Sounds like there's no throttle signal. To test this, measure the voltage between the signal (_Π_) and negative (-) pins on each ESC port. You should see at least 1.3V at low throttle, going up to about 2.6V at full throttle. If it is stuck on zero volts then the Naza is not sending out a throttle signal.
