Post "nutter" problems. Help Please
Tonight decided to do the nutter on my '90 4.2. Everything went fine until I went to start it to do the timing. The post I was following was on Jeep Forum and I was able to follow it easily. It advices to start it and get it to running temps the shut it down. Then pull the vac line from the distributor and plug then perform timing adjustments.

I can get the thing to turn over but it wont fire up at all so I can set the timing. Is the timing far enough off now that it won't allow it to start? Is there anything else that could be causing this. I'm a little nervous now since I've read running the engine in a poor timing setting can cause damage to the engine. Any help will be appreciated.

P.S. I did a search here prior to posting. I'm sure I've seen something before but wasn't able to find anything.

is this the way you did it ?

This is a Picture Guide to Nutter Bypass -

give me a call if you want.

you can turn the dist. little to get it to start if you need to and set the timing
as soon as you can .
you can readjust it as it warms up.

the nutter by pass is a great thing to do .
you will love the difference it makes.

I followed that for the wiring but there is a thread on Jeep Forum titled "how to nutter bypass" or something very similar to that. There was a picture guide on wiring and re-routing the distributor vac line to the vented port. I followed that one until I hit the "not starting" problem. I'm sure I'll enjoy it after I get it going. I've had so many problems with idling stalling and starting I'm beginning to think I'm never going to get it right.

Just test a plug and I'm not getting spark. Can that be wiring or is it going to be something else?

make sure you have good connections in the wiring job you did.
and make sure you really did use the right wires.

just to be sure.

if you did then i would replace the distributor module .

Checking the wiring now. I'll let ya know.

K guys this is going to sound stupid but I'm beginning to confuse myself. Do I attach new wire to the purple and orange wire coming from the module attached to the wheel well or to the purple and orange coming from the plug that use to go to the module? Am I bypassing the module or the wire plug part?

Alright I found the starting problem and that is fixed. However; I get the thing started and it will run for about 15-20 seconds then the idle drops and it stalls out. Holy crap what is wrong with these things that they just refuse to run???? Pretty sure I'll be calling Scott tomorrow but suggestions as to where I go from here will be appreciated.

Just so you know what I've done since I got this heap. Replaced the Cat Converter. But a rebuild kit in the carburetor which seemed to go pretty good but who knows I am new to this mechanic stuff. Rewired for the "nutter" and rerouted distributor vac line to ported vac line "T-ed" it in then plugged the hole. I have re-set timing to about 9 degrees when I curb idles consistently.

Let me know what I've done wrong guys.
