Pneumatics Help

Vexing pneumatics problem ...

Have 5 festo M7 2 way solenoid valves in a gang ... all are singles. All are hosed and wired in similar / same manner.

We are having trouble with one of the 5 valves:
- our code can change the status light from a side (extend) to b side (retract)
- the manual actuation can physically change the output of the valve from extend to retract
- when we change state with code through the solenoid breakout, the light changes but the spool does not seem to move
- we replaced the valve twice with no impact

I'm thinking solenoid breakout, wiring but I cannot explain the light changing state but no apparent or observed movement in the spool.
