How did you test for spark? Why did you replace the igniter? I can’t with good conscience tell you to replace the distributor, because I’d be surprised if that was the answer. What wires are bare? The spark plug wires? I’m confused man.
It just occurred to me that you replaced the igniter and the coil, so you’ve replaced most of the internal parts of the distributor itself anyway. Were wires damaged when you replaced the coil and igniter?
