OK. A little history. My 90 TSi had a fried coil pack so me and my brother decide that we would try to build a COP for it. It took about four different tries because all the wiring diagrams i found weren't labeled for which cars they would work on. anyway finally got the right diagram and it works. however only the number 1 cylinder won't fire. i tried 3 different coils on it and none would work right. I put a spare plug in the coil to see if it arcs between the plug and engine to check if it works and it will spark fine, but as soon as i actually touch the plug to any metal the spark goes away. i also put in a new plug.
i tried to find the wiring diagram again so everyone would know how i wired it but i couldn't find it. anyway it came off this website.
anyone have any ideas on why only one coil will do this
