Pins can partially back out of the housing & can be very hard to detect. 
One mating connector might not make contact on the problem pin and 
another might work just fine, due to differences in brand, mfg 
tolerances, etc.

Also, either the shell of the connector on the cable or the panel in 
which the chassis side connector is mounted can prevent full seating of 
the connector.

Can you get to both ends (inside both components) to probe for 
continuity from pc board to pc board with an ohm meter? Don't forget to 
remove power first (right, Bernie?)
