Default Injector question

My 964 is running strong. No issues at all, but...
Yesterday I used Scantool to run the injector valve test. 5 of 6 injectors produce the expected click when tested. Injector 6 is not 'clicking'.
The car is not running on 5 Cylinders, no petrol smell, idle rock solid, power up the red zone.

Should I be worried about injector 6 not clicking?

No error code related to valve not working.

Injector Coil resistance is 16ohm (which is good)
Power output connector is 12v
Did not test pulsing yet. Don't know if I need a scope or use a multimeter to check this, any tips welcome.

You need to make up a test lead (Bosch EV1 male and female plugs with a couple of wires off one of the plugs) and use a scope.

I would pulse it with a 9 volt battery first before bringing out the big guns.
