Make sure that the 1 PPS output is enabled... It can be turned off by software and that mode can be set in EEPROM.
Also, many scopes have great difficulty showing a 10 uS pulse at a 1 PPS rep rate. Digital scopes might not sample it in normal display modes (envelope or glitch capture mode can help). It can easily get lost on an analog display... _________________________________________________________________ Your E-mail and More On-the-Go.
