If battery voltage is not present, check ENG fuse and FUEL INJ fuse in engine compartment fuse block. Replace fuse(s) as necessary and check for cause of blown fuse. If fuses are okay, check main relay. See RELAYS under RELAYS & SOLENOIDS. If relay is okay, locate and repair open between main relay and PCM connector.
