Have you tested relays and checked fuses first?
Here are two guides and a video to help us see whats going on.
You can remove the relay and take it to any auto parts store i.e Napa, Autozone, Advanced auto parts, to test the relay for you. Or touch the relay with it plugged into the connector and have someone turn your car on (not crank it) you should feel the relay click. If it doesn't click, then the relay is not coming on. Check power to relay. There is one wire that should be consistently hot, usually an orange or red color. If you unplug the relay and use a multimeter to check the terminals on the relay connector, there should be one terminal that gets voltage with the car off. If power is getting to relay but relay is not clicking, replace relay.
If still need to test fuel pump wiring, check voltage of the GREY wire.
Please run down these guides and report back.
