Zj 97 5.2l

Hello, I have a problem with my zj that forums in Norway cant help me with. Therefore I have to try this bigger forum for help.

The problem is that the car will not start unless the gear box is in Neutral and the brake pedal has to be in. After start it runs good and can be used as long as the brake light switch is engaged. If I let go of the brake, the engine dies.
Have changed brake light switch and most of engine sensors, but the problem is still the same. No codes in the display is telling me whats wrong, the engine is running perfect as long as the brake pedal is in
There is a blinking after start in the on/off switch for the electrical overdrive....don't know what that means ???
Have tried to search on this forum for the answer, but did not succeed.
I really hope you guys can help me, I really love this car, but it has not been out on the roads for the last four mounts due to this problem.
Thanks in advance

Took of the connection on the NSS, and then the engine would not start at all.
cleaned with contact spray and put the connection back on, and then the engine started as usual , in neutral and brake pedal in.
As soon as I let go of brake pedal, engine dies.
How can I rule out that the problem is this switch ?
Is it possible to over ride this switch ?

Are you sure the new brake switch is good?

Hi again, the brake switch is brand new from Rock Auto, but I can of course not be 100% that its good, I just have to assume so I guess.

Was out test driving today. Keep the brake pedal in so that the brake light switch is engaged the car runs smooth and nicely. When I let go of the pedal, the engine dies and check engine is to be seen in dashboard.
All lights at the stern is good, brake lights,tail lights and backup lights.
Can it than be the NSS ???
There is some blinking in the on/off switch for the electrical overdrive, what can that be ?

This problem is really getting on my nerves,hehe
Hope somebody can point me in the right direction.
Have in order a new NSS just in case
