76 Dodge dart wont start

Great. Sounds like you used the 4-pin HEI module. I put the 8-pin HEI in my Valiant with the GM coil. For the future, get an in-line spark tester ~$5 at HF. If spark and no fire, I spray starter fluid in the intake. On newer cars, the culprit is often the electric fuel pump in the tank.

I'm not exactly sure what was going on I had spark but no fire, I tried starter fluid and putting gas in the bowls no fire. However the minute I put the 4 pin HEI in there got rid of the Mopar Ignition box it fired right up.

I am 100% sure it wasn't the ballast resistor I used my ohm meter and it tested within range. On the ignition box the grounds looked good but I regrounded it anyways and none of the pins or connectors had corrosion on them. Anyone else had this problem with the ignition box?
