An air carrier flight crew knowing that the high pressure bleed was inoperative, taxi-out with a bleed inoperative annunciation showing. However, when they apply full power and the duct pressure remains at zero they realize that both the normal and the high pressure valves were wired shut. B767-300ER.

Narrative:
#2 engine hi-stage bleed inoperative -- deactivated. When I started engine we had a bleed inoperative light. I thought it highly unlikely that the other bleed on same engine had failed. I assumed that when we got high power on the engine the bleed would operate. I could not put high power on due to snowy and slippery conditions as we taxied out. I told the first officer who was making the takeoff to go to takeoff power before releasing brakes. Due to slippery conditions he could not do this so we began takeoff at approximately 60 KTS. We still had bleed light on, anti-ice valve light on and zero duct pressure. I discontinued takeoff and returned to gate for repairs.

Title: AN ACR FLC KNOWING THAT THE HIGH PRESSURE BLEED WAS INOP, TAXI-OUT WITH A BLEED INOP ANNUNCIATION SHOWING. HOWEVER, WHEN THEY APPLY FULL PWR AND THE DUCT PRESSURE REMAINS AT ZERO THEY REALIZE THAT BOTH THE NORMAL AND THE HIGH PRESSURE VALVES WERE WIRED SHUT. B767-300ER.
Narrative: #2 ENG HI-STAGE BLEED INOP -- DEACTIVATED. WHEN I STARTED ENG WE HAD A BLEED INOP LIGHT. I THOUGHT IT HIGHLY UNLIKELY THAT THE OTHER BLEED ON SAME ENG HAD FAILED. I ASSUMED THAT WHEN WE GOT HIGH PWR ON THE ENG THE BLEED WOULD OPERATE. I COULD NOT PUT HIGH PWR ON DUE TO SNOWY AND SLIPPERY CONDITIONS AS WE TAXIED OUT. I TOLD THE FO WHO WAS MAKING THE TKOF TO GO TO TKOF PWR BEFORE RELEASING BRAKES. DUE TO SLIPPERY CONDITIONS HE COULD NOT DO THIS SO WE BEGAN TKOF AT APPROX 60 KTS. WE STILL HAD BLEED LIGHT ON, ANTI-ICE VALVE LIGHT ON AND ZERO DUCT PRESSURE. I DISCONTINUED TKOF AND RETURNED TO GATE FOR REPAIRS.
