Unhappy engine power reduced light???

its not a check engine light its in the dic area with the tire pressure and instant gas milage it come up and says REDUCE ENGINE POWER then in my rpd my fuel pressure drops to 72 psi when im supossed to be running like 600 more at normal idle. the car hass noooooo power. onstar said im not getting any fuel to my fuel rail do to low voltage on the fuel pressure regulator solenoide......... so he said there is a loose wire. i asked him if it was my check engine light and he said noo that i have a check engine light do to not haveing a cat. soooo the wire is loose. reduce engine power comes on when it wants to or when ever its reading low voltage.

Hope this helps, no personal advice, but people around these parts can be very helpful. I just searched and found a few threads, sorry if they do not help.
