We have just finish testing the system and there is power to the fuse and relay and both are functioning properly but there is no power in the wires to the fuel pump. Would you happen to know the routing of the wires after the distribution box?

Check and test the fuel inertia cut off switch

The inertia switch registers on the dash panel when the button is pushed up and the light shuts off when button is pushed back down.
