The truck ran fine in the driveway on a new 3-week old build until yesterday.

Started with a "breath" on the key.

This morning, there was =no spark at the plugs. Turned over, and over and over. Plenty of gas in the carb. Not even a "pop"! With the key on, there's constant voltage at the HEI plug.
And there's power at all spots I checked from the fuse box out to the HEI. I didn't measure the voltage.

Yesterday, I had a horn problem....And, with the help of Forum Members, fixed that...It was a problem at the horn ring.
I re-pulled the wheel and checked all the stuff I did yesterday, looking for any possible connection to this problem.

Main question(s), aside from looking for a couple of , "Hey, Magwa, check this....", is if there's power at the distributor plug, and no spark at the plugs,
could it be anything else but the distributor?

Earlier shot:

If no, what if I pull the top part (coil, I guess) and replace that? Does that make any sense. Is there a reason it would fail from perfect to no-go overnight?
