    did you clear the code? It'll take a few ignition cycles for it to clear on it's own. Do you have anyway to log the car to look at fuel trims?

    You should clear the code and see if it comes back. it will turn off on its own eventually but maybe not right away.
    Fuel pressure should be between 55 and 60 psi.

    Can u clear it with an obd 2 tester? And no I have no way of checking fuel trims on my own. Thanks for the info on the fuel pressure, if the code won't clear ill check that to see if maybe my pump is on the way out

    well hopefully there is no need, light went out after about 5 mins after i fired it up for the drive home from work. thanks to all who helped me on this I'll let you know if the light returns ( seems how before it was going on and off ).
