Find the terminal box on the right inner fender well and jumper it using an open paper clip ~ it that works reliably use your Fort relay to pass the key's current directly from the battery to the original solenoid trigger wire ~ that's the red one under the phillips screw .

Don't sweat using a screwdriver for testing, also open needle nose pliers, nickles and so on .

This is fiddly and it can be the NSS failing or the electrical portion of the key switch .

Most enthusiasts here like to keep it pristine and original but not always possible for everyone, the Ford solenoid is a common repair / fix for many systems .
