Hello! #1; The injection pump inlet hose has been known to kink which will cause this fault...The line is foam covered...#2; Have you changed the Fuel Rail Pressure Regulator?
If so, the connector and its wiring may be open or resistive...The wiring is as follows...Purple White from regulator to ECM pin #42...Yellow from regulator to ECM pin #77...Check with an ohm meter set on X1 scale...Most important is the condition of the FRPR connector...Radio shack has a product called DOXIT...It cleans contacts by merely
spraying...No-touch cleaning...Excellent product...$14.95...Two spray cans (small) one cleans the other protects...Not much is necessary...Also clean the connector for the Fuel Pressure Sensor...Wiring; Tan...Orange/Black...And Yellow,,,
