#04-06-04-007I: Service Engine Soon (SES) Light On, DTCs P0087, P0093, P1093, Low Power, No Start, Hard Start, Fuel in Crankcase (Replace All Injectors - New Strategy for High Fuel Return Rates) - (Aug 18, 2008)
Subject: Service Engine Soon (SES) Light On, DTCs P0087, P0093, P1093, Low Power, No Start, Hard Start, Fuel in Crankcase (Replace All Injectors -- New Strategy for High Fuel Return Rates)
Models: 2001-2004 Chevrolet Silverado
2003-2004 Chevrolet Kodiak C4500/C5500 Series
2001-2004 GMC Sierra
2003-2004 GMC TopKick C4500/C5500 Series
with 6.6L Duramax™ Diesel Engine (VIN 1 -- RPO LB7)
This bulletin is being revised to advise technicians that 2001-2004 model year vehicles may be covered by Special Policy 04039. Please discard Corporate Bulletin Number 04-06-04-007H (Section 06 -- Engine/Propulsion System).
Condition
Some customers may comment on the Service Engine Soon light becoming illuminated. Upon investigation, the technician may find DTCs P0087, P0093 or P1093. Additional customer comments may include a lack of power, a fuel smell on the oil indicator (dipstick), fuel in the engine oil, fuel coming out of the crankcase breather, the engine cranks but does not run, or a hard start condition. This condition will not cause an engine misfire. Do not apply this bulletin to any diagnostic other than what is identified in the chart below.
Cause
The fuel injectors have internal conditions that may cause them to return an excessive quantity of fuel to the tank, as well as leak fuel into the crankcase. Due to the excessive return flow and/or leakage, the fuel injection pump may not be able to build up adequate fuel rail pressure.
Correction
Important: Before the technician begins diagnostics and repair, be sure to follow the guidelines in Corporate Service Bulletin Number 03-06-04-036A to avoid fuel system contamination.
Important: If the technician commands the fuel rail pressure with Tech 2® to 160 MPa at idle and it reaches at least 158 MPa, then this bulletin does not apply. The technician should then follow normal SI diagnostics. If the rail pressure does not reach 158 MPa, snapshot the data, then follow the diagnostics in this bulletin.

My 02 is in for it's second complete set of injectors. They were replaced in 06. What's the warranty when they replace them? They want $3300 as long as they don't break any lines. Should I plan on every 2-3 years spending 4K?
I would pull them out, have them properly tested and replace the bad ones. It's really not hard to replace injectors on these engines, just time consuming. Use GM replacements....
Not that bad of a job, here is a link to the write up I did, the last time I replaced mine;
http://www.dieselplace.com/forum/71...ews/279436-lb7-injector-replacement-pics.html
That was 110,000 miles ago and mine is ready for another set. But I am swapping out the LB7 for an LBZ.
