Car has been running fine and then started getting codes 171 and 174 and a little hard to start sometimes. Short term fuel trims at an idle run around 17 to 19 and max out at 25 when getting into the throttle pretty hard. Trims used to run (when running perfect) anywhere from -4 to +6 with the long term averaging around 1.
So just checking to be sure this sounds like fuel pump before I sock money into the fuel pump. It does run fine, but its been my experience of lean codes on both banks means restriction due to fuel filter and or fuel pump getting ready to toast out.

Thanks all....
