Mandy, you could just have a bad main relay. The main relay should be under the driver's side of the dash, by the brake pedal. The Blue/White wire powers the fuel pump. When the key is turned on, the Engine Control Module will ground the Green/Yellow wire for 2 seconds so the fuel pump will operate. If there is no or low voltage on the Blue/White wire, then verify that the White/Black wire has good battery voltage. Also, make sure to check the check the Black wire for a good ground. Check fuse number 9 in the under-the-dash fuse box.
