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.
Dealership found fuel pressure regular loeaking internally, they replaced fuel pressure regular with part number 19210686. Before I brought the car in I was getting 10-18 mpg city driving with A/C. Since they have worked on my car I am only getting 12-14 mpg city driving with A/C on. I looked up www.autopartswarehouse.com and they came up with different ACDelco fuel pressure regulator parts; namely AC217388 and AC172251. What can be done to get my mileage up to 16-18 mpg city driving? I have been getting that mileage since I purchased the vehicle.
We checked for leaks and there are none. Put in needed liquid refrigerant to run A/C. It is still blowing warm air. What is the next thing we can do? Thank you for your time and consideration
