    SID 126 is the low side fuel pressure, FMI 1 is low. When is the last time you changed fuel filters?

    You may have gotten some bad fuel and the filters are plugging up. I'd try that first before I went further. You can also get that fault right after a fuel filter change from air bubbles (which is why I asked), but after 2500 miles, that's not the cause.

    Interestingly, I was driving and the fuel seemed to be stuck at a quarter tank. After 150 miles I realized this is suspicious, since it has to move at least a little after so many miles. I stopped to fuel, and after I fueled, the check engine light went off and hasn't been back on...

    Thanks for ur help
