jumper from purple to purple down at the ICM. I was told that I should not have spliced at the firewall, instead down at the ICM. So I reconnected everything at the firewall. Then down at the ICM I spliced into that purple wire and ran a jumper to the purple at the distributer. Then at the green with black stripe spliced into that one and ran a jumper into the orange at the distributer. I've been splicing into the green with black stripe because after the ICM connector the orange comes out green with black stripe and because at the firewall I do not have two orange wires going into the firewall. In any case all this splicing and cutting the jeep has not started at all!!! I am stumped any friggin help, please.

Not sure... Your description has me confused.

Can you post pics of your splices?

I'll search for the nutter post with pics for comparison.

ok photos posted in my gallery. They show the splice into purple before the ICM connector, splice into green/black after the connector and the jumpers spliced into purple and orange at the distributor. Thanks.

Guy the first thing get rid of those splices. Get some butt connectors at least those will cause you more problems the solving anything.
here is a link with picture of the bypass.

Dodger, the one issue I have with that example of the bypass is that I don't have two solid orange wires passing through the firewall. I have that pair of orange and purple that are twisted together and run through the firewall, so where does that leave me? Aside from that one orange wire, I do have jumpers running from the ICM to the distributor...

OK when I did mine I installed the two wires from the ICM to the distributor connecting orange to orange and purple to purple. Did not use the factory wires. Which by passed the computer control inside. If you look at the pictures. They do not show the purple wire as being there in the first place.

Ok here is a picture guide for you.

This is what I've done. But my question still stands as to where people are saying there are 2 orange wires running through the firewall.

Hey there....My son did the same thing to his '88 and then it wouldn't start...nothing, not even a click. I ended up changing the ignition control module (on the driver's side fender). that was it! I guess the ICM just happened to go out the same time we did the nutter. He found his ICM at the junkyard for 8 bucks off of a J10 Jeep truck. the new one at Checker Auto would have been like 60 bucks or so. His Jeep is still running just fine. Good luck...

I did not T the wires, I cut them then made my own jumpers to go from the distributor to the ICM. You have to do a better job on your wiring. All that copper showing is going to give you more problems. And solder the connections, as said before.

Do not worry about the two orange wires going through the bulkhead. Take the orange wire at the ICM connect (with another wire )that to the orange wire at the dizzy. then do the same with the purple wire add another wire to the icm to the purple wire at the dizzy.


Quit making this harder on your self just follow the instruction.

There is no T's connection. Now this is not that hard to do There is no green black wires in the bypass that needs to be changed. Reconnect any other wires you have spliced into or cut.

The purple wire comes of of the ICM does not come through the connector at the ICM.

This would be my suggestion as well. Not knowing what year your rig is this may not be the case, but on my '90 the wires changed colors inside the loom so orange at one end was not orange at the other, so double check that you've actually cut the right wires to begin with.

On an unrelated note, you do realize that the Nutter Bypass effectively eliminates your smog equipment and is not CA compliant right?

When I did mine, I left everything "looking" stock so I didn't have any issues getting it smogged.

XTremjeep, I was told to T into the wires and run jumpers from there so maybe thats my problem and I didn't want to solder the wires until I was sure that I had this correct.

Dodger as I've said before this is the current setup that I am running. I was concerned about the two orange going through the firewall because those were the instructions to follow, I didn't want to miss anthing.

Timatoe I do realize the ramifications of the bypass, I've heard that people have still had luck passing smog inspections even after the bypass. I can only hope.
