Hello, I'm Danny.

I believe you have a weak/failing fuel pump or fuel regulator. Your readings are very low.The specifications for your vehicle is 375-395 Kpa. Here is a tutorial showing how to replace a fuel pump:

I've attached a picture below showing the fuel pump assembly.The assembly is mounted inside the fuel tank. Hope this helps and feel free to ask any questions if needed.Thanks for using 2CarPros.

The fuel pressure sensor at the rail always go bad. If the pressure sensor reads different it will try to adjust the fuel pressure where it will lower it down and cause problems.
