-4 F sounds cold.
There is a fuse, it is under a cover on the driver's side lower dash. This is the layout:
So check the 3rd fuse and make sure it has not blown. A bit of a long shot but at least it is easy to check.
Do you have a multimeter? If so, use that the check the fuse, and if not....take another car to the shop and buy one
If the fuse is OK the best thing is to get straight into the fuel pump wiring. Open the boot remove the boot floor (a couple of 10mm nuts from memory) and you will see the fuel tank cover. Remove that too, and unplug the plug with 2 wires (fuel pump wiring, the other plug is the fuel level sender and warning light). Turn the ignition on and immediately (ie within 2-4seconds) check for 12v between the 2 terminals of the plug. If there is power there the fuel pump is not working (no fuel? pump dead? fuel line froze, I think the last one is a joke?). If there is no power there you have an issue in the ECU, relay, wiring or power supply.
But before all that, do you have an immobiliser that may have failed? or is it out of fuel? why do you think there is no fuel pressure, do you have a gauge?
