I have a 1990 audi 100 2.3L 5cyl. The problem I'm having is that the sparkplugs won't fire. I first thought that it was the ignition coil, however, after I replace the ignition coil, it STILL wouldn't start. Then I hooked up my timing light and it won't flash because the sparkplugs (which are maybe a year old) don't seem to be recieveing power. I'm EXTREMELY confused, PLEASE HELP ME!!!!
