## Discrepancy

CAPTAIN REPORTED THAT DURING TAXI, STARTED ENGINE 2 AND EVERYTHING APPEARED NORMAL, BUT AFTER ADDING POWER ABOVE IDLE, RECEIVED 'ENG 2 FAIL' MESSAGE. ATTEMPTED CROSS BLEED HUNG START.  APU BLEED START ALSO FAILED.  MAINTENANCE REMOVED AND REPLACED NR 2 FUEL METERING UNIT AND LP/HP FUEL PUMP.  AFTER REVIEW OF TEARDOWN REPORTS THE FMU WAS THE ROOT CAUSE WITH A SERVO VLV LEAKING.
