• When ambient temperatures are below 0°C (32°F), the fuel tank pickup screen may be iced over from water in the fuel tank.
• When power enhancing devices have been attached to the fuel rail pressure sensor circuits, this DTC may set and adversely effect the fuel system components. (means hack/mods done)
• If the fuel pressure valve is not torqued correctly, the valve will leak fuel into the fuel return system causing this DTC to set. The fuel pressure relief valve uses a bite type seal, and proper torque is essential for valve to rail sealing. Refer to Fastener Tightening Specifications.
• A sticking FRP regulator may cause this DTC to set.
• High fuel injector return flow may cause this DTC to set.
• The addition of fuel system enhancements, such as auxiliary fuel tanks or add on fuel filters may relate to driveability complaints.

putting additives in to the fuel tank?

You take an have the code diagnosed an fix , then the light will go off .

DTC P0087: Fuel Rail Pressure (FRP) Too Low

Circuit/System Description
The fuel injection pump supplies high pressure fuel to the fuel injection rails, and then to the fuel injectors through high pressure pipes. The fuel rail pressure (FRP) sensor is a three wire sensor mounted in the right fuel injection rail. The FRP sensor uses a 5-volt reference circuit , a signal circuit, and a low reference circuit to monitor fuel rail pressure. This information is sent to the engine control module (ECM) to assist in the fueling of the engine.

Conditions for Setting the DTC
P0087
• The actual FRP is more than 15 MPa (2,176 psi) below the desired FRP.
OR
• The actual FRP is less than 22.5 MPa (3,263 psi).

Action Taken When the DTC Sets
• DTCs P0087 and P0088 are Type A DTCs.
• The ECM commands the engine to operate in the Reduced Engine Power mode.
• The message center displays Reduced Engine Power.

Important: Because of the cleansing properties of the biodiesel, switching from the straight diesel to a biodiesel blend can prematurely restrict the fuel filter with normal deposits in the fuel system. A fuel filter replacement might be required sooner than the recommended interval.
P0087
If DTC P0090, P0168 or P0191 is also set, refer to Diagnostic Trouble Code (DTC) List - Vehicle.
Ignition ON for 90 seconds, verify the scan tool FRP Regulator Command parameter is less than 20 percent.
? If greater than the specified range, replace the ECM.
Attempt to start the engine.
? If the engine does not start, refer to Engine Cranks But Does Not Run.
Install the CH-48027 to the fuel rail service port and slowly increase the engine speed until reaching wide open throttle (WOT). The value should be between 1-4 inches Hg vacuum.
? If more than the specified value, inspect for restricted fuel filter or damaged supply lines.
? If no restriction was found, test for high fuel return flow. Refer to Fuel System Diagnosis - High Pressure Side.
With the engine idling or at an idle, command the fuel pressure control to 180 MPa (26,106 psi) with a scan tool. Observe the Actual Fuel Rail Pressure parameter. The actual fuel pressure should be the same as the commanded pressure.
? If the Actual Fuel Rail Pressure is less than 165 MPa (23,931 psi), refer to Fuel System Diagnosis - High Pressure Side.
Important: If the fuel temperature is near 121°C (250°F) during the duplication of the complaint, or in the Failure Records for this DTC, inspect for a restriction in the fuel cooler air flow or the fuel heater always ON. Refer to Fuel Heater Always On.
Operate the vehicle within the conditions for which the customer complaint occurs while observing the CH-48027 . You may also operate the vehicle within the conditions that you observed in the Freeze Frame/Failure Records.
? If the vacuum was more than 12 inches Hg of vacuum at any time in the operating range, inspect for kinked or restricted fuel supply lines.
Operate the vehicle within the conditions for which the customer complaint occurred. Observe the Actual fuel Rail Pressure and Desired Fuel rail Pressure parameters with a scan tool. Fuel pressures should be the same for both parameters.
? If the Actual Fuel Rail Pressure is less than the Desired Fuel Rail Pressure, refer to Fuel System Diagnosis - High Pressure Side.
? If fuel system tests normal, refer to Diagnostic Aids.

You need a dealer, there is a real problem going on here, way over the head of any home do it yourselfer. The main reason is the special tools required to interface with the control modules that are throwing these codes

SES suction supply vacuum. GM BULLETIN #PIP4526. It's a vacuum hose that is getting hot under load and loosing its rigidity and collapsing. You gm dealer should be able to supply you with and updated hose. Ask them to print out the service bulletin to walk you through the repair.

Very odd. A Google search comes back with lots of "Duramax" hits . The code is: "Fuel System Leak Detected - Large Leak"
Some fixes that I found were replacing the fuel filter, others changed the FPRV (Fuel pump return valve?)
When you're pulling a trailer there is a much greater load (air resistance) even when just cruising. Empty or fully loaded, it's mass won't matter, it's the extra fuel required at every phase of your drive. If the fuel filter is getting clogged, it's possible that some sensor is showing a pressure that is beyond predetermined limits. Try the fuel filter replacement first to see if that fixes it.

Do you have a check engine light on? Have you done an engine control module fault code test (OBD2 control system), is fuel pressure OK under a load? Has the fuel injector spider manifold (inside the throttle bore) assembly been replaced, that is a known problem.

who did a conversion on this truck???? the duramax is a common rail engine and can not handle wvo or sve. it will destroy your entire fuel system in no time on this truck. if you want to do a vo conversion you need to get a diesel with an inline injection pump or one of the older powerstrokes. i would suggest you quit trying to run wvo through this truck if you do not want to do a lot of very expensive damage

Check your " FUEL FILTER " for clogging. Work backwards toward the fuel supply tank, Hope this helps.
