Check the brown wire from the CTS for shorts,
It runs from CTS to plug "A" terminal #38.
peel back all the insulation from the harness and eyeball all of it.
Oh and thank you for all the correct information concerning vehicle/engine type.
Usually we just get "my Vauxhall won't work"
And we have to guess engine/fuel type even age!!
