What should common rail fuel pressure be?
Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines. On diesel engines, it features a high-pressure (2,000 BAR – 29,000 PSI) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors or pump nozzles.

What should a diesel fuel rail pressure be?
The pressure to deliver fuel from the high pressure pump to the rail/injectors at cranking is around 200 bars, at idle the pressure should be around 300 bars. When the vehicle is running the pressure ranges from 1200 bar to 2000 bar.
What does fuel rail pressure too low mean?
P0087
Diagnostic Trouble Code (DTC) P0087 stands for “Fuel Rail/System Pressure Too Low.” It may get logged by the PCM when the pressure inside the fuel rail or the fuel system dives below the minimum levels needed to supply the engine with enough fuel to run properly.
