1993 Geo Storm Electrical System Problems

TL* THE CONTACT OWNS A 1993 GEO STORM. WHILE DRIVING AT ANY SPEED, THE ELECTRONIC CONTROL UNIT FAILED AND THE CHECK ENGINE LIGHT ILLUMINATED. THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 147,300.

MY 1993 GEO STORM HAS STARTED STOPPING RUNNING WHILE BEING DRIVEN AND LEAVING ME STRANDED. IT IS CURRENTLY IN THE SHOP AND APPEARS TO HAVE A BAD ECM. SOURCES ON THE INTERNET INDICATE THIS IS AN INHERENT PROBLEM IN THE MODEL CAR.*AK

93 GEO STORM RANDOMLY STALLS AND WILL NOT RESTART FOR SEVERAL MINUTES TO SEVERAL HOURS. HAVE REPLACED CAP, WIRES, ROTOR, PLUGS, PICK-UP AND IGNITION MODULE AND CANNOT FIND PROBLEM. I HAVE FOUND MANY REPORTS OF THE INSULATION ON THE ECU GOING BAD AND CAUSING PROBLEMS. *JB

MY 1993 GEO STORM HAS BEEN STALLING LATELY. IT IS TOTALLY SPORADIC AND DOES IT WHEN I AM PULLING OUT, WHEN IT IS IDLING, AND WHEN I AM ON A FREEWAY GOING ALONG AT A CONSTANT SPEED. THIS HAS PUT ME IN A VERY SERIOUS SITUATION A NUMBER OF TIMES AND HAS SEVERELY SHAKEN ME. IT WILL STALL IN THE MIDDLE OF AN INTERSECTION, AND LUCKILY ALL 6 TIMES THIS HAPPENED NO ONE WAS COMING EITHER WAY. I NO LONGER DRIVE MY CAR, AND I AM AFRAID TO SELL IT DUE TO THE FACT THIS WILL HAPPEN TO SOMEONE ELSE. I HAD CHECKED EVERYTHING I COULD THINK OF UNTIL I READ A ARTICLE ABOUT THE ELECTRONIC CONTROL MODULE BEING BAD IN 89-93 GEO STORMS, ISUZU IMPULSES, AND ASUNA SUNFIRES. I WOULD LIKE TO SEE A MAJOR RECALL PUT FORTH TO FIX THIS PROBLEM. THANK YOU.*JB

ON THE MORNING OF JANUARY 15,2003, MY VEHICLE, (1993 GEO STORM, 1.6L ENG, 152K MILES), SUDDENLY LOST ENGINE POWER ON THE FREEWAY. I REPLACED THE IGNITION MODULE AND ALSO THE IGNITION COIL. THE CAR STARTED FINE AFTER THAT. FOUR DAYS LATER, AFTER A 45 MIN. DENTIST APPPOINTMENT, MY CAR WOULD NOT START. AFTER 15 MINUTES OF TROUBLESHOOTING, IT SUDDENLY STARTED. I HAVE BEEN ENCOUNTERING THESE SAME PROBLEMS EVER SINCE.

VEHICLE WILL STALL WHILE DRIVING. CONSUMER BELIEVES THERE IS A FAULT IN ECU. CONSUMER IS VERY CONCERNED ABOUT SAFETY WHILE DRIVING.*AK

THIS CAR HAS HAD A HABIT OF STALLING WHILE GOIN DOWN THE ROAD, AT ANY SPEED( ONCE WHILE IN A SIX LANE HIGHWAY, CROSSING THE MERRIMACK RIVER, IN ST. LOUIS, MO. I HAVE HAD IT TO LEE KINSTLE CHEVROLET/GM, VAN WERT, OH, WINKLE CHEVROLET, PAULDING, OH, AND A CHEVROLET/GEO DEALER, IN BALWIN, MO. I CAN'T REMEMBER THE NAME. I HAVE HAD A COMPLETE TUNE-UP, INCLUDING PLUGS, ROTOR. CAP, AND PLUG WIRES. I HAD ALL THE WIRING GONE OVER TWICE. A NEW FUEL PUMP, TWICE, AND IT STILL STOPS AT ANY MOMENT. I AM AFRAID SOMEONE WILL BE IN A CRASH, DUE TO LOSS OF POWER STEERING, AND POWER BRAKES. CAN YOU HELP? I DON'T KNOW WHERE TO TURN!!

MY CAR HAS HAD AT LEAST 11 FAILURES DUE TO MALFUNCTIONING OF THE ECU IT'S BECOMING UNUSABLE THE ECU SHOULD BE REPLACED BY THE MANUFACTURER AT NO COST FOR ME.*AK

I'VE HAD THE ELECTRONIC CONTROL MODULE REPLACED THREE TIMES WITH A REBUILT ONE IN THE LAST YEAR BY AUBURN CHEVROLET OF AUBURN, WA. THIS IS AN INTERMITTENT PROBLEM WHERE THE RPMS CHANGE UP AND DOWN ON THERE OWN AND THE ENGINE USUALLY SHUTS DOWN. NO FAULT INDICATIONS ARE DISPLAYED. IT SEEMS TO HAPPEN MORE OFTEN WITH CHANGING TEMPERATURES. I ALMOST GOT IN AN ACCIDENT TWICE, ONCE ON THE FREEWAY AND ONCE IN AN INTERSECTION.*AK

