1997 GMC Suburban fuel system problems

FUEL SYSTEM, GASOLINE

SPRING OF 2008 WE REPLACED THE FUEL PUMP. THEN IN NOVEMBER 2008 THE FUEL PUMP FAILED AGAIN. THE MECHANIC SAID THEY WERE BOTH BRAND NEW FUEL PUMPS BUT HE WAS UNSURE OF WHY THEY BOTH FAILED TO WORK PROPERLY WHEN WE TOOK IT BACK IN MARCH 2009. 3 NEW FUEL PUMPS ALL WITHIN ONE YEAR SOUNDS LIKE A PROBLEM TO US. THE MECHANIC ALSO HAD TO REPLACE THE HARNESS. EACH TIME WHEN THE FUEL PUMP WENT OUT THE CAR JUST WOULDN'T START. IT WOULD DRIVE FINE AND THEN JUST NOT RESTART ONCE TURNED OFF.
