Ignitor Woes
Okay, I'm driving to work yesterday, and all of a sudden, theres a power loss, difficulty getting up to speed, and an idle of around 500 rpm. Car was backfiring a lot anywhere above 4000 rpm. So, I take it easy to work, and after my shift, the car starts up, but still under the same symptoms.
After I get home, I pull out the timing light, and unbelievably theres no spark going to the leading plugs at all! I never thought I could run the car on just trailing.
I tested the coils with a multimeter, looked to be fine. I pulled off the leading ignitor and tried the test in the Haynes manual, it failed.
Anyway, I went to the junkyard, and found a pretty un-molested SA, and pulled out the 2 J-105 ignitors.
My question is, Can I use the J-105 Ignitor in place of the blown J-109. I understand the length is different, and one of the mounting screwholes is further down, but I can make that work. As long as it works at least temporarily so I can start driving my car again.
Thanks,

Dark Frost i have a few used Ignitors the smaller ones you are looking for....$10 each plus shipping... Grab your old ignitor see if you can fix it just remove the backin piece and see if you see something that might need soldering.

I was thinking about swapping the trailing out, but I dont have one of those funny screwdrivers, and dont really feel like pulling off the alternator to get to it. I'm gonna try the J105 and see how it goes. I'll let you all know how I do after I get home.

lol.. the bolts are so rusted, I'd rather just leave those there.
BUT, the good news is, the J-105 works! And, if it craps out, I still have another J-105.
So, all is almost well again. I'm setting the timing now, and am gonna re-tune the carbs, make sure they're in sync and everything.

I will say that I have been using gm iginitors on one of my 7s for several months now with equal, if not better performance than a j109 and when my supply of j109s dry up, I will change my other 7 over. There is something about a $13 ignitor w/ a lifetime warranty that appeals to me.

Ask a parts store for an ignitor (ignition module in the computer), and its a Wells Ignition Module for a 1979 Chevy Nova. Around $20 each or so, as I have read.
