71 Berlina 74 GTV 17 Giulia Q4
Did you clean the points (I'm assuming they have points being an S2 guy) with sand paper? If so the sandpaper will leave a film on the points that will not carry currrent and no spark. Clean them off with a rag soaked in brake parts cleaner. see if they spark with they open, then see if the coil wire sparks to ground, then put the cap back on and see if any on the four wires spark to ground. Check that you have 12v to the posititive side of the coil. good luck, just take it one step at a time to track the problem down.
