68 Charger Crank and no start

[ZDECKICH]

So was driving to a car show this past weekend and the car left me started in the side of the freeway. Was driving completely fine for 20min and started to backfire real bad and sounded like the timing just went completely off. Turned it off and pulled over.

Got it towed home and started to mess with it. First I thought there was no fuel, but pump works great and getting gas in the carb.

Put a new coil in it as I already had one, and no luck. Took the distributor cap off to look at the rotor and to inspect and all looks fine. Replaced the porcelain/ceramic ballast resistor as I had one and no luck there.

My question is, what’s next that makes sense? Why running just fine to not running at all? Ignition module or ignition switch?

Thank you all for the help.

Side note, car has a complete new wiring harness from Painless installed by them and drove it a few times since it’s been installed.

Do you have power to the coil? Are the points opening? Is the distributor turning when cranking?

I assume it didn't start when you got home. Amp gauge working? Me I'd hot wire to see if it runs, only run it for a few seconds if it starts.

Yup, check for power to the coil, you have points & condenser so no ignition module to fail.... But that condenser looks suspect....

Yea I’m thinking of changing the points and condenser tomorrow.

Check for voltage first.. Like Fran mentioned, hot wire it temporarily... Wire from the + battery post to the + side of the coil... That'll tell you if it's in the car wiring, the ignition or some sort of mechanical issue...

Point gap or condenser?

The Painless harness might have become a Painful harness......

You need to check voltages & do some part swapping....

Hard to tell from pictures but it looks as though the distributor lobes might be dry?
Worn wear block on the points?
