2003 GMC Sierra 2500 Fuel system Problems

HAD INJECTORS REPLACED UNDER WARRANTY AT 50000 MILES AFTER NOTICING EXCESS EXHAUST SMOKE ON STARTUP AND ALSO POWER STEERING HOSES WERE LEAKING, AGAIN AT 105000 MILES THEY TOTALLY FAILED AS I WAS BRINGING MY WIFE HOME FROM HOSPITAL ON I-15 IN CA. UP CAJON PASS AND HAD TO BE TOWED TO DEALER, BUT GM DEALER WOULD NOT COVER INJECTORS UNDER WARRANTY AS TRUCK WAS11 YEARS OLD AND THEIR COVERAGE WAS FOR 7 YEARS ONLY, NOW AGAIN HAD TO HAVE THEM REPLACED AT 147000 MILES BECAUSE OF EXCESSIVE SMOKE ON STARTUP. THIS TIME I WENT TO AN INDEPENDENT SHOP AS THEY WERE $1000 CHEAPER AND STATED THESE UPGRADED INJECTORS SHOULD LAST 150000 MILES NOT 50000. HAD TO HAVE POWER STEERING HOSES REPLACED AGAIN ALSO ALONG WITH POWER BRAKE SERVO BECAUSE THEY WERE LEAKING AGAIN AT 157000 MILES. I HAVE ALL OF THIS DOCUMENTED IN WRITING BY SERVICE DEPTS.

(ELECTRICAL) AS AN ONGOING ISSUE, THE DASHBOARD GAUGES/INDICATORS (I.E. TACH, SPEEDOMETER, ETC..) WILL SOMETIMES NOT REGISTER UNTIL SEVERAL MINUTES AFTER THE VEHICLE HAS BEEN RUNNING (THIS COULD BE FOR UP TO MILES) IT HAS NOT AFFECTED VEHICLE PERFORMANCE TO DATE. (FUEL/PROPULSION SYSTEM) I HAVE BEGUN HAVING ISSUES WHERE IT GOES INTO "REDUCED ENGINE POWER". FURTHER DIAGNOSTIC ATTEMPTS HAVE LED ME TO BELIEVE THAT IT IS DUE TO A FAULTY THROTTLE POSITION SENSOR (PART OF THE THROTTLE BODY), TAC MODULE, OR APP ASSEMBLY (ACCELERATOR PEDAL). MOST LIKELY CAUSE MAY BE DUE TO THE THROTTLE POSITION SENSOR, AS THIS ISSUE HAS HAPPENED WHEN THE VEHICLE IS ON "CRUISE CONTROL". HOWEVER, DUE TO THE INFERIOR DESIGN OF THE THROTTLE BODY UNIT ITSELF, THE MANUFACTURE HAS MADE IT DIFFICULT OR IF DESIGNED TO BE IMPOSSIBLE TO REPLACE JUST THE TPS, BY RIVETING THE TPS TO THE THROTTLE BODY, AND MAY HAVE TO REPLACE THE WHOLE THROTTLE BODY. I AM HAVING THE VEHICLE SERVICED FOR A COMPLETE DIAGNOSTIC AND REPAIR, AND WILL ELABORATE FURTHER UPON SUCCESSFUL REPAIR IF DESIRED. *TR

WHILE DRIVING, LARGE AMOUNT OF SMOKE CAME OUT. TOOK IT TO GM DEALER WHO SAID THAT IT THE FUEL INJECTORS WERE LEAKING. LOOKED ONLINE AND NOTICED HUNDREDS OF REPORTS OF THE SAME ACTION. GMC APPARENTLY DID AN EXTENDED WARRANTY FOR THE ISSUE, BUT ONLY COVERED IT FOR 7 YEARS FROM TIME OF PURCHASE AND UP TO 200,000 MILES. TALKED TO LOCAL DEALER WHO DENIED THE SERVICE AND GM WONT REPLACE THE FUEL INJECTORS. *TR

2003 GMC SIERRA 2500HD WITH DURAMAX DIESEL STARTED RUNNING ROUGH BECAUSE OF LOW FUEL. LOW FUEL WARNING LIGHT DID NOT COME ON. PUT 4 GALLONS OF FUEL IN VEHICLE AND SCHEDULED APPOINTMENT FOR 08/02/05 WITH GUNN CHEVROLET SERVICE, SAN ANTONIO TEXAS. MECHANIC COULD NOT FIND ANY TROUBLE CODE. WAS TOLD BY SERVICE ADVISER BRIAN LECOURSE THAT THERE IS NO CALIBRATION OR STANDARD FOR LOW FUEL WARNING LIGHT TO COME ON AND IT MAY COME ON WHEN VEHICLE IS RUNNING OUT OF FUEL. I FILLED UP THE VEHICLE WITH 25.2 GALLONS OF FUEL FOR A 26 GALLON TANK. THE LOW FUEL WARNING LIGHT STILL WAS NOT ON AND THE DRIVER INFORMATION SYSTEM SHOWED 36 MILES LEFT TO TRAVEL. I WENT BACK TO GUNN CHEVROLET AND WAS TOLD THAT THE PROBLEM COULD NOT BE FIXED. GENERAL MANAGER CHARLEY O'DANIEL SAID THAT THE PEOPLE THAT DESIGN THE VEHICLES ARE SMARTER THAN THE PEOPLE THAT FIX THEM AND THAT TECH LINE STATED THERE WAS NOTHING THAT COULD BE DONE WITH THIS PROBLEM. CHARLEY O'DANIEL SAID NOT TO LET THE VEHICLE GET BELOW 1/4 FULL AS DAMAGE COULD OCCUR TO THE ENGINE FUEL PUMP. *JB