HOW MANY THOUSANDS OF INCIDENTS MUST OCCUR BEFORE YOU PEOPLE TAKE ACTION.THIS SEEMS TO BE A WELL DOCUMENTED MANUFACTURING DEFECT WHICH CAUSES THE CAR TO RANDOMELY NOT START. PERHAPS THERE SHOULD BE AN INVESTIGATION INTO YOUR INVESTIGATION OF THIS MATTER, OR LACKK THEREOF. I HAVE FOUND HUNDREDS OF DESCRIPTIONS OF PROBLEMS EFFECTING THIS CAR INCLUDING TSBS. YET THERE HAS BEEN NO RECALL . WHY NOT? I AM FRUSTRATED AS YOU MIGHT WELL IMAGINE KNOWING THAT MY DAUGHTER AND HER SON ARE DRIVING AROUND IN A CAR THAT RANDOMELY BREAKS DOWN AND YET NONE OF THE SHOPS IS ABLE TO DIAGNOS THE PROBLEM. SERVICE BILL AFTER SERVICE BILL, FOR NOTHING. ONLY TO FIND A RECALL EFFORT REGARDING THIS ON THE INTERNET. CHANNEL 7 NEWS INVESTIGATIVE REPORTS WILL BE MY NEXT CALL, I WONDER JUST WHOS CAGE NEEDS TO BE RATTLED BEFORE THIS MATTER IS SERIOUSLY GIVEN THE ATTENTION IT DESERVES, OR ARE YOU WAITING TO SEE ACTUAL STATISTICS.. NO SAFETY DEFECT LISTED. *AK

IDLE BOUNCES AT 2000RPM. TPS AND IAC ALREADY CHECKED. SYMPTOMS APPEAR TO BE CAUSED BY FAULTY ECU AS DESCRIBED IN DETAIL AT THE FOLLOWING URL: HTTP://WWW.ISUZUPERFORMANCE.COM/ISUZUWEB/RECALL.HTML

THE ECU KEEPS MALFUNCIONING IN WARM WEATHER AS AS THE CAR GETS WARM FROM LONG DRIVES. THE CAR WILL NOT START AND HAS SHUT OFF WHILE DRIVING DOWN THE HIGHWAY. WE WERE VERY LUCKY OUR STEERING WHEEL LOCK DID NOT LOCK AS WE STEERED OFF THE ROAD AND TO A STOP. *AK

WHILE DRIVING THE VEHICLE LURCHES AND LOSES POWER AND STALLS INTERMITTENTLY WITHOUT PRIOR WARNING WHICH ALMOST CAUSED AN ACCIDENT. DEALER REPLACE ROTOR CAP/IGNITION WIRE/COMPUTER CHIP AND COIL, BUT CANNOT FIX THE PROBLEM. BEEN TO DLR 6 TIMES. *AK

WHILE DRIVING AT ANY SPEED, HAVE COMPLETE LOSS OF POWER. *AK

VEHICLE MAKES JERKING MOTION PREMATURE STALLING. CONCLUSION FUEL PUMP. TT

HI, MY NAME IS JUSTIN AND I OWN A1993 GEO STORM. I READ ON YOUR SITE THAT THEY WERE GOING TO RECALL MY CAR BECUASE OF BAD INSILATION SPRAY ON THE ECU OR ECM CHIP. MY CAR IDLES BELOW 1000 RPM AND SHAKES LIKE IT IS GOING TO STALL. *AK

WHILE DRIVING VEHICLE AT 35 TO 40 MPH VEHICLE STARTED TO LOSE POWER. ALSO, FLAMES WERE COMING FROM UNDER VEHICLE AND ENGINE COMPARTMENT. INSURANCE COMPANY NOTED CAUSE OF FIRE WAS DUE TO A WIRING HARNESS WHICH CONNECTS TO BATTERY AND ALTERNATOR. *AK

THE ECU SEEMS TO HAVE FAILED, IT IS A KNOWN PROBLEM WITH THIS CAR. I WAS DRIVING THROUGH TOWN AND CAME TO A STOP LIGHT, IDLE STAYED AT 2000RPM, NORMAL IDLE IS 800-1000. KEPT DRIVING. ON WAY HOME FROM ERRANDS CAR STALLED ONCE AT A LIGHT, TRIED TO STALL SEVERAL OTHER TIMES (ALL WHILE IDLING) WITH ENGING RPM DIPPING AS LOW AS 500 (OR 0RPM WHEN IT STALLED). FOLLOWING IS A LINK TO AN ARTICLE ABOUT THE PROBLEM. HTTP://WWW.ISUZUPERFORMANCE.COM/ISUZUWEB/RECALL.HTML ---- (ALL CARS LISTED IN THAT REPORT ARE SISTER CARS, WITH DRIVETRAINS BUILT BY ISUZU) I HAVE EXPERIENCED THE PROBLEMS LISTED THERE, EXCEPT FOR THE CAR GOING ON ITS OWN, AS MY CAR IS A MANUAL. THANK YOU FOR YOUR TIME IN THIS REGARD. THE EXHAUST MANIFOLD PROBLEM HAS BEEN KNOWN TO GM AND ISUZU FOR A LONG TIME KNOW, WITH VIRTUALLY EVERY STORM AND STYLUS ON THE ROAD HAVING CRACKED THEIR ORIGINAL EXHAUST MANIFOLD. THIS PROBLEM IS OBVIOUSLY DANGEROUS, AS IT ALLOWS NOXIOUS EXHAUST FUMES TO ENTER THE ATMOSPHERE AND ENGINE COMPARTMENT, BYPASSING THE CATALYTIC CONVERTER. ONCE AGAIN, THANK YOU FOR YOUR TIME. *AK
