Max's suggestion about swapping relays is a good idea.
Before the swap, a gentle tap on the fuel relay with the handle of a screwdriver (mini mallet) may bounce the contacts to allow the fuel pump to activate.
If that works, go ahead and replace the relay.

I do not know about the 2013, but the 2014 standard has a 4 pin connector (to accommodate the fuel gauge).
Yellow/red changes to brown at the connector, then goes to the fuel pump relay for power.
Black/white changes to green/black at the connector, then goes to ground.
If the ground is clean, as Popgun already suggested, the pump can be tested by powering the yellow/red wire, while grounding the black/white.
I am sure Popgun will advise if the 2013 schematic is different.
2013 fuel pump assy has a flat, 3 pin connector, versus square 4 pin for 2014
AND I bet 1x U$100 ca$h that there is NO real corrosion
