Your Valet cancel switch is set.


Open your glovebox and you will see a pushbutton on the the left side, if memory serves. When this button is set, the power button will be disabled, but the key fob button will still work.
This is for when you Valet your car, you push the cancel button in the glovebox, lock the glovebox, then give the Valet your Valet key, which will not open the trunk or the glovebox. Voila, no Valet rummaging through your trunk :)

Often full gloveboxes will be the cause of the button getting pushed accidentally.

under the hood to find the fuse/relay for fuel pump

Check to see if there is a fuse if not check the trunk switch that turns on the light.

Loosen the two screws that hold the metal latch to the dash board and move it out a bit. May take a couple of times to get it right.

Check the fuel filter, fuel pressure and fuel flow . Check the fuel pressure regulator, the rail pressure should rise when the gas pedal is jabbed , check the vacuum hose to the regulator is ok.
