Ford f-150 truck

I have a ford f-150 yesterday while driving it just shut off, I hot wired the fuel pumps to check them and they’re fine, I replaced the fuel relay, truck still won’t start, relay is getting 12 volts going into it but only 6 volts comming out, pumps need 12 volts to work.

Even with pumps dissconnected, 6 volts comming out of relay

Do you know whats wrong?
