Truck in limp mode! Help!

[Silverwolf]

My truck went into limp mode. Won't go over 60kmh. Computer says its a MID128 PID94 FMI1 . Says low fuel pressure. Does that mean the fuel pump packed it in? Had a similar code before but it was too much pressure, and a fuel pressure sensor repaired that. This is low pressure, could it be the same sensor or is it likely the mechanical lift pump failed. Still starts so the electric pre pump seems to work. Any help would be appreciated, Im stranded, or at least not going anywhere quick. Trying to limp to nearest city for help
