HEI upgrade, wont start (no spark?)

For starters the orange box setup is electronic not HEI.

Check the reluctor gap. You need a brass feeler gauge.
Right, my mistake, named the type wrong.
I will double check these.

If using HEI ballast resistor is bypassed.
My mistake, it's not HEI.

Did you try putting you old coil back in?
This thought occurred to me as I lay in bed last night lol. I will try this.

OK, assuming that all the parts you received are functioning, follow this diagram.
The simplest way to determining which (original wiring) lead is which Run vs Run/Start, is to unplug one end of the original ballast resistor. Put the ignition key in Run, and then test to see if the unplugged end is hot or not (with a meter or test light). If the unplugged end is hot, then this is the 'Feed' (Run) wire to use for power to the ignition module. Also, you HAVE TO GROUND the case of the control module. If, after checking this, you still do not have some sort of spark-then I suspect a faulty control module or distributor pickup. The more likely culprit would be the module. You can ask for an ignition control module for a 1976 Dart or Volare (any engine size) at any auto parts store and this should get you the appropriate module. Just an FYI on modules. If your original module has 5 pins, and your system is wired for this, the replacement module may only have 4 pins. The 4 pin module is a direct replacement for the 5 pin modules and will work with NO Changes to your factory wiring. You will notice on the attached wiring diagram that the fifth pin is not even connected.
Jus sayin
That diagram matches what I drew up from reading the instructions. I have confirmed the "feed" wire multiple times. The only wire I am not 100% sure of is the wire from Coil+ to the start side of the ballast resistor, I assume this would be the existing wire at the Coil+ and already runs from the Coil+ to Ballast Start side. I will use a multi-meter to confirm and will run a new wire if needed. I will also try a different ground source. If that all fails, I guess I'll go try a new ECU, looks like maybe $25 at the parts store.

Thank you all for your help! I'll try these few items when I wake up a bit more :thankyou:
