car runs rich, -7, low feul pressure, hard time accelerating especially on hills-small and big ones, hard start, rough idle.

What is the -7? Also, if the fuel pressure is low, that is a concern. Have you checked the regulator? Have you checked to see if the fuel filter is plugged? If everything checks out, then chances are the pump is weak.

Dealership has my car overnight, they said so far they can't find anything wrong. They checked the fuel pump and told me its good. I can't remember what the -7 is, a friend of mine ran a scanner on my car is he pushed on the gas pedal and my car showed that number. All I know its representing my car running to rich. I've been dealing with this since Feb. 2013 with intermittent failing when I put the car in park.

I wonder if the -7 is what the temp sensor is telling the computer the coolant temp is. If that is the case, the computer will compensate for the cold temp by making the fuel mixture richer. That could be the entire problem. Can you ask your friend if that is what it was?
