## Discrepancy

THE CREW REPORTED THE APU TEMP WENT AMBER DURING ENGINE START AND A STRONG ODOR OF FUEL IN THE COCKPIT.  MAINTENANCE FOUND THE RT AIR CONDITIONING PACK DID NOT SHUT OFF DURING ENGINE START.  THEY REPLACED RELAY K0320 AND THE APU OPERATED PROPERLY WITH NO ODOR OR TEMP SPIKE DURING ENGINE START.
