1994 Chevrolet C/K Pickups

FAILURE OF FUEL INJECTION PUMP OCCURED ON 3 DIFFERENT OCCASIONS . THE FIRST FAILURE OCCURED ON AUGUST OF 1997 WITH 28800 MILES WHILE STILL UNDER WARRANTY. FUEL INJECTION PUMP WAS REPLACED AT JAY CHEVROLET IN HIGHLAND , MICHIGAN. THE SECOND FAILURE TOOK PLACE IN JULY OF 1999 WITH APPROX. 45000 MILES REPAIR DONE AT CHAMPION CHEVROLET HOWELL, MI . THREE MONTHS AFTER SECOND REPAIR, MAJOR ENGINE DAMAGE OCCURED AS A RESULT OF DEFECTIVE FUEL INJECTOR, CAUSING LOSS OF STEERING AND BRAKE SYSTEMS & PUTTING DRIVER AND ALL OTHER ROAD TRAFFIC IN DANGER. THIS TRUCK IS USED IN A SEASONAL BUSINESS WHICH RUNS FROM APRIL - NOV. BECAUSE WE USE THE VEHICLE ONLY 7 MONTHS OF THE YEAR, WE HAVE GONE OVER THE 5 YEAR WARRANTY BUT ARE WAY UNDER THE 100,000 MILE WARRANTY . AUTHORIZED CHEVROLET SERVICE TECHNICIANS ACKNOWLEDGE MANY PROBLEMS WITH FAULTY FUEL INJECTION PUMPS ON THE DIESEL ENGINES, YET THE MANUFACTURER ACCEPTS NO RESPONSIBILITY TO REPAIR AND OR REPLACE DAMAGES CAUSED FROM DEFECTIVE PARTS INSTALLED BY THE MANUFACTURER . THIS IS A POTENTIALLY SERIOUS SAFETY DEFECT AND SHOULD BE GIVEN IMMEDIATE ATTENTION. I HAVE MADE SEVERAL ATTEMPS WHILE STILL UNDER WARRANTY TO HAVE ALL PROBLEMS WITH FUEL INJECTION SYSTEMS TO BE REPAIRED SO THAT WE CAN GET REASONABLE USE FROM THIS VEHICLE. THERE IS NO ONE THAT CAN SAY 49,000 MILES ON A DIESEL ENGINE IS REASONABLE LIFE EXPECTANCY. I WOULD APPRECIATE ANY HELP OR SUGGESTIONS YOU MAY HAVE SO THAT WE CAN RESOLVE THESE PROBLEMS ONCE AND FORALL.
