No spark at coil

Yes if the ballast resistor is burnt out then it wont flow any juice. I think anyways. There what, like $10...why not? You already have tried everything else. You will have an all new ignition system when your done. I had a similar problem. I bought a new ECU, rebuilt the dist., new ballast resistor...the only thing I didnt change was the coil because it had spark. Not alot but it had spark, finally said what the hell bought everything else might as well buy a coil. Sure enough fired right up. I personally hate electrical stuff. It seems like you just chase problems forever lol
