Hello again.

Have you tested the fuel pressure recently? It might be possible you got a defective/weak pump. If you don't have access to a fuel pressure tester your local auto parts stores have a tool loaner program and will rent you one.Here is a tutorial showing what is involved:

I've attached below the fuel pressure specifications for your car as well as a wiring diagram.Hope this helps.
