Flight crew on an MD80 performs a go around when nose gear showed unsafe. It was found that the hydraulic pumps were still in 'low' position, a missed item on the approach checklist. First officer noted distractions, one being an arrival change and subsequent reprogramming of the omega.

Narrative:
Location: 6 NM north dfw runway 17C. On final at dfw runway 17C the nose gear indicated unsafe. At 1000 ft AGL the captain directed a go around. Shortly after initiating the go around we noticed the hydraulic pumps in low. Placing them to high solved the problem and landing was normal. Not an excuse, but the descent was extraordinarily busy with a change to an unfamiliar arrival, reprogramming the omega and a similar call sign on frequency. Nevertheless we both missed this checklist item.

Narrative: LOCATION: 6 NM N DFW RWY 17C. ON FINAL AT DFW RWY 17C THE NOSE GEAR INDICATED UNSAFE. AT 1000 FT AGL THE CAPT DIRECTED A GAR. SHORTLY AFTER INITIATING THE GAR WE NOTICED THE HYD PUMPS IN LOW. PLACING THEM TO HIGH SOLVED THE PROB AND LNDG WAS NORMAL. NOT AN EXCUSE, BUT THE DSCNT WAS EXTRAORDINARILY BUSY WITH A CHANGE TO AN UNFAMILIAR ARR, REPROGRAMMING THE OMEGA AND A SIMILAR CALL SIGN ON FREQ. NEVERTHELESS WE BOTH MISSED THIS CHKLIST ITEM.
