some be my lift pump AND
 

my truck starting acting up again code was for voltage outta range on the lift pump and no bus to pcm so i read up on the no bus which is probably the cluster and they have a recall for the rear cluster wirng connector which ill see if mine falls into it and try that before i buy a cluster and im probably gunna get a fass pump.

FASS is a good way to go, I have had zero problems with mine.
As for the codes, I hope the wiring connector is the fix, and you can get it for free. Otherwise, you could be chasing wires.
