2001 GMC Sierra Fuel system Problems

WHEN MY ISSUES STARTED, I WOULD FILL MY GAS TANK AND THE GAS GAUGE WOULD PLUMMET TO EMPTY. WHILE DRIVING, IT WOULD GO TO FULL, BACK TO EMPTY OR BE ANYWHERE IN BETWEEN. AT THAT TIME, THERE NO NO MECHANICAL ISSUES, JUST THE ANNOYING FACT THAT YOU HAD NO IDEA HOW MUCH FUEL YOU ACTUALLY HAD. THIS WENT ON UNTIL THIS SPRING, WHEN I HAD THE FIRST POTENTIALLY DANGEROUS INCIDENT. I WAS DRIVING DOWN A COUNTY HIGHWAY AT APPROXIMATELY THE SPEED LIMIT AND THE TRUCK'S ENGINE JUST SHUT OFF. NO POWER STEERING, NOTHING. IT HAPPENED JUST AS I WAS COMING TO A STOP SIGN THANKFULLY. I WAS ABOUT 50 MILES FROM HOME AND WAS ABLE TO CALL A FRIEND THAT MANAGES THE COLLISION CENTER OF A LOCAL CAR DEALERSHIP TO SEE ABOUT GETTING A TOW OR HIS OPINION AS TO WHAT WAS WRONG. AFTER ABOUT TEN MINUTES AND AFTER NUMEROUS ATTEMPTS, IT RESTARTED. I TALKED TO SEVERAL MECHANICS AND GOT THE SAME ANSWER FROM ALL OF THEM: THE FUEL PUMP AND SENDING UNIT FAIL IN GMC TRUCKS AROUND THE MILEAGE, 95,000 MILES, THAT I CURRENTLY HAVE ON THE TRUCK. THE GAS GAUGE IS STILL ERRATIC, I HAVE HAD TWO EPISODES OF THE VEHICLE STALLING AND NOW THE SERVICE ENGINE SOON LIGHT IS COMING ON AND WHEN IT IS PUT ON AN ANALYZER IT SAYS EMISSIONS, BUT THERE IS NOTHING WRONG WITH THE EMISSIONS SYSTEM. I HAVE ALSO TALKED TO OWNERS WHO HAVE HAD THEIRS REPLACED AND EVERYONE SAYS TO GET A FACTORY MADE PUMP BECAUSE THE CHEAP AFTERMARKETS BREAK DOWN EVEN QUICKER. I GOOGLED THE INFORMATION AND THE PROBLEM APPEARS TO BE WIDESPREAD. *TR

FRONT BRAKE LINE FAILED. COMPLETELY RUSTED, IT BLEW OUT INSIDE ONE THE CLIPS THAT HOLD IT IN PLACE. HORRIBLE DESIGN. TRUCK IS SITTING IN MY DRIVEWAY BECAUSE I CANNOT AFFORD TO REPAIR BRAKES. ESTIMATE WAS OVER 1500, JUST TO REPLACE THE LINES, WITH COATED STEEL, NOT STAINLESS. FUEL LINES ARE ALL RUSTED AS WELL. ALL NEED REPLACEMENT. *TR

BACKED OUT OF DRIVEWAY AND BRAKE PEDAL FELT SOFT. GOT TO END OF STREET AND SUSPECTING A PROBLEM BEGAN SLOWING EARLY. BRAKE PEDAL WENT TO THE FLOOR WITH VERY LITTLE PRESSURE AND VERY LITTLE STOPPING POWER. WENT BACK TO HOUSE AND FOUND A LARGE PUDDLE OF BRAKE FLUID WHERE THE TRUCK HAD BEEN SITTING. OPENED THE HOOD TO LOOK AT BRAKE RESERVOIR AND FOUND IT EMPTY BUT ALSO REALIZED ALL HARD BRAKE LINES IN VIEW WERE HEAVILY CORRODED AND CRUSTED. LEAK WAS FROM BURST HARD LINE BELOW DRIVER. ALL HARD LINES ARE HEAVILY CRUSTED AND CORRODED NEAR THE POINT OF FAILURE IF NOT ALREADY FAILED. SOME FUEL LINES ALSO CORRODED. *TR

STATE INSPECTION, FAILED DUE TO ROTTED FUEL FILLER NECK. WAS TOLD FOR AWHILE IT WAS DUE TO GAS CAP, REPLACED THAT, LIGHT WOULD GO ON AND OFF. WHEN IT WOULD NO LONGER GO OFF TOOK BACK TO DEALERS. DEALERSHIP REPLACED FUEL FILLER NECK, ALONG WITH VALVE/SENSOR AT A COST OF OVER $500. GM WILL NOT HELP AS THEY CLAIM IT WAS DUE TO "ENVIRONMENTAL FACTORS" (WE LIVE IN MA). ALSO, PARKING BRAKE BACKING PLATES RUSTED OUT, E-BRAKE CABLES FROZEN, HAD TO REPLACE THOSE AT ANOTHER $850. OLD PARTS NOT AVAILABLE, DEALER REPAIRED. *TR

