I am on the receiving end of continuous calls over the past few years inquiring what to do

Jun 10, 2013 · My buddy has a 03 Duramax and we pulled our four wheelers with it yesterday

P0087 is a general OBD2 diagnostic trouble code that indicates a fault within the Pull the rail return line on the side closest to the front and see if its by passing fuel, should be none

It all starts in the tank, which is where the fuel is stored whenever you fill up

shut it off and crank to start right away, nothing, 500psi max pressure cranking, 65 psi KOEO Starts and idles smooth

The high-pressure fuel pump is mechanically-driven, usually by a special camshaft lobe, boosting fuel pressure to over 200 psi, depending on driver demand and ECM command of the pressure-regulating spill control valve

This signal is used by the PCM to adjust the fuel injector pulse width and meter fuel to each combustion cylinder

Dealer is still repairing the problem and I want all the information so I can at least fight a little!!!! Estimate for repair is 10 K

Low or high fuel pressure; Low or no fuel; Defective FRP sensor, circuit or connector; Defective fuel pressure regulator; Vacuum leaks; Excessive circuit resistance; How to Check

In a Duramax or Cummins diesel, a low-pressure pump first draws fuel from the tank and pressurizes the fuel to around 10 psi

Failure of this CP4 pump is usually catastrophic, causing metal particulates to contaminate the entire fuel system

This type of diesel injection is called a common rail setup and the FCA is what tells the pump to build more pressure from 5000psi at idle to over 22,000 The engine control module uses the fuel rail pressure (FRP) sensor to determine fuel pressure to the fuel injectors

It drove fine for around 300mi the next 3-4 Mainly the fuel return that is in the injectors themselves

If you unplug the fuel pressure regulator does the rail pressure max out? You probably need to get a pressure vacuum gauge at the test port for the fuel system in the front of the motor

During certain driving conditions the engine will perform a regeneration cycle, which will use additional fuel injections and the catalyst to heat up the exhaust Check fuel pressure at injector rail

Typical causes for low fuel pressure include a dirty fuel filter, weak pump, incorrect tank venting, restricted fuel lines, a clogged pump inlet strainer and faulty electrical control

Apr 13, 2014 · At highway speed 65mph DIC says change fuel filter, engine went to limp and threw "generic low fuel rail pressure" code

he has the fuel rail fittings and a lift pump and a new fuel filter multiple times to try to fix it

DTCs related to a bad fuel pressure regulator: DTC P0087 Fuel Rail Pressure (FRP) Too Low DTC P0088 Fuel Rail Pressure (FRP) Too High DTC P0089 Fuel Pressure Regulator Performance DTC P0090 Fuel Pressure Regulator Control Circuit Eliminate Low Fuel Pressure caused by Leaking Relief Valve

Use the EN-47589 (same block-off caps as #9011 SPX Miller Get consistent fuel rail pressure from your 2004

Diesel Fuel Injectors Probably because of the early Duramax LB7 injector issues I mentioned at the start of this article, the fuel injectors are by far the component that causes the most concern among vehicle owners

Collapsed or kinked fuel line problems restricting fuel flow to high pressure (for GM vehicles 2001 to 2004

Almost every modern fuel pump has that 'sock' or screen on it, sounds very similar considering the fuel tank fill level is a factor in your case

Over time, Fuel Coolers may begin to leak, as well as rust which can contaminate your fuel system requiring costly repairs

The dual fueler option is $2000-$3000 depending on if you choose a kit with or without a pump, and whether or not you want a modified CP3 or a stock one
