Ignition help
 
So I have an 83 Gsl and I just recently installed dual 36 dcds on it. This question will have kind of a long back story so bear with me. I installed them and tried to fire it up only to find out that I had no leading ignition. I swapped the igniters and it started right up. It doesn't run well so I figure thats bad ignition timing and a bad ignitor (which is now on the trailing side). So I ordered a used but tested ok igniter from mazdatrix and figure it would be an easy fix. I installed it and hooked up a timing light and I still have no trailing ignition. Im almost positive mazdatrix didn't send me a bad ignitor and I confirmed that the problem was an ignitor in the first place. Any Ideas or advice? The only thing I can think of is that the back of the original igniter has a coating of dielectric grease on it from the factory….the back of the mazdatrix one is dry. Could it be it is not making contact from the lack of the dielectric grease? Thanks for reading my long, drawn-out sob story.

What's the condition of the dizzy? Maynbe a bad pickup? Idk much about ignition but if it was me I would also re-verify that everything is connected properly (grounds, etc) also I would test the ignitors manually just to make sure they are both good. I've used them both dry and with dilectric grease and they have always worked either way so I doubt that is your problem.

Its just strange that when I switched the ignitors initially when the leading stopped working it fixed the problem. Thats a pretty cut and dry ignitor problem to me,

Hence why I suggested testing both ignitors to verify they are useable.

I just did….It turns out mazdatrix sold me a 90 dollar useless piece of plastic. Im gonna have to return it.

I have a few ignitors laying around. If you want I can test them and find a good one for you. Just let me know if you are interested

Make your own igniter tester...its very easy to make.

Ignition switch still work? When you turn the key on, do the coils light up with 12V?

I recently had to take an igniton switch apart. Clean and grease the contacts. Now it works.

maxwellt91 12-10-13 04:46 PM

the ignition switch and both coils are fine. And can I pm you about sending me an ignitor rotornoob? Im very interested
