1994 CHEVROLET BLAZER Engine And Engine Cooling Problems

BY ANNUAL FAILURE OF ELECTRONIC "INJECTOR DRIVER" ON GM 6.5 TURBO DIESEL RESULTING IN FREQUENT STALLING AND ALMOST LEADING TO ACCIDENTS@INTERSECTIONS. UNIT REPLACED APPROXIMATELY 3 TIMES SLASTING ONLY 18 MONTHS OR SO. *AK

Mileage: 143,640

STALLS ABOUT EVERY HALF A MILE. GOING ON ABOUT 1 1/2 WEEKS. DONE QUITE A BIT OF RESEARCH TURNING UP MANY COMPLAINTS ABOUT FUEL PUMPS AND EGR VALVES. I DON'T HAVE MONEY FOR REBUILDING MY ENGINE SO I'D LIKE TO FIND OUT IF THERE HAS BEEN CONFIRMED ANSWER AS TO WHY THESE BLAZERS ARE STALLING. *JB

Mileage: 87,280

EGR VALVE MAKES CAR SURGE AND DIE ALMOST EVERY YEAR AND WE HAVE TO PAY SEVERAL HUNDRED TO CHANGE IT OUT EACH TIME. ($50+ JUST TO GET THE CAR CHECKED BY THEM SO THEY CAN TELL ME ITS A CODE 32-BAD EGR THEN 2-3 HUNDRED FOR PART AND LABOR). OF COURSE I STOPPED USING THE DEALERSHIPS AND WENT TO A SMALL BUSINESS MECHANIC AND CUT $100 OFF THAT. THE OTHER PROBLEM IS THE FUEL PUMP HAS GIVEN OUT TWICE BUT MY SON HAS FIXED IT EACH TIME FOR ME.

I HAVE REPLACED THE EGR VALVE 3 TIMES ON THIS VEHICLE. I AM HAVING TROUBLE WITH THE VEHICLE RUNNING ROUGH. I WAS TOLD I HAVE ALOT OF CARBON BUILDUP AROUND THE EGR PORTS AND THIS IS BREAKING/FLAKING OFF. THE DEALER SAID THEY WOULD HAVE TO TAKE THE CYLINDER HEADS AND INTAKE MANIFOLD GASKET AND SUBMERGE IN A HOT TANK OF ACID TO CLEAN THE CARBON OFF THESE PARTS. THE REPAIR QUOTE WAS $1600.00 AND THERE WAS NO QUARANTEE HOW LONG THIS WOULD TAKE CARE OF THE PROBLEMS I AM HAVING WITH THIS VEHICLE.
