2001 GMC SIERRA 1500 Electrical System Problems

MY ABS CONTROL MODULE IS NOT FUNCTIONING PROPERLY. ABS IS DISABLED AND COSTS $1000 TO REPLACE. THIS IS A SAFETY HAZARD AS THE BRAKES CAN LOCK UP AT ANY MOMENT OR ABS IS DISABLED AND MAY CAUSE BRAKES TO LOCK UP. THE ABS LIGHT ON DASHBOARD IS ON CONTINUOUSLY AND THE MODULE WILL NEED TO BE REPLACED OR FURTHER DAMAGE WILL OCCUR. *TR

IT STARTED WITH THE FUEL GAUGE FLUCTUATING BETWEEN FULL AND EMPTY WITH A FULL TANK OF GAS AND THE ABS AND BRAKE LIGHT ON DASH LIGHTING UP FOR APPARENTLY NO REASON. THEN IT STARTED GIVING ME TROUBLE STARTING AND MAKING A WEIRD WHINING NOISE. I CHECKED ALL THE FLUID LEVELS AND FUSES, EVERYTHING WAS OK. I WAS AT THE CAMP(MIDDLE OF NOWHERE) AT NIGHT WHEN I NOTICED THAT THERE WERE SPARKS COMING FROM AROUND THE AREA OF THE STARTER WHEN MY HUSBAND TRIED TO START IT.(IT JUST HAPPENED TO BE DARK AND I WAS SITTING WITH A VIEW OF THE RIGHT WHEEL WELL) I CHECKED THE WIRES AND FOUND WHAT MIGHT HAVE BEEN A BREAK IN THE INSULATION, TAPED IT AND THE SPARKS QUIT. HAD NO CHOICE BUT TO DRIVE IT HOME THE NEXT DAY AS THERE WAS NO PHONE SERVICE. STARTED RIGHT UP , AND DROVE FINE, EXCEPT FOR...

I JUST WANT TO LET YOU KNOW ABOUT A LITTLE PROBLEM I'M HAVING WITH MY 2001 GMC 4X4 TRUCK. THERE ARE TWO CERTAIN GROCERY STORES I GO TO AND WHEN I START MY TRUCK BACK AT THESE STORES THE GAS GAUGE GOES TO EMPTY AND THE GAS PEDAL LOCKS UP AND CAN NOT BE PUSHED DOWN.THEN I HAVE TO TURN OFF THE ENGINE , THEN WHEN I GET THE GAS PEDAL FREED THEN START THE TRUCK BACK THE GAS PEDAL IS OK. I'M THINKING MY TRUCK'S COMPUTER IS GETTING CONFUSED WITH SOME KIND OF MICRO WAVES OR SOMETHING COMING FROM THE STORES ELECTRICAL DEVICES. I'M WONDERING IF ANYONE ELSE HAS THESE PROBLEMS. *TR

I BOUGHT A GMC SIERRA C-1500 PICKUP TRUCK, NEW IN 2001. IN SEPT '05, THE ABS LIGHT CAME ON & A HUMMING NOISE COULD BE HEARD EVEN AFTER THE IGNITION WAS TURNED OFF. THE ODOMETER WAS AT 50,000 MILES, AT THAT TIME. THE PROBLEM WAS THE EBCM SHORTED-OUT AND NEEDED TO BE REPLACED. NOW, 31,000 MILES & 3 YEARS LATER (81,000 TOTAL MILES), IT SHORTED-OUT AGAIN & NEEDED TO BE REPLACED. THE COST OF THIS PART ALONE IS $1,000.00 (+ OVER $200.00 INSTALLATION). THAT PART ISN'T EVEN SUBJECTED TO NORMAL 'WEAR & TEAR' LIKE BRAKES, BECAUSE IT'S NOT A MOVING PART. IT'S A COMPUTER MODULE THAT CONTROLS THE ANTI-LOCK BRAKES, THAT IS VITAL IN CASE OF EMERGENCY BRAKING, WHICH LUCKILY I HAVEN'T NEEDED TO USE. I DON'T KNOW IF THE EBCM (PART) IS DEFECTIVE ITSELF OR IF SOMETHING ELSE IS CAUSING IT TO SHORT OUT, BUT I DON'T THINK THIS...

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

THE VEHICLE HAD AN ELECTRICAL SHORT WHICH CAUSED THE DOOR AJAR ALARM TO SOUND AND THE DASHBOARD GAUGES TO MALFUNCTION. *JB
