440 no start, any guesses guidance?

[RTDaddy]

To All,

Daytona clone, basically stock 440 with Mopar electronic ignition. Started and ran fine 3 weeks ago, tried to start ran about 10 seconds and quit. A couple of times it ran 4 - 5 seconds, but now nothing. Fusable link checks OK with test light, power to coil (11.3V) and 11.3 volts on neg coil post also (this right? neg post "hot" also)? Gap on distributor inductor coil checks ok at .008" per recommended (brass strip of course). No spark with plug connected and held to ground. Ground checks ok on motor, firewall, and radiator support. Power to electronic control module checks at 11.3V. What volts should I be looking for in and out of resistor on firewall? Any other ideas/suggestions?

Thanks to all.

Try a different ECU box with the 4/5 pin connector.
You should also confirm power in the start position but from what I read that's not the issue.

And squeeze the female connectors in the ecu plug.

give it two tablespoons of gasoline and see if it pops

Gas/starter fluid doesn't do it. apparently no spark. New ECU box tried also.

Yep, they unfortunately don't do Kegels on their own!

Electronic ignition doesn't like low voltage either. If you have everything up to the distributor, rotor and cap okay? When starting, getting 12 volts to coil on ignition 1?

Ballast resistor 12v in & 5V out (???). Unplug center distributor wire & place it near ground (still connected to coil). Disconnect “double bullet” plug at distributor. Turn ignition to run. Ground exposed bullet connector on wiring harness side momentarily. Every time you ground it, the distributor wire should jump a spark to ground. If spark jump - problem is distributor (cap, rotor, reluctor). If no spark - problem is coil, ignition box or ballast resistor. Check ballast resistor continuity with nothing plugged into it. That’s the most common problem