FUEL GAUGE HAS BEEN MALFUNCTIONING FOR SEVERAL MONTHS NOW - SOMETIMES WORKS PROPERLY, BUT OTHER TIMES READS EMPTY WHEN TANK IS FULL, READS MORE FUEL THAN IN TANK, ETC. I HAVE SEVERAL FRIENDS WHO HAVE THIS GENERATION OF GM FULL-SIZE TRUCK (GMC SIERRA, CHEVY SILVERADO, GMC YUKON, CHEVY TAHOE - GMT800 SERIES), AND MOST OF THEM HAVE THE SAME PROBLEM. I AM TOLD THAT THE ISSUE IS WITH THE FUEL SENDING UNIT. *JB

FUEL GAUGE HAS NEVER WORKED PROPERLY( JUMPS FROM 1/2 TANK TO EMPTY) TODAY I WAS DRIVE ON ! 40 EAST AT THE POSTED SPEED OF 75 MPH WITH 1/2 TANK OF FUEL AND THE VEHICLE JUST SHUT DOWN, I DID GET SAFLEY TO THE SHOULDER, TO FIND I WAS OUT OF FUEL ...I T READ 1/2 TANK PREVIOUSLY I HAD HEARD OF THIS HAPPENING TO OTHER GMC OWNERS IN THIS AREA BUT IT WAS THEIR FUEL PUMPS. THE DEALER SAYS IT IS THE LOCAL REFINERY'S FALT FOR ADDITVIES IN THE FUEL .. AND THIS IS THE ONLY AREA WHERE THE FUEL SYSTEM IS BEING AFFECTED. MY EMPLOYEER HAD 2 FUEL PUMPS PUT IN HER NEW GMC YUKON IN 6 MONTHS, AT HER EXPENSE. I DO NOT WANT TO PAY FOR DEFECTIVE PARTS OR AN VEHICLE THAT IS UNSAFE FOR THE INTERSATE.

AFTER FUEL PUMP WAS REPLACED, THE VEHICLE WOULDN'T START. *PH WHILE THE VEHICLE WAS UNDER WARRANTY, IT WOULD NOT START. THE FUEL PUMP WAS CHANGED BUT NOT THE CONNECTOR. THE PROBLEM RESURFACED AND QUIT RUNNING NUMEROUS TIMES. THE SERVICE DEALER STATED THAT THE FUEL CAP WAS NOT TIGHT ENOUGH WHICH CAUSED THIS PROBLEM. (THE CAP WAS TIGHTENED) THE VEHICLE STOPPED RUNNING WHILE AT A TRAFFIC LIGHT MORE THAN ONCE. THE CONSUMER HAD TAKEN THE VEHICLE TO THE DEALER AND HAD TO PAY FOR REPAIRS BECAUSE THE VEHICLE WAS THEN OUT OF WARRANTY. SEVERAL WEEKS LATER THE PROBLEM RECURRED AND THE SERVICE DEALER FOUND NO GAS PRESSURE AND REPLACED THE PUMP. THE VEHICLE STOPPED AGAIN WHILE THE CONSUMER WAS MAKING A LEFT TURN. THE CONSUMER HAD TAKEN UPON HIMSELF TO GO UNDER THE VEHICLE AND WIGGLED THE WIRING HARNESS WHICH STARTED THE VEHICLE. THE SERVICE DEALER CHANGED THE FUEL PUMP CONNECTOR HARNESS. (THE CONNECTOR WAS BURNED AND PITTED) *SC *JB

WHEN THE AIR CONDITIONER (A/C) IS USED IT TAKES AT LEAST EIGHT MINUTES FOR THE COOL AIR TO FLOW. THERE IS A FOUL ODOR COMING FROM THE VENTS THAT SMELLS LIKE ROTTEN EGGS. ALSO, CONSUMER IS CONCERNED WITH THE SOUND OF THE ENGINE. ALTHOUGH THE VEHICLE IS EQUIPPED WITH A GAS ENGINE, IT SOUNDS LIKE A DIESEL ENGINE. THERE IS A IRRITATING NOISE THAT OCCURS INTERMITTENTLY AT ANY SPEED. THE DEALER CLAIMS THAT THE NOISE IS NORMAL. *AK ENGINE BURNS 3 QTS. OF OIL EVERY 3000 MILES AND THE FUEL GAUGE ISN'T ACCURATE. *PH *NLM
