Diagnostic Trouble Code P0087
LBZ/LMM Fuel-Rail Pressure Troubleshooting
While the 2006/2007 LBZ Duramax powered trucks are generally thought of by many to be the best choice when buying a used GM diesel pickup, diagnostic trouble code P0087 is emerging as the single biggest negative for the LBZ/LMM as time goes by and mileage accumulates. The OBD II explanation for this trouble code indicates that the "Fuel-Rail System Pressure is Too Low", meaning the fuel rail pressure is below what the programming expects. As the 2006-2010 LBZ and LMM Duramax engines accumulate mileage and as the fuel injection system wears, more owners of these trucks are experiencing this problem during some rather extreme and sometimes not so extreme conditions. Let's look at what is causing this problem and discuss how best to deal with it.
