Check the main fuses in the green box at the battery and the fusible links in the black box beside it. Power goes from battery+ to the fuse, to a fusible link, to the key switch, to the MPI control relay mounted in the front passenger kick space and on to the pump. The MPI control relay is triggered by the ECU.
