My 2003 CTS would not start on the first, second or third try after filling the gas tank. Finally after several months of this occuring every two weeks a check engine light came on. It was the evac purge valve. Tom

The fuel filter on these vehicles is attached to the underbody, in
front of the fuel tank. Note that there are no service intervals for
in-line fuel filter replacement. Only replace the filter if performance
problems or troubleshooting indicates the filter is restricted.
Fig. Location of the fuel filter. Note a threaded fitting on the inlet and a quick-connect fitting on the outlet end.
Hope this help (remember rated this post).
