Not sure what and/or code means or where to look to fix the engine is a 5.2L just bought the truck not real sure on the history, I do know it has a rebuilt trans, other than that the engine looks clean ( not dealer clean ).
DTC 27 Injector #1 control circuit. Injector output driver does not respond properly to the control signal.
Check wiring back to the computer and injector driver circuit

Running ok? Could be out of spec injector(s) or wiring/plug/ECM issue.
