2000 GMC YUKON XL Fuel System, Gasoline Problems

FUEL PUMP IS WHISTLING AND FUEL LEAK IS APPARENT WHEN PARKED OVERNIGHT IN GARAGE. ALREADY REPLACED ONE PUMP AT 96,000 MILES. ALREADY HAD SERVICE ON THE MELTED WIRES 2 YEARS AGO. CAN GM PROVIDE THE COST OF THE GM BRAND FUEL PUMP SO IT CAN BE REPLACED? *JB

MY GMC YUKON XL HAS BRAKING AND FUEL SYSTEM PROBLEMS, I HAVE HAD 1 ACCIDENT BECAUSE OF THE YUKONS BRAKES DEACTIVATING WHILE HITTING A SMALL BUMP ON THE STREET WHILE TRYING TO AVOID THE ACCIDENT. I HAVE CONTACTED GMC AND ALL THEY SAID IS THEY WOULD OFFER ME A 1,000 REBATE ON THE NEXT PURCHASE OF ANOTHER VEHICLE, ALTHOUGH THEY ADVERTISED THIS DEFECTIVE PRODUCT ON ("CNN") ALONG WITH THE OTHER DEFECTS. THERE HAS BEEN OTHER HIDDEN RECALLS ON THIS VEHICLE AND THE MANUFACTURER DID NOT PROPERLY TELL OR NOTIFY ME. *JB

OUR GAS GAUGE ON OUR 2000 GMC YUKON COMPLETELY QUIT WORKING. TOOK IT IN THINKING IT WAS AN ELECTRICAL PROBLEM AND FOUND OUT THE FUEL PUMP WAS BROKEN. THE PROBLEM THAT COST US A LOT OF MONEY WAS THAT THE FUEL PUMP IS LOCATED INSIDE THE GAS TANK AND THEY HAD TO REPLACE THE WHOLE GAS TANK TO FIX THE PROBLEM. FIRST, WHY WOULD THIS HAPPEN ON A CAR THIS NEW WITH ONLY AROUND 50,000 MILES AND SECOND, WHY PUT THE FUEL PUMP INSIDE THE GAS TANK SO THAT IT IS SO EXPENSIVE TO FIX? *JB

THE VEHICLE WOULD STALL WITHOUT WARNING. TYPICALLY, THE STALL WOULD OCCUR WHILE THE VEHICLE WAS COLD, OR DURING TURNS AT INTERSECTIONS-GOING FROM ONE ROADWAY TO ANOTHER.*AK DEALERS RESPONSE HAS BEEN A "DIRTY THROTTLE BODY," CODE J5485

NOTICED ON SEVERAL OCCASIONS THAT VEHICLE SEEMED TO BE LEAKING FUEL WHEN PARKED AND TURNED OFF. MOST RECENT CASE OCCURRED SHORTLY AFTER REFUELING. DEALER DIAGNOSED AS A "CRACKED FUEL SENDING UNIT". APPARENTLY THIS ALLOWS FUEL TO BE SPEWED OUT OF THE TANK WHEN PARKED. DEALER INDICATED THAT IT WASN'T COVERED BY WARRANTY DUE TO MILEAGE. CO-WORKER DISCUSSED ALMOST IDENTICAL PROBLEM WITH HIS YUKON XL (EXCEPT HIS SPEWED MORE FUEL INTO HIS GARAGE AND NEED TO BE CLEANED-UP BY HAZMAT TEAM). THIS APPEARS TO BE MORE THAN A RANDOM OCCURRENCE OF A PROBLEM THAT HAS SIGNIFICANT SAFETY AND ENVIRONMENTAL IMPLICATIONS. I BELIEVE FURTHER INVESTIGATION (BY THE NHTSA AND GENERAL MOTORS) IS WARRANTED. *NLM

THE VEHICLE STALLED. THE DEALER DIAGNOSED THE PROBLEM AS BAD BARE WIRES INSIDE OF FUEL PUMP. THE WIRES SHORTED WHICH CAUSED VEHICLE TO STALL. *JB

I OWN A 2000 GMC YUKON XL. OVER THE PAST FEW MONTHS, I HAVE HAD A PROBLEM WITH THE VEHICLE CONTINUALLY BLOWING A FUSE (ECM B FUSE). UPON MY OWN RESEARCH INTO THE CIRCUITRY, I DETERMINED THE LIKELY PROBLEM WAS THE FUEL PUMP. I REPLACED THE FUEL PUMP AND UPON REMOVING AND INSPECTING THE OLD COMPONENT, I DISCOVERED THE HOT WIRE (GRAY WIRE) WHICH OPERATES THE PUMP MOTOR HAD BEEN HOT ENOUGH TO MELT THE INSULATION OFF THE WIRE. MOREOVER, THIS HOT WIRE HAD MELTED INTO ONE OF THE WIRES OF THE FUEL LEVEL SENDING UNIT, WHICH IS A GROUND CIRCUIT. THE PROBLEM I WOULD LIKE TO BRING TO LIGHT HERE IS THAT THE FUEL PUMP UNIT IS INSIDE THE FUEL TANK. WHEN THIS HOT WIRE CAME INTO CONTACT WITH THE OTHER WIRE, I ASSUME THERE WAS A SPARK, OR THE POTENTIAL FOR ONE. WHY DIDN'T MY VEHICLE EXPLODE? I KNOW THERE ARE THOUSANDS OF THESE VEHICLES ON THE ROAD, BUT I HAVE NOT HEARD OF ANY SUCH EXPLOSIONS. I DO KNOW OF ANOTHER GM VEHICLE THAT HAD THE SAME PROBLEM OF EXPOSED WIRES IN THE FUEL TANK. PLEASE ADVISE ME OF THE DANGER LEVEL SHOULD THIS HAPPEN AGAIN. THANK YOU. *NLM
