I have a 2003 GMC Sonoma 4CYL 2.2L with 140K miles. It has had a recurring issue where it is hard to start when the fuel gauge reads 1/4 tank or less. Usually have to knock on the fuel tank to get it to turnover. Recently replaced fuel filter, still the same. I thought that is usually indicitive of a faulty pump that is seizing. Additionally, I am continually battling a P0171 code in the computer. Is this all related to the same issue, or do I have multiple issues (fuel pump, 02 sensor, etc)?
have the same problem?
