I have a 2010 Equinox 2.4 with a code P228D. I have replaced the high pressure fuel pump and after driving for a short time today the engine idled rough at park and stalled twice upon starting. The check engine light came on again (after clearing upon installation of new pump). Had the codes read and they are the same - P228D. Anyone out there who has experience this? If so, how did you fix it? Thanks Mike Majorana
