Everything below is an owner-reported complaint submitted to NHTSA about the 1999 Chevrolet S/T Blazer, grouped by the component NHTSA recorded on the report.

FUEL PUMP FOR 1999 CHEVY S-BLAZER 4 DR. MODEL. PUMP HAS BEEN REPLACED 4 TIMES WITHIN 8 MOS. FIRST LASTED 7 MOS. SECOND LASTED 4 DAYS, THIRD LASTED 2 WEEKS, SO FAR. WIRING HARNESS HAS BEEN REPLACED AS RECOMMENDED. UPON REPLACEMENT OF THIRD PUMP A NEW RELAY WAS INSTALLED AT THE RECOMMENDATION OF AUTO PARTS STORE. SECOND PUMP REPLACEMENT PRODUCED A TROUBLE CODE (CHECK ENGINE LIGHT) FOR EVAPORATIVE EMISSIONS, WHICH WENT AWAY WITH THE INSTALLATION OF THIRD PUMP. PARTS RETAILER IS STARTING TO GET HESITANT ABOUT REPLACING THIS PART, BUT HAS BEEN AS HELPFUL AS POSSIBLE. I THINK THEY ARE MORE EMBARRASSED ABOUT THIS THAN ANYTHING. PUMP WILL LOSE THE NECESSARY AMOUNT OF PRESSURE THAT THIS APPLICATION REQUIRES. COLD STARTS ARE FINE, BUT ONCE RUNNING AT NORMAL OPERATING TEMP. THE PUMP WILL NOT DELIVER ADEQUATE PRESSURE UNTIL ENGINE WILL EVENTUALLY STALL AND WILL NOT RESTART UNTIL TOTALLY COOLED. ORIGINAL PUMP QUIT ALTOGETHER AT 97,000 MILES, VEHICLE NOW HAS 104,000 MILES AND EACH REPLACEMENT PUMP HAS HAD SAME SYMPTOMS. *TR
