2000 Chevrolet Blazer Q&A
2000 Chevrolet Blazer Question: What is the correct ACDELCO fuel pressure regulator part number for 2000 Blazer
I have a 2000 Chevy Blazer Lt 6 cycle 4.3L. Car has multiple fuel injectors controlled by the computer. We reported a miss and A/C blowing warm air. They put in fuel injection fuel rail fuel pressure sensor replacement. Part # 19210686 REGULATOR KIT. They reported "found fuel pressure regulator leaking internally, replaced fuel pressure regulator." I purchased the 2000 Blazer new and always got 16-18 mpg city driving with A/C on. Now I am getting only 12 mpg cycle driving with A/C on. Is the above part the correct part installed in my Blazer. I searched the internet and found www.autopartswarehouse.com. They reported AC Delco Fuel Pressure Regulators part nos AC217388 mfg # 217-368 and ac217251 mfg 217-2251 for my 2000 Chevy Blazer. Do you know what is causing the low mileage? Do you know what is the correct parts that should go in my Blazer. Thank you in advance for your assistance. Please respond at your earliest convenience. - Chevy2000
Have you talked to whomever it was that installed the replacement parts about this? How is the performance of the engine? If it were getting too much fuel, the light should be on with a rich exhaust condition! Is it? Was the original problem fixed by the replacement parts? Just need a little more info. because parts and their numbers are updated regularly. One more thing, was the fuel spider ASSEMBLY replaced? It doesn't have a fuel rail as you stated, we need to know exactly what was done to your vehicle to be able to help at all! - pushrod
FIRST, TO ANSWER YOUR QUESTION ABOUT THE PART NUMBER: I THINK THE PART YOU GOT HAD BEEN SITTING ON THE SHELF FOR A WHILE. I BELIEVE THAT NUMBER HAS BEEN SUPERSEDED AND IS NO LONGER A GOOD NUMBER. THE PART HOWEVER IS PROBABLY CORRECT. HAVE YOU KEPT UP WITH YOUR MILEAGE SINCE THE VEHICLE WAS NEW? WAS THE MISS YOU REPORTED FIXED BY REPLACEMENT OF THE FP REGULATOR? WAS ANYTHING ELSE REPLACED ON THE FUEL INJECTION SYSTEM? THERE ARE A NUMBER OF THINGS THAT CAN CONTRIBUTE TO A LOSS OF MILEAGE...HOW MANY MILES HAVE YOU PUT ON THE VEHICLE SINCE NEW? ALSO, HAVE YOU KEPT UP WITH YOUR MAINTENANCE ? - Rojo1
