That code is the Fuel Level Cucuit Malfunction. I havnt read your other post but have you replaced your lift pump, that is generally the main cause to low fuel pressrure between the Fuel filter and Injection Pump, the injection pump can draw fuel on it own, but it overworks the pump and will lead to killing that pump. A new lift pump is about 160 bucks and takes only 30 minutes to replace.
