Just picked up a 93 s4 and it wasn't running. The problem listed was bad ecu. I've gotten the car to turn over fine gets fuel but no spark. Was wondering if it was more than likely a icm problem? Or any info is helpful. I will be swapping them with some b5 s4 icms Tomorrow. We'll see what happens. But cell comes on and all dash lights. Radio doesn't come on was told windows were open for a few months https://uploads.tapatalk-cdn.com/20170930/b71e209f8e675dbc81d5a174d198baf4.jpg

No spark can be caused by cam or crank sensors. Also the items you mentioned.

Replace cam sensor as next step to report back. Alternatively, use VCDS to watch rpm as you crank it
