My replies in red...

- All the green leds on the HFS-6 controller should be
lit with the exception of the green connector.
FAIL. RED CONNECTOR, F-IDC, THRES NOT LIT
Richard: This statement is referring to the green leds on the RJ connectors. Not the red led on the controller board.
Update: The green led on the red harness on newer HFS-6 monitors the flow sensor's turbine movement.
Steve: OK so should the red socket led be lit green? If so, this fails. In the TST test both the red and green led light up on the red socket.

3. Start the engine and let it idle for a minute or so:
- The green led on the controller should flicker
FAIL. RED CONNECTOR, F-IDC, THRES NOT LIT AND NONE FLICKER
Richard: Not until the green wire is detecting the fuel injector IDC properly, it will not flicker. Tell me how go went about connecting this wire to the fuel injector (-).
Steve: Basically connected to the "other" injector connector (i.e. the one which fails the continuity test between injector leads).

- The yellow led on the ?green? and ?yellow? RJ Connector
socket should flicker.
FAIL. LIGHTS ON , BUT NO FLICKER
Only the yellow led should flicker, green should be solid. This is further proof that the IDC is not read properly if the yellow led does not lit up of flicker. Test the green wire of the yellow RJ connector by grounding it momentarily. You should see those two yellow leds light up.
Can you clarify which "those two yellow leds are"? on the board?
UPDATE: Sorry helps if u read the question - I understand which two leds - I will test this but they do light up in the test. Neither flicker though.

- Flicker should speed up with engine speed.
FAIL. LIGHTS ON , BUT NO FLICKER
The green led on the yellow RJ conenctor socket should be a solid green.

Can you clarfiy wether the yellow socket or the green socket led should be static and which should flicker?

From above
Only the yellow led should flicker, green should be solid.
The green led on the yellow RJ conenctor socket should be a solid green

In the test, both illuminate but neither flicker..

What about the led lights on the board which should light up on this test?.
