Spark problems need help

I need some help I am doing a straight six to v8 swap the car was running great before so I don't know why I'm having problems now the car had a straight six with electronic ignition I put in a 302 and added electronic ignition on that distributor and now that the motor is in I am getting very little fire out of my coil it's not bumping me up to the 12v on cranks so I'm not getting enough fire on start up nothing to the spark plugs I've replaced ignition switch and all wires seem to be making contact but is there any way my resistor can be stuck or shorted out I have great fire going in to the coil but very Lottie coming out to the coil plug wire any advise is greatly appreciated thanks.

Another one sentence per paragraph guy. (he shakes his head). Did y'all flunk English? At least make SOME kind of effort to punctuate your post for ****s sake.

Try putting 12 volts directly to the coil. It's my understanding that electronic ignition systems don't use a ballast resistor in the circuitry.

Yes I have done that and status does not change. I've also tried it off the starter solenoid.

If you got 12v straight into the coil with good connections and earthing and nothing coming out, that would indicate a crook coil - to my way of thinking.

Took me a while to work out the complaint!

As it is an electronic ignition setup, the coil has 12v on it and much is as before, my guess would be that the ignition module is missing an earth or has a poor connection on the earth side.

Can you put an analogue voltmeter on the earthy side of the coil? You will see then if the module is doing what it ought to, by seeing the switching pulses as it cranks. If they are present, then you are looking at a faulty coil.

I have two coils that are both doing the same thing I have some power coming out of the coil just not enough. Is it possible they are both bad even with the little fire coming out of them?

I refer the honourable gentleman to the reply I gave some hours ago. ;-)

It is unlikely that two coils are faulty. Much more likely to be the drive to it. Check your ignition module is properly earthed, test the CB terminal with a scope if you have one, else an analogue voltmeter. Try changing the ignition module.

Check your grounds! More problems are caused by an improperly grounded engine or electrical system than almost anything else. Be sure the block is well grounded.

What or who's electronic kit did you install in the distributor? Double check the install, and then contact the supplier. It might have a problem in the kit.
