Thanks for you input guys - however I have spotted the problem now ;-)
I have a new ignition switch installed ½ year ago, now I have checked the starter and solenoid - they work fine. I can hear the starter relay clicking when cranking the car.
I couldnt get power to the purple wire on the starter, so I followed the wires back in the car - removed half the instruments panels etc for checking alle the terminals etc, and everything looke fine !?!?
so after pulling my hear all day I accedently discovered the the wireloop didnt bring power to both purple wires, and I did a new wire loop between the 2 purple and the cars starts perfect :-))))
I have ordered a new neutral switch, so tomorrow EVERYTHING goes back, AND I am a hole lot weiser in how things work and look from the backside of the dashboard ;-)
