Default Car Will Not Start--No Apparent Spark

It doesn't sound as though you checked the points closed for no power. Clean the point contacts and check that the distributor set screw and jam nut is/are snug.

I think I posted earlier that both sides of the coil have power. I checked again, and I see 6 volts on both sides of the coil.

The driver side of the junction box gets 6 volts. The passenger side gets 0 volts. Putting a temporary jumper across the junction box studs reduces the voltage to near 0.

I checked the jam nut, and it’s tight. I don’t see the correlation of the jam nut to not having spark.
