Car sometimes delays when I start it. The diagnostic test says it is the fuel pressure rail sensor. That's why I'm wondering if the fuel injector is the same thing or something different than the fuel pressure sensor?
Is the fuel pressure rail sensor the same as the fuel injector? on 2005 Ford Focus

It's called a FUEL RAIL PRESSURE SENSOR and that is exactly what it's purpose is! It senses the fuel pressure in the fuel rail that feeds the injectors. It then sends an electrical signal to the computer so it can adjust this pressure as needed. It is not the same thing as an injector, it just regulates the fuel pressure going to the injectors.
