what does it mean?
code states:
An open or shorted condition detected in the auto shutdown relay circuit. An open condition detected in the ASD relay output circuit. An open or shorted condition detected in the fuel pump relay control circuit. An open circuit between PCM and fuel gauge sending unit. Circuit shorted to voltage between PCM and fuel gauge sending unit. No movement of fuel level sender detected

the fuel gauge if it gets down to 1/2 tank will drop down to E and then jump back up. and sometimes the truck will stall if im stopped. i just want to know if this is early signs of the fuel pump going?
