Chevrolet Impala LTZ 2014 Used Automatic Gasoline I have: 1/ Fuel pump 2/ Compressor I changed them in my car, and unfortunately, it was due to a wrong diagnosis and the problem was not from them. Whoever buys it, for honesty and trustworthiness, take it and install it. If it turns out to be working and there is nothing wrong with it, you can pay me a reasonable price for it, according to its value in spare parts and scrapyards. I don't want their price, but a reasonable price. It is original, from the dealership.
