Try putting a points plate back in with points and condenser. Set your dwell angle to 33 degrees. Could your new Pertronix be faulty? If you have correct timing and firing order, good gasoline, and compression- THIS THING WILL FIRE UP AND RUN.
And where are you located?

I meant to also say "good ignition" THIS THING WILL...
Forget that this is a Corvair and work on it like it is a car from the 60s. Very basic. BTW my spark tester is a spark plug plugged into a plug wire. Aftermarket coil?

Do you have a tach hooked up? Disconnect it from the neg terminal of the coil. They can short it out.

P.S. Not the problem, but pull some of the black and red Pertronix wire out of the distributor, so it doesn't rub on the cap.

I believe the same is true with my '61. I left the Distributor semi loose and advance it as it's trying to start, then look for the sweet spot. Worked for me. I also removed the Pertronix and went back to points.

new spark plugs gaped at .35

Only the 95 horsepower engine is a .035" gap. All others are .030" gap. But I doubt this is your current problem. It should still fire up.

And so what about the way the Ignitor is connected? I've been wrong on the Corvair connections before, but I thought that the Ignitor-I needs the 12v to the Red wire, but the ignition coil still needed to use the ballast resistor. Correct?
And that looks like an older coil, so could perhaps be stock? Someone asked if it was aftermarket, but either way I would think knowing what the coil's ohm rating is would indicate which wiring scenario should be used.

With some setups, would it not be necessary to feed the coil through the original resistor wire, while sourcing ahead of the wire for the Ignitor to ensure the full 12v?

Sorry if that's incorrect for this setup, but every time I see the Red wire connected to the coil positive I think about it.

And yes, since there seems to be spark at the plug wires, the Ignitor and ignition coil would seem to be working as well. But nothing "normal" explains why the spark would make it to the end of all six plug wires, but not pass through any of the six plugs.

The ground strap is missing on the Pertronix.
All of my Pertronix 1 units are connected through the resistor wire and they run fine.
Disconnect the Pertronix from the coil and then intermittently ground the negative side of the coil. It should be able to fire a plug that way. If it can't you have a bad coil, wire or low voltage to the coil.

put in a new coil tried again still no spark at the plug only for some reason. i found when the rotor is on a point it will send spark to the plug fully but when turning the engine over no spark at the plug. installed a new ground strap to the engine block also to ensure proper grounding is there.

Must be a bad Petronix? How to test it instrutions are in our FAQ's

So I Ordered a stock distributor with points and will post what happens after installation. Thanks for the assistance guys

That sounds like the rotor is out of phase with the module. It's firing when the rotor is between the towers on the cap.

We hope you are able to figure out what your issue is. Please post the solution for our library. That may help someone else down the road. Many of us have spare parts. That is why I asked you "where are you located". Sometimes our spare parts are helpful in diagnosing tough unusual problems. Buying parts to diagnose is 1 way to fill up your shelf. At least mine- I seem to never guess right.

Make sure there is 12 volts at the coil, WHEN the engine is turning over.

There won't be. Battery won't put out 12V with the starter load.

Hence why this resistor and bypass during cranking was invented. So the coil sees the same input voltage when running or cranking.smileys with beer

Is the resistor wire still installed? If the coil and pertronix are feed voltage through the resister wire (which is normal for the coil only in the run condition only) then the pertronix will receive ~9 volts when current is flowing. This is marginal at best (ask me how I know). The tricky part is that when current is not flowing, 12 volts will be read at the coil because its the current flow that causes the voltage to drop from 12 to 9 volts.

I wonder what the issue was for this poster imautorepair. I sent him a PM asking him to post the solution but never received a reply.
