just checked lamda probes no earth on white wires and only have battery voltage on red wires when ignition on not when engine running obviously not right does anyone have wiring diagram for engine loom

thanks for info checked relay it is correct however when metering at relay if the fuel pump is running the 12v feed to relay is dropping to below 1v though fuel pump runs fine begiining to suspect fusebox issue
