I HAVE A 1998 GMC K3500 PICK-UP TRUCK WITH A 6.5 TURBO DIESEL HO ENGINE. WHILE DRIVING ALONG THE ENGINE CONTINUOUSLY CUTS OFF AS IF IT IS NOT GETTING FUEL EVEN THOUGH THE TANK IS FULL OF FUEL. TOOK TRUCK TO DEALER TO HAVE PROBLEM CORRECTED. DEALER INFORMED ME THAT FUEL IN TANK WAS BIO-DIESEL AND MY TRUCK WOULD NOT BURN BIO-DIESEL. THEY INFORMED ME MY TANK NEEDED TO BE REMOVED AND CLEANED ALONG WITH THE REST OF THE FUEL SYSTEM. THEY REMOVED TANK/CLEANED SYSTEM - COST $691.78, AND ADDED NEW FUEL. I PICKED UP THE VEHICLE, TRAVELED LESS THAN .25 MILES AND SAME PROBLEM RECURRED. RETURNED VEHICLE TO DEALER, THIS TIME THEY INFORMED ME I NEEDED TO HAVE THE INJECTOR PUMP REPLACED - $1,363.00. I AGREED. THEY REPLACED THE INJECTOR PUMP AND REMOVED AND CLEANED FUEL TANK AGAIN. AFTER PICKING UP THE VEHICLE AFTER THIS REPAIR, THE FUEL LINES FROM ENGINE TO FUEL TANK BEGAN TO LEAKING. THIS COST ME AN ADDITIONAL $123.72 WHICH I PAID TO THE DEALERSHIP AND HAD TO FINALLY STRAIGHTEN OU
