1996 GMC SUBURBAN Fuel System, Gasoline Problems

DT*: THE CONTACT STATED WHILE DRIVING VARIOUS SPEEDS ON THE HIGHWAY, THE ENGINE STALLED WITHOUT WARNING. AFTER STALLING, THE VEHICLE WAS NOT EASILY RESTARTED. THE VEHICLE WAS INSPECTED BY A DEALER WHO DETERMINED THE FUEL INJECTOR PUMP NEEDED TO BE REPLACED. AFTER THE INITIAL REPLACEMENT, THE PROBLEM PERSISTED. THE VEHICLE WAS INSPECTED BY A DEALER WHO DETERMINED THE FUEL PUMP NEEDED TO BE REPLACED AGAIN. THE MANUFACTURER WAS ALERTED. UPDATED 12/18/2006 - THE INJECTOR PUMP WHICH WAS REPLACED UNDER RECALL FAILED AGAIN. *NM THE CONSUMER ALSO WANTED TO RECALL FIXED, HOWEVER THE DEALER REFUSED TO HONOR THE RECALL. RECALL NUMBERS 96V057000 AND 03V159000. UPDATED 03/21/07. *JB

CONSUMER STATES WHEN DRIVING VEHICLE STALLS. DEALER STATES FUEL INJECTOR IS CLOGGED. *AK

VEHICLE SHUTS OFF WHILE DRIVEING GM KNOWS OF PROBLEM AND HAS REPLACED INJECTION PUMP AND PUMP MOUNTED DRIVER 3 TIMES SO FAR GM SPECIAL POLICY C00064 FOR 11YRS OR 120000 MILES. THE SAME PROBLEMS STILL EXSIST I HAVE A 9 PASSENGER IN ORDER TO TAKE MY KIDS AND FRIENDS TO SPORTING EVENTS ON ONE SUCH OCCASTION. THE TRUCK SHUT OFF WITHOUT WARNING A TRACTOR TRAILER WAS BEHIND US THANK GOD HE WAS PAYING ATTENTION AND NO ONE WAS HURT. THIS IS A SERIOUS SAFETY PROBLEM THAT IS NATION WIDE FOR 6.5 TURBO DIESEL OWNER. DT

WHILE REPLACING THE FUEL PUMP TO TRY TO FIX MY PROBLEM, I FOUND THE POWER WIRE (GRAY), MELTED INSIDE THE FUEL TANK. MAYBE IT GROUNDED OUT SOMEHOW, BUT THE WHOLE WIRE HARNESS IS BURNT, AND THE WIRE IS BRITTLED AND BURNT.*AK

THE WIRING IN THE FUEL TANK FOR THE FUEL PUMP GOT HOT AND MELTED SHORTING OUT THE FUEL PUMP. NLM

THE WIRING IN THE FUEL TANK FOR THE FUEL PUMP GOT HOT AND MELTED SHORTING OUT THE FUEL PUMP. NLM

ARCING CONNECTOR INSIDE FUEL TANK CAUSES FUEL PUMP TO FAIL AND LOSS OF ENGINE POWER. GM TECHNICAN REPORTED THAT HE PERFORMS AT LEAST 2 REPLACEMENT SENDERS + FUEL PUMPS/WEEK- INDICATING THAT " THE SENDER/FUEL PUMP CONNECTOR IS ALWAYS FRIED WHEN THE PUMP GOES". AS AN ENGINEER, I BELIEVE THERE IS AN EMINENT DANGER OF A FUEL TANK EXPLOSION PROVIDED PROPER AIR/FUEL RATIO IS ACHEVIED. VEHICLE HAS 42 GALLON TANK. MODEL YEARS 1999 ONWARD HAVE THIS ASSEMBLY ENCASED IN FIBERGLASS CYLINDER WHICH WOULD PREVENT FIRE/EXPLOSION. *AK

FUEL INJECTION PUMP MALFUNCTIONED, CAUSING LOSS OF POWER STEERING AND BRAKES WHICH NEARLY CAUSED A COLLISION. THE INJECTION PUMP COMPUTER HAS BEEN FAILING CONTINUOUSLY FOR 3 YEARS, GMC IS AWARE OF THE PROBLEM, AND IS ATTEMPTING TO REPAIR IT. *AK.ET.

FUEL PUMP FAILED, UPON INSPECTION OF THE UNIT MECHANIC FOUND THAT THE INSULATION WAS BURNED ON THE WIRING INSIDE OF THE TANK. WE HAVE HAD THIS NONE FUNCTIONING FUEL SYSTEM PROBLEM FOR OVER A YEAR. THIS WAS THE FIRST TIME IT COMPLETELY QUIT AND WOULD NOT START. IT WOULD SEEM TO ME THAT AMP DRAW ENOUGH TO MELT BACK WIRE INSUALTION INSDE THE FUEL TANK SHOULD BE FUSE PROTECTED! LAST TIME THE TRUCK WOULD NOT START THE DEALERSHIP WE USE IN CLINTON MO ( RAYSICK GMC, CLINTON MO) TOWED THE TRUCK IN AND ONCE INSIDE IT STARTED. BUT THE TRUCK HAS LEFT US STRANDED NUMEROUS TIMES BEFORE. *AK

WHILE DRIVING THE ENGINE DIES. WHEN TAKEN TO A CHEVROLET DEALERSHIP THE FUEL INJECTION PUMP WAS FOUND TO BE FAULTY. GM DEALERS HAVE NOT BEEN ABLE TO DIAGNOSE WHAT THE PROBLEM IS. THE TRUCK HAS BEEN BROUGHT TO THE GM DEALER 4 TIMES. *AK

PRESSURE REGULATOR/ FUEL INJECTORS/ FRONT DIFFERENTIAL SEAL FAILURE.

WHILE DRIVING VEHICLE DIES AND WOULD NOT RESTART. REPLACED BATTERY, BUT IT DID NOT SOLVE PROBLEM.
