I'm hoping some of the pros pop in with a shorter method.
All zones, manual start?
Tedious but...
Remove all modules but first.
Remove common wire and zone wires so you have an open common screw and open zone screws.
Turn on zone 1. If you get a fault message press the (-) button to clear.
Check voltage from common to zone one. Should have 24v+.
If the FAULT message would not clear then you have possible module problems.
If it did clear and you have 24volts then while zone 1 still on check rest of zones on module.
If they are getting power then bad module/controller.
If they are not, turn off zone one, hook common and zone 1 wire back up.
Turn on zone.
If FAULT appears problem probably in field wiring.
If FAULT doesn't appear hook wire to zone 2 and test.
If no FAULT, repeat basic process as you add each wire that is controlled by first module.
That goes ok, add second module, turn on first zone on module, etc.
