I changed the fuel pump in my wife's car and it's from a Kia 2013 Sonata it fits connects in with every port but I'm still not getting power to fuel pump and in this car, I have a fuel pump fuse. No fuel pump relay that I've researched and found so what could be the issue when even the fuse is good.

Okay, so you are not seeing power on pin 4 in the pump connector. I would test the relays output in the EMS box. Should be able to hear it click when the key is turned.
Replacement is simple, just unplug the old and plug in the new.

Yes, I hear the click when I try and start it but the problem is that my EMS box only shows me the fuel pump fuse, and that's perfectly okay. So, I've tried to google and YouTube everyday called Hyundai and nobody seems to know what relay it is. Can you please help? I have 2013 Hyundai Santa Fe Sport 2.0l turbo with two pumps installed for high injection pump and fuel pump. Most of the relays on this car are multifunctional so I don't Know which one to pull.

Does your EMS box look like the last image above? 18 is the relay, it might be inside the box though. The second diagram sort of hints at that with the dotted lines and solids. A way to verify it as the relay would be to find the pink power feed and use a 20A fused jumper to jump power to it. If the car now starts and runs you have a bad relay. If it's built in, you could always add an external relay. Or take a close look at the box and see if the relay is on the back side of it. If possible, take a picture of it and load it on here and I'll see if the info is correct.
