Common fuel pump problems in a 2003 Mazda 6 include a failing fuel pump that may lead to hard starting, stalling, or loss of power during acceleration. The fuel pump relay can also malfunction, causing inconsistent fuel delivery or complete failure. Additionally, clogged fuel filters can restrict flow, exacerbating these issues. Regular maintenance and timely replacement can help mitigate these problems.
