I recently had trouble with starting my A4. When I pulled a plug to check the spark, I found that I was only getting a spark when the starter motor was disengaged and the enging is still spinning from its momentum. While the key is engaging the starter motor, there is no spark. My voltage at the coil is 10.4, during cranking. There is no resistor between the battery and the coil, but there is an internal one in the coil.
