Help!!! 98’er Volvo V70, cylinder 3 does not run 🙁

Hi guys, I’m going to be short, it’s going to be long enough: Volvo V70, 1998, 2.4, 144 hp, switch, Km: 340,000 We’ve been driving this faithful sweetheart for about 5 years and for 240.000 km. I started to buy him some goodies a few weeks ago: Then it started: Cylinder No. 3 doesn’t run! : The engine is running. However, quite restless. If you pull off the spark plugs or injector plugs of the individual cylinders, he does what he should and goes to his knees. Achso, Funke is there and the injection nozzle pulled out also smells like crazy So, I am at the end with my Latin. Maybe someone has an idea here… Another thing… where does the injection nozzle actually get its signal? Can it be that this comes at the wrong time? Greeting from Karlsruhe Ulli PS: And if someone needs a 4-cylinder Volvo V70, he can also report
