My Jetta 2 with a Golf 3 GTI 2.0 engine does not start.. :/

Hello to all those who are on the road here, I need help and tips with my Jetta 2 which has an engine from the 3 Golf GTI 16v 2.0 in it. It does not start, does not get a spark despite the replaced ignition coil, and the second thing is that it does not get fuel but the petrol pump is running (have already replaced the relay) the engine turns when I start it but there is no spark over the spark plugs completely cleaned and kept to the engine block when starting, there was also no spark. I guess that it might be on the control unit but wanted to ask before here because the community here has some more experience. In addition, that is my first car and I have hardly any experience with golf. Any help would be top ?
