Audi 80 2.6 V6 does not start, no spark

Hello, I have a good old Audi 80 2.6 V6 with Tartarini gas system with approx. 300T km before the Gnachtot and bought it for 250,- Euro, because I have courted him to get to run again, because he does not jump anymore according to the previous owner. Now it is so, the previous owner has already played something on it, but he did not get to run and therefore advertise him again, statement of him he probably did not jump from today to tomorrow and stood now about 4 months. n good now with a hanger brought to me and made me on it, so much I can say. 1. Engine rotates perfectly through when starting. 2. Engine has full 14 bar compression on all cylinders. 3. Spritt comes, pump promotes. 4. No spark of ignition available. What I have done so far. Candles, cables, ignition coil and the ignition coil control unit exchanged, nevertheless no spark of ignition. The previous owner also said to me to have exchanged the reverberator, but this I close as a mistake s, because if this is defective, the fuel pump should not work either. I’m slowly ending up with my Latin, and wondering what else it might still be, does anyone still have a suggestion what it might still be about ? mfg
