1997 Chevrolet Silverado 2500

I OWN A 1997 SILVERADO 6.5 DIESEL ENGINE, W/279K MILES, TRUCK WAS RUNNING OK BUT THE LAST FEW MONTHS ENGINE STALLING AND STOP WITHOUT REASON, TOOK IT TO A REPAIR CENTER, DIAGNOSE WITH FUEL INJECTION PUMP FAILURE, DIESEL DEALER EXPLAINED THIS IS A WELL KNOWN DEFECT, FUEL INJECTION PUMP HAS AN ELECTRONIC COMPONENT (PMD) LOCATED ON THE SIDE OF THE PUMP WHEN ENGINE GETS HOT SENT FAILURE SIGNAL TO THE MAIN COMPUTER. CONTACTED GM CUSTOMER SERVICE TO VERIFIED THE ISSUE, ANSWERED THAT YES INDEED THEY AGREED ABOUT THE PROBLEM ALSO SAID THEY HAD 'CAMPAIGN' NOT A RECALL TO FIX THE PROBLEM BUT DIDN'T MAKE ANNOUNCEMENT TO PUBLIC. I ASKED FOR HELP TO FIX THE PROBLEM WAS TOLD THAT I RUN OUT OF OPTIONS THEY ONLY HONOR THIS PROBLEM FOR 10 YEARS OR 120K MILES? I WAS NOT AWARE AND NEVER RECEIVED A LETTER FROM GMC. THIS IS A ACCIDENT WAITING TO HAPPEN WITH TERRIBLE CONSEQUENCES, IF THE ENGINE STOPS OR STALL GOING DOWN THE HILL IN ANY URBAN OR RURAL AREA; PASSING ANOTHER CAR IN A BUSY HIGHWAY AND STALLING OR JUST THE ENGINE QUIT RUNNING. CROSSING A BUSY INTERSECTION WITH KIDS INSIDE AND NO POWER (HORRIBLE ACCIDENT WITH SERIOUS INJURIES AND CASUALTIES!!) I USUALLY AM TOWING A HORSE TRAILER ON BUSY HIGHWAY AND SUDDENLY STALL OR STOPPING IN FRONT OF A SEMI-TRAILER, CROSSING A RAIL ROAD AND STALLING IN THE MIDDLE WITH PEOPLE INSIDE A TRAIN COMING ITS WAY! THESE ARE A FEW CONSEQUENCES THIS FAILURE CAN CREATE, WHILE THIS IS A FACTORY FAILURE AND POOR DESIGN. I HAD REPLACED THE (PMD) AND AFTER SPENDING OVER $2500.00 STILL HAVE THE SAME PROBLEM. AT THE PRESENT TIME I AM NOT DRIVING THE TRUCK MUCH UNTIL I CAN GET THIS RESOLVED FROM YOUR AGENCY TO SEE THE RESULTS OF YOUR INVESTIGATION. IS THIS JUST ANOTHER WAY OF SOAKING THE PUBLIC WITH REPAIR BILLS EVERY SINGLE YEAR. I NOW HAVE HAD THE PMD REPLACED ONE YEAR AFTER THE FIRST INJECTION PUMP SERVICE AND AGAIN ONE MORE YEAR LATER THIS PROBLEM HAS NOW RETURNED AND ANOTHER $2500 IS REQUIRED TO FIX IT YET AGAIN. WHAT ARE YOU GOING TO DO ABOUT IT? *TR
