    My truck just randomly started acting weird, it started starting really rough then the check engine light came on flashing while running rough I believe it's the fuel pump something with the fuel but I'm not sure at the moment I started it but was hesitant due to being anxious of the truck breaking down

    But not sure exactly what it is if anyone has had this issue before I'm going to drop it off at my local shop tomorrow for a diag

    Cylinder misfire perhaps? Could be a bad coil pack. Could be a fuel issue as well although I wouldn’t think the CEL would be flashing for that.

    Had you changed the plugs before at some point?

    Glad to hear it. That should hopefully be a pretty straightforward fix.
