Well, I repalced the normal tune up things on a car. So then I went to start her back up and she wont start. It cranks and gives fuel just no spark. So I then tested the coil, and it was shot. I also replaced the ignition module while I was at it. I wrapped everything back up and tryed starting it, and it will not start. I hold the #1 plug wire up to something metal and have someone turn the key, and I get no spark. What would be the problem? The car was running before I did the tune up.
