The idea is once i have this running , i can server zabbix. But the struggle is hard :). Have to start first with a working nginx+php_fpm+tcp(no socket) , working configuration. Any guidelines to debug ? checks ?
 
there are several things to check, or add to your problem.

You have an index order, any change you have index.html/htm and index.php in there?
there is no need for an 'alias' in the .php block

Code: 
    location ~ \.php$ {
        try_files $uri $uri/ =404;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
        fastcgi_index index.php;
    }

But above all, you forget to mention what actually happens when you do request a php file. e.g. a phpinfo.php with <? phpinfo(); inside
 
Nginx is very chatty and specific about errors - check the logs.
Same goes for php-fpm - check its logs. Is it even running? (-> sockstat -l)
Also: for local connections just use unix sockets, they are faster and also work in jails that don't have their own loopback interfaces (e.g. non-vnet jails).
 
Currently nginx serves php,
I give my config file,

Code: 
cat nginx.conf
user  www www;
worker_processes  auto;

#pid        logs/nginx.pid;

    keepalive_timeout  65;

    #gzip  on;

server {
listen 80;
    server_name myfreebsd; # Change to your domain name or IP address
    root /usr/local/www/nginx; # Your web root

    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ =404;
    }

    # This block processes PHP files
    location ~ \.php$ {
        root /usr/local/www/nginx; # Ensure this matches your web root
        fastcgi_pass 127.0.0.1:9000; # Use the IP address and port here
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
