22r not starting
 

Been a lurker for years and you guys have always kept my junk running. I've search a ton of info about this and still a little lost.

Anyways, I got a 84 with a 22r, weber 32/36, cap, rotor, plugs, and wires are about 2500 miles old. I was coming back from work a while ago, took the turn onto my street and she just shut off on me. Cranks fine, wouldn't even attempted to fire.

As an aside every once and a while she would die coasting to a stop. She would start back up fine, or I could bump start her before stopping and she would run fine. It would do this no matter how long its been running, or how warm. I thought maybe it was the carb being goofy but anyways..

Did the newbie thing and started throwing parts at it. Went with a GM ignition and coil as shown in some write ups. Reason I thought it was that coil was because no spark was coming out of it.

So here's where I am right now. If I take one of the old wires coming from the dizzy and tap it against the negative on the coil I can get the truck to fire, not run and sometimes back fire out of the carb.

As you can tell I'm kinda new to this stuff. Is the pickup coil bad? Is there even a pickup coil in this dizzy?

Anything you can tell me is super helpful. Thanks like always.

by "old wires" you mean a spark plug wire?

with carbed engines i used to check for spark by first pulling a plug wire, and seeing if there was spark to ground(engine block, spark plug, etc) while cranking... i think that there should also be spark from the center wire going into the distributor cap, while cranking the engine over?

Well basically it will not spark from either the coil or any plug wires. If I take one of the sensing wires off the dizzy and ground it out to the neg on the coil the coil will then send a spark. Otherwise no spark happens.

i don't know what a sensing wire is, i have 22re tho... way back in the day, i've seen people run a hot wire from the battery to one of the coil terminals, don't know that i'd try that here.

the factory manual will have a troubleshooting sequence for the factory ignition.
