Hello All We have a 2010 Prius with about 203,000 miles that just displayed the following symptoms: - P0171 - LTFT sits around 23% all the time - Drives and runs as normal - Can smell fuel at cold start From what I have read so far it seems like the fuel pump assembly needs to be replaced. However, before I do that would like to make sure that there isn’t anything that I can look at before replacing the fuel pump assembly.
So far just seemed like there was some fuel in the you take manifold. Not sure was mixed with some oil.
