2002 CHEVROLET AVALANCHE 2500 Electrical System Problems

VEHICLE STALLS AT HIGH RATE OF SPEED, HIGHWAY DRIVING, TRUCK HESITATES AND JERKS, AND COMES TO THE NEAR POINT OF STALLING, AND LOW SPEEDS, VEHICLE DOES THE SAME, HESITATES, AND JERKS, STALLS, ALL SYSTEMS FAIL. STARTS BACK UP UPON SHIFTING TO NEUTRAL. MECHANIC SAYS IT IS THE CRANKSHAFT POSITION SENSOR ON THE 8.1 L 8100 SERIES MOTOR, THE SAME MOTOR THAT IS IN THE 2001 MODEL SILVERADO, SIERRA, AND SUBURBANS THAT IS THE SUBJECT OF A RECALL. LOCATION IS IN THE BACK OF THE MOTOR MAKING IT NEAR IMPOSSIBLE TO CHANGE OUT WITHOUT MAJOR ENGINE REPAIR WORK, REMOVING INTAKE MANIFOLD AND OTHER COMPLEX THINGS, TO REPAIR AN APPARENT $60 PART. DANGEROUS DUE TO THE FACT THAT THERE IS ABSOLUTELY NO INDICATION THAT THIS IS HAPPENING AND HAPPENED ON A VEHICLE THAT HAS BEEN CARED FOR COMPLETELY.

2002 CHEVY AVALANCHE 2500 WITH 8.1 ENGINE DIES WITHOUT WARNING AT DRIVING SPEED. THE BATTERY LIGHT COMES ON, AFTER THE VEHICLE SHUTS DOWN, BUT NO CHECK ENGINE LIGHT, NO PROBLEMS WITH ALTERNATOR OR BATTERY CHARGE. NO SPUTTERING OR SLUGGISHNESS, NO WARNING WHATSOEVER. THE VEHICLE JUST SHUTS DOWN. WHEN THIS HAPPENS THERE IS NO POWER STEERING AND NO BRAKES FOR THIS 7K POUND VEHICLE! SOMETIMES, ONCE PULLED OVER AND SHUTTING EVERYTHING OFF AND TRYING TO RESTART IT WILL RESTART IMMEDIATELY, SOMETIMES IT TAKES UP TO 10 MINUTES OF TRYING TO CRANK IT INTERMITTENTLY BEFORE IT WILL RESTART. IT HAS DONE THIS TWICE IN THE LAST THREE DAYS AND A DOZEN TIMES AT RANDOM INTERVALS OVER THE LAST SEVERAL MONTHS I HAVE READ ON THE INTERNET OTHERS FROM WHO HAVE THE SAME PROBLEM AND MOST LIKELY SOLUTION SEEMS TO BE THE CRANKSHAFT POSITION SENSOR WHICH SOME SAY HAS BEEN RECALLED ON THE...

TL*THE CONTACT OWNS A 2002 CHEVROLET AVALANCHE 2500. WHILE DRIVING 60 MPH, THE VEHICLE WOULD INTERMITTENTLY FAIL WITHOUT WARNING. AFTER WAITING FOR A SHORT PERIOD OF TIME, THE VEHICLE WOULD EVENTUALLY RESTART. WHEN THE FAILURE OCCURS, THE BATTERY DRAINS SHORTLY AFTERWARDS.

THE FAILURE MILEAGE WAS 89,000 AND CURRENT MILEAGE WAS 93,000. UPDATED 02/10/09. *LJ UPDATED 02/11/09. *JB

ENGINE DIED WHILE DRIVING 60 MPH ON THE INTERSTATE IN SNOWY CONDITIONS ON 2 LANE PORTION IN HEAVY TRAFFIC. BY THE TIME I COASTED TO A STOP WITH NO POWER STEERING OR POWER BRAKES I WAS ON AN OVERPASS WITH NOWHERE TO PULL OUT OF TRAFFIC, SO ENDED UP BLOCKING ONE LANE OF TRAFFIC FOR ABOUT 2 MINUTES. OBD II CODE READER SHOWED NO CODE ERRORS. REPLACED FUEL FILTER. DID NOT FIX PROBLEM. AFTER CHECKING NHTSA SITE AS WELL AS OTHERS ON THE INTERNET FOUND IT MIGHT BE THE CKP (CRANKSHAFT POSITION SENSOR). TOOK IT TO DEALERSHIP WHERE THEIR DIAGNOSTIC TOOL VERIFIED IT WAS THE CKP. QUOTED PART AND LABOR TO BE $300 - $500. SAVING UP MONEY FOR REPAIR. *NM
