No Fuel PSI, Oil PSI and Oil Temp Indications

With all switches ON (Master, B/U ECU and both Lanes ON) I have Coolant Temp and GPH displayed on the EFIS.

However, Fuel PSI, Oil PSI and Oil temperature are NOT indicating.

I have pulled the spark plugs so I can spin the prop quickly by hand to monitor Oil Pressure. But OP does not register.

Fuel Pressure stays at 14 no matter if I turn the fuel pumps on or off...

Coolant is registering at the outside ambient temp, so I'm sure it's good.

Outside of pulling wiring harnesses apart to test for connectivity, is there anything I can look for?

- I am also receiving a Lane B Sensor notification, which would seem to be related (pic attached).

- I also have NO Lane Lights with B/U ECU switch ON, and both Lane Switches ON
