No spark
I have no spark at the plugs. I used a screwdriver to open the points and have spark there and can hear spark at the coil too. This is a 54 F-100 6 cyl. What should i be doig next?

PM - You've got to figure that the problem is between the points and the plugs. While it is not likely that the wires all went bad at the same time (you did check spark to more than one plug, right?), My guess is that it is in the cap. Either too much gap between the rotor and the cap, or the cap itself is toast.
How big a spark do you get at the points?
I know these electrical things are frustrating. You just have to take the time you need to rule each element in or out of the problem. I would just start replacing each item. New condensor, points, rotor, cap, etc. Many of us can tell stories of how we had to go thru something one piece at a time to find where the break was. That's how I wound up with so many spare "good" parts. They weren't the problem.

Check the screw that goes through the distributor, the one that the primary lead from the coil hooks to. On the inside of the distributor there is a piece of plastic that insulates the wire connection from shorting againist the housing. If it's cracked like mine was there will be no power to the points.
