Hi my 4/4 Zetec failed to start. Checked pump no feed bridged out relay pump runs.
The yellow black wire which needs to be earthed to operate the relay is linked to the inertia switch then disappears in to the loom under dash.
I can’t find any yellow and back wires.
Any one know where it goes befor it earths out
I have cut wire and grounded at relay runs fine.
