NHTSA Complaint #10654028 — 2000 CHEVROLET MONTE CARLO

HAD TO CHARGE BATTERY SO I COULD TAKE CAR IN FOR IGNITION RECALL. SINCE I DON'T USE THE CAR MUCH ANYMORE. UPON TRYING TO START VEHICLE, ENGINE BACKFIRED AND UPPER INTAKE MANIFOLD EXPLODED AND PIECES ALL OVER THE DRIVEWAY. THIS IS THE SAME ISSUE AS DESCRIBED IN THE 2004 RECALL WHICH WAS PERFORMED ON THE FUEL PRESSURE REGULATOR. SINCE THE RECALL. I DID HAVE TO REPLACE THE FUEL PRESSURE REGULATOR AGAIN AROUND 2011. I ALSO HAD REPLACED THE UPPER AND LOWER INTAKE GASKETS THAT WERE FAULTY OEM PARTS. THE UPPER PLASTIC MANIFOLD WAS REPLACED TO THE NEWER DESIGN. ALTHOUGH IT BEING PLASTIC IS JUST AN ENGINEERING CATASTROPHE STILL DOESN'T SOLVE THE PROBLEM WITH WARPING FROM HEAT. ANYWAY. HERE'S MY DIAGNOSIS. FUEL INJECTORS CONTINUED TO SPRAY FUEL INTO ENGINE AFTER THE FIRST ATTEMPT OF STARTING VEHICLE CAUSED BY A WEAK BATTERY. I SAY THIS BECAUSE AFTER TURNING THE KEY OFF AFTER THE FIRST ATTEMPT I HEARD THE FUEL PUMPING FOR AT LEAST 10 SECONDS. THIS IS NOT NORMAL. AFTER 1 MINUTE I TRIED TO RESTART AND THATS WHEN PARTS STARTED FLYING. GOOD THING NO HELPERS HAD THEIR HEADS UNDER THE HOOD WHEN THIS HAPPENED. *TR
