Thanks for the reply.
now I c why my new 3800 S2 S/C will run only for 2 secs and then stall. I didn't connect that when I started the engine for first time.
the other things I have't connected yet is 1) the exchaust system with the second O2 sensor.
2) the air filter
3) The sensor in Photo 4 (no.1) that I don't know where it goes.
4) This socket I don't know where it goes.
But I quess I have to connect this silver box again tommorow morning and try again.
If you know anything about 3 & 4 please let me know.
Thanks
Kostas
