Lb7 Fuel Pressure Regulator Code at Ann Verna blog

Lb7 Fuel Pressure Regulator Code. Is it throwing any codes. If so, i would suspect fuel pressure regulator. Rail pressure was jumping around. This guide will demonstrate the procedures to install the lbz/lly fuel pressure regulator in the lb7 duramax. I cleared the codes and the fuel pressure regulator code p0089 came back after a few min. Now the surge is almost continuous and i recently got a check engine. P0090 is fuel pressure regulator related, not the rail pressure sensor. Break the signal wire between the sensor and the ecm and monitor what the sensor is reading while the apparent pressure change. It could let fuel bypass which could cause the rail pressure to not be where it needs. What is every code you have? It throws the codes p1093 and p1094 for fuel pressure low under no load and fuel pressure low under load. You either have a sticky fpr,. The time taken to accomplish this was around 1.5 to 2 hours. Initially it was just an occasional sudden surge at idle.
