The fuel pump relay is under hood, passenger side, front side of strut tower, mounted in relay panel on radiator support .
I could not find the relay for the injectors, I think the computer is responsable to activate the injectors.
the refuel pump relay is responsable to activate the fuel pump;
if there is problem with the fuel pump, check or replace the relay
if the relay is good, check or replace the fuel pump inline fuse (15 A)
if the fuse is good, then the last thing is the fusible link.

sending you the diagram
