P0087 is a relatively common OBD II trouble code. This code indicates that there is an issue with getting enough fuel pressure to the fuel rails. It’s generic, which means that it has the same meaning for the Hyundai as it would any other vehicle.
This code is most common on vehicles that use a returnless fuel system. This means that the fuel pump adjusts the pressure going to the fuel rail based on the demands of the vehicle, therefore eliminating the need for a return line.
I would check and test the fuel pump relay and fuses and replace if needed also carry out a fuel pressure test check the inertia switch has not activated and popped up also you could check the supply voltage to the low pressure in tank fuel pump and replace if needed.

The fuses looked fined and relay was replaced, and when I had replaced the fuel pump it seemed fine it ran that same day and the following day was when I was having that issue, I will check the fuel pressure and not sure where the inertia switch would be located

Do you have a manual it will have the location in the manual but normally it can be under the engine bay normally by the top strut bolts top wheel arch area or in the boot luggage area or even in the glove box.
