Do you have power at the fuel pump relay? Do you get power at the gray wire at the fuel pump relay? If you have power at the gray wire at the relay when cranking then check the wire for a break going to the tank.

We do not get power to the orange wire on the relay. We put power to the orange wire and it starts. We need to know why it will not get power the right way.

Do you have power at the fuse? If yes then the wire is broken from the fuse to the relay. If no power then check the fusible links at the starter motor of at the firewall. The fusible links are the soft orange wires that connect to the red power wires. Lightly pull on the red wire and if the fusible link is blown then the orange rubbery wire will beak in two.
