OK update. Thanks my cars!

Confirm no FV buzz.

It would appear I am getting no power to Lambda circuit at all. No power to either relays under the seat. ie Speed relay and O2 Control unit relay. I am also not getting any power to O2 heater. O2 sensor has 6 ohm resistance cold.

Both fuel pumps are running, swapped relays around just in case.

I am now wondering if we have a open circuit between fuel pump relay and lambda circuit?
