No Spark here.
 

After 3 or 4 months of trouble free driving my 930 died at idle last weekend. I have no spark. Elect is not my strong suit, so i'm in need of advise. CD box whines, connections from 6 prong plug all seem ok, and tested for "buzz" at all ends of the wires. Discon the tach, no change, had coil checked, tested ok. I put in a new/used distrib a few months ago. Is there any test for dummies of the distrib in the car via the green wire? Or a test to show power to the distrib and out of it. Or other items to test? Thanks. Brian

Do you still have points? Check the Gap

I think it's pointless.

What year is your 930 Turbo?

78

Is the distributor rotor turning? Seems the dist. would be suspect, but hate to assume anything at this stage.

I'll check the rotor. I suspect the distrib also, but don't know how to test. Thanks.

Check that you're getting a signal from the green coax wire coming from the distributor.

Here's a thread I read yesterday on some ignition troubleshooting.

Thanks. I know my coil works, I had it bench tested. But, I am going to pull the cap and rotor tonight and replace. Rev limiter has been making a diff sound for a while now. Still not sure if the problem is upstream from the coil.

Are you sure you are not getting a spark?

Yes, I have no spark. and I just pulled the cap and rotor. They look ok, but i am replacing.
