The issue is solved!
It was the hall sensor in the distributor cap all the time!
Now the engine puls like a 8-valve should do...
It did not give any warning ever, until it quit entirely...
The mechanic could not swap the sensor itself, he said something about something broke at the inside so he got another one from the scrap. I did some research myself, as far as I could find you can buy a new one, but they don't come cheap or it's China made.
There is so much to be found on the internet this hall sensor is a little problematic...
So if it breaks, there is no spark and no fuel coming out of the injector!
I changed almost everything.
The parts are cheap, only the idle valve "sensor" was somewhat more expensive. All in all I think it costs me about 150 euro's or so, and the spark plugs and leads + distributor cap (with rotor)+ new battery about 200 euro's, so now it's fixed and it had a good old service also!
