I have two nights on my D.U.I (HEI) distributor. I have a strong 12.46 volts at the cap. I swapped out the coil and cap with a spare. No improvement. Could the module have failed already? A very weak spark is present. What am I missing here? Thanks.

make sure you have a very good ground to the engine block.

12.46 volts isn't even fully charged, 12.6 is. Either run an alternator or 16 volt battery. This is probably not you're problem presently, but it will be in the future.

I run into this problem years ago. I found that I was not getting proper power supply to the distributor.
