My car is experiencing low fuel pressure, and I am trying to diagnose the issue, but I cannot find the fuel pressure regulator to do a certain test. Please help

Hello, it looks like the regulator is part of the fuel pump assembly, it's not regulated by intake vacuum, it's a built-in spring. Check to see if the fuel pressure holds after the key is off (bad check valve), if it doesn't hold fuel pressure, I block off the injectors to make sure pressure is not leaking down through any injectors. Also load testing the power and ground at the pump connector is necessary if you suspect a wiring or relay issue.
