Just to add to the confusion....
There are two cases of "no PPS". One is that nothing is wired to that pin.
The other is that everything is wired up correctly, but the GPS device is
smart enough to mask off the PPS when it isn't valid, for example when first
powered on and it isn't listening to any satellites yet.
After you get going, there are still two cases when things stop working. Did
rain or whatever cause the number of satellites the receiver can hear to fall
too low, or did the cable get unplugged?
