Hi guys

Done plenty searching on this. It’s great how many years you can go back on this forum! However, can’t find an answer to my problem.

Fuel pump doesn’t prime on ignition, nor does it kick in when the starter is turning.

Bridge the pins on the relay, or open the relay and manually operate the relay and the car fires and runs without issue.

Pump replaced
Fuel filter is new
Relay is new and a genuine Ford part

I can only think that whatever is telling the relay the ignition is on isn’t doing so as everything else is working? Could be wrong but I’m thinking this is the green and red wire in the centre of the relay on pin 1 however I’ve no idea where this goes to.

any advice much appreciated!
