Suzuki VZ Marauder 800 – 1997 ?

Good evening, everyone. My sweetheart (VZ 800, Bj 1997, 20tKm) is currently presenting me with problems and maybe someone can give me a hot tip here. She doesn’t start anymore; the reason was the last exit last year. After a few kilometers I noticed (first) that the start switch was stuck and the machine started permanently, or at the turn-off it jumped again and again. When I could finally release the button, it didn’t jump any more. g it again, however, it went out at every traffic light again or as soon as it only ran in the stationary gas. The drive home was an ordeal. It needed several starters from the car. I have overtaken the switch now, should funzen; battery came new; starter came new; petrol pump came new; magnetic switch came new; ignition coils came new. Nevertheless, it gives no more mucks of itself, only the petrol pump starts up – until pressure is built up. Starter does not matter, unless I go directly to the Battery – but not enough to start – but he turns. I am finished. Does anyone have an idea here? I would like to “execute” my sweetheart again.
