i have run used bmw 318 1986 coil and golf gti coils on mine just to eliminate the coil from my then inquiries both ran perfect once i could bolt it on.its just a 12 volt coil nothing special about it.don't lose too any sleep on this one with the fine print.

Gunnar, did you find the big white ceramic resistors?
I have a spare set if you find that yours were removed.

If you mean these I think I'm good for now. Thanks

Looks like your PO was a PepBoyz mechanic.

A coil's a coil - slap it in there!

Same thing with too small battery, too low press fuel pump(both since replaced). Both were brand new. It looks like he got the new starter right though.

YES BUT THE RIGHT PARTS WERE TOO EXPENSIVE ! I am going to buy an expensive limited production car because it was expensive and looks it but I aint gonna pay big money for the correct parts.....

One of the joys of CDI ignition is the higher net primary voltage available, and therefore the higher secondary voltage available. Yes, one terminal has 11V on it running. Measure the difference to the other side of the primary with an oscilloscope when the car is running and let me know what you see. The whole principal of the CDI is that there's a solid-state switch and a capacitor as a voltage multiplier. A standard 12V coil isn't up to the task; higher primary current means higher heat, and the insulation melts. Most coils are oil-filled, with many early original pieces using PCB's in the oil, so use appropriate caution when handling leaking coils.

Dr. Bob,
I have the correct coil now as PET specified but it looks to be the same as my old coil. Can you clarify please. Gunar..... new coil here 928 602 503 00

I changed the plug wires,plugs,coil,cap and rotor and the problem persists. I will do Sharkskin's ignition troubleshoot and if that checks out move on tho fuel pressure check. I just knew the coil or the plug wires would fix it and turn out like this thread> https://rennlist.com/forums/928-foru...on-issues.html since I have identical issues. I don't have a temp II sensor on a 82 Euro S right?

Coils are so fickle. I always think it's them when intact a running issue, but it never seems to be After all.

did you recheck cylinder compression since ?

I think it might be a STD and you should see the Dr

just had to sorry

928 coils seldom fail......16 years of selling 928 parts and few coils ever fixed a no start condition.....You can easily determine if you are missing spark or fuel. That narrows down the possible causes. Shoot some carb cleaner into the intake under the air filter and see if it fires when you crank it.
