Sorry I missed this by reading in reverse cron order.

1) sudo is bad Security Theater(tm).  Just be sure gpsd is run as root.

2) -F is for hotplug.  RasPi serial IO knows nothing of hotplug

3) no /dev/pps0, so of course you get no PPS.

Try this, as root: 
    # gpsd /dev/ttyS0 -s 115200 -n /dev/ttyAMA0 /dev/pps0

Where did you see that is the way to do it?  That needs to be nuked.
