I have a new problem this week. The liquid fuel stop solenoid 20FD-1 did not open when the logic L20FD1X is forced to ONE. This is done on weekly basis to prime up the liquid fuel line.

I have tried to replace the solenoid with a new and the result is still the same. I did try on the other unit which works well (so far ;)) and the solenoid operates without any problem. 

The solenoid is connected on SO17 on the DTBC on
