What model vehicle & engine size is your Chevrolet ?
The first step in diagnosing this problem is to scan the engine computer for failure codes.In changing the fuel filter you must bleed the fuel system to remove all the air afterward.
Fuel System Priming
Note: In order for the diesel fuel system to work properly, the fuel lines must be full of fuel and contain no air. If air gets into the fuel lines, it will be necessary to prime the fuel system to eliminate the air before operating the vehicle. Air could have entered the system in one of the following ways:
There are many reasons why a computer controlled diesel engine will not run.
Here is one of them.
08-06-04-029C: LBZ, LLY, LMM MIL/SES Light On, DTC P0087-Fuel Rail Pressure (FRP) Too Low, Lack of Performance, No Power, Engine Runs Rough, No Start (Diagnose Fuel System Components) - (Jul 20, 2009)
This bulletin is being revised to advise technicians that all parts are to be returned to the WPC. Please discard Corporate Bulletin Number 08-06-04-029B (Section 06 -- Engine/Propulsion System).
Some customers may comment on an illumination of the MIL/SES with one or more of the following symptoms:
Upon further investigation, the technician may find DTC P0087- Fuel Rail Pressure (FRP) Too Low stored in the ECM.
A ceramic high pressure valve ball fracture inside the fuel injection pump may lead to internal pump damage resulting in low fuel rail pressure. This condition may contaminate the common fuel rails and fuel injectors with debris. The fuel injection pump may operate, but with reduced output flow.
A high pressure valve fracture may cause the fuel injection pump cup plug (1) to come out, resulting in a no start condition and a possible fluid leak.
Bulletin Diagnostic Tips
There are several bulletin resources available in the Electronic Service Information System (SI) that can provide the technician with information on diagnosis and repair of the fuel system. Some of the bulletins available in SI include:
Caution: Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel injection pump, or the connections. In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before disconnection. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.
Important: Make sure you clock in and record the actual repair order clock time when completing this repair. A copy of the repair order and a print out of the Engine Data 1 snapshot along with the fuel rail pressure graph may be required. Failure to provide copies of this information may cause your warranty claim to be rejected.
Start by diagnosing the fuel system components by referring to Fuel System Diagnosis in SI.
If the vehicle starts and runs, verify that there are no fuel pump inlet restrictions on the supply side by inspecting for kinked fuel lines or a clogged fuel filter. If the vehicle does not exhibit any fuel supply restrictions or the engine does not start, proceed with the following diagnosis:
Tighten Tighten the fuel pressure relief valve to 100 N·m (74 lb ft).
Tip You will have to manually exit the snapshot after 1 minute of recording.
