This is only me but I'm suspecting that the 0.12V DC measured on the injector- at the pre-crank position fools the system to think that the IDC is 100%. That's why all three leds lit constantly. Could try a large capacitor (10000uF) in series with the injector- to block the DC.

But I don't understand why the system is not working when the car is started. Everything seems to be working ok but the nozzle doesn't output anything. Test with the SYS linked proves that both the pump and check valve are working.

Could it be that the output of the nozzle is so weak at low IDC that it isn't visible? I will take the car on the road tomorrow so that I can engage higher IDC.
