I got a 2004 Nissan Sentra and I just got the loaner fuel pressure tester from Autozone. Looking to test the fuel pressure on my car. Looking to see if someone has tested the fuel pressure on a car like mine and exactly how do things get set up to test it because this car does not have a test port?

You need a universal fuel pressure gauge set.

No port means you need to disconnect the fuel inlet and tee in with one of the myriad of test fittings shown in Tester’s picture.

I have the test set that @Tester showed and tucked into a large opening on the lower half where the instructions and replacement O-rings were stored are now 6 or so contraptions that I made to enable connecting to various vehicles that weren’t included in the set. As best I can recall foreign throttle body systems were the most common cause for cobbling up connections.

Edit: I’ll add that my test set dates back to the early 90s and was from Snap-On but it looked very similar to @Tester 's picture.
