You must have a short somewhere. Start by checking aroung the wires that are under the air intake hose that runs across the driver side of the motor. Sensor wires are close to heater plumbing and would short other systems also look for wires were o2 sensor connect to other wires. Most common is the o2 sensor wiring comes in contact with the exhaust and shorts out. Fuel pump is on same circuit as the o2 sensor.
