Last Tuesday I drove to my friend's house and when I went to leave it would not start. I had been having starting issues lately but my car always would start eventually without changing anything. This time was different. I found out I had no spark and figured worn ignition system was the cause. I overnighted spark plug wires, dist cap, coil, and a new rotor. After installing, still no spark. There is powah at the coil. What's next?
