Thank you, Vitesse and Yorkshire GOC! I see that I have made 0 thanks. Pardon me, but I just don't know how to thank you?

Thanks for the heads up about Beinet 1, my fellow Norwegian. Good to know!

Yes, I will have another go at the fuel filter, like T-Cut suggested. (I just hope the tank is not too full now. After fitting the filter, I added 3 liters of fuel, as I understood this was recommended after having done the change).
I'm also gonna check the fuel pressure at the rail today(think I found the Schroder valve), but not sure if I could check the pressure by myself, or if I need someone to crank the engine while I measure?

Yorkshire GOC: Yes, the rev counter moves a tiny little bit during cranking, so if the crankshaft sensor was the culprit it would stay totally still at 0, I assume? Thanks!
I also have a new replacement camshaft sensor, but I was not able to figure out where it's located. Searched, but just could not find a picture of it that I understood... Probably basic knowledge, but beats me..
