I have an 01 Duramax. I am currently having my injectors replaced for the 4th time. I have 141,000 miles and replace my fuel filter every 10,000 miles. This last time the factory rep stated that they were not going to replace them this time because the found water in the fuel sample from the filter and filter housing. I got into a very heated discussion that I felt it wouldnt matter if I did that because in a month they could go back and still find diesel in the water! Im not the brightest lightbulb, but I thought that was what the water separator was for in the filter? Anyways, I spent $500 to drop the fuel tank, clean it, and the injector lines and have them install a new GM filter. I picked the truck up on Sat. the 18th and drove it home. The very next day, under hard acceleration, (getting on a freeway) the power cut off. I took it back with a smile on my face and said "told ya so" The code they reset was 0093 (large fuel leak detected) Now they are replacing them for the 4th time. The first two times they were were replaced here and there. The last 2 times they are replacing all 8. The first time they replaced all 8 was back in May 04 at 118,000 miles. Now I am having them done again at 141,00. I NEED SOME SERIOUS ANSWERS PLEASE! Please don't BS with "I think" answers. I want some hard core facts, so I can have some "ammo" If i need to take this to a legal level to get this resolved! Thanks for your time!

I have an 01 Duramax with 141,000 miles. I am currently having all 8 injectors replaced for the second time. I only have 22,000 miles since they were done the first time! I have had a few replaced here and there prior to the new bulletins last May in regards to replacing all 8. THis is becoming a nightmare! This last time the factory rep told me I had to drop the fuel tank, clean all the lines and clean the tank, to insure that there was no "fuel contamination". THey now have a bulletin out that says you have to clean all that stuff before they will relace the injectors anymore! Anyways, they did find some water in the fuel filter and filter housing, so they said it was contaminated! BS! Thats why there is a water separator on the filter, but they were refusing to fix it unless I had everything clean! So if you can help, please help me! Please dont give me "what I think" answers, I need some hard core facts in case I have to take this to a "legal" level! I appreciate your help! Thanks!

what evidence do they have of contamination? They want to tear everything apart just to look? BS, find a different dealer. I have yet to see any TSB regarding the tank MUST be cleaned before replacement.

The only suggestion I have, is go to the injector failure survey thread here at the PLACE and contact all members that have had multiple injector failures.

There are obviosly two categories of people in that survey. Those that have injector problems one time and only one time and then those that have replaced 2,3 and 4 sets.

Either the injectors never were replaced, the fuel system is constantly contaminated, certain aftermarket equiptment or the engine or part of the engine is defective which is causing the failures.

Maybe you and the other multiple failure members can put your heads together and come up with a plan?

Mike, Your truck falls under the one's they've extended the injector warranty until 200K miles. You are way past the limit of most lemon laws, so basically you've got coverage for another 59K miles. After that you're on your own.

Doug

are you running a secondary filter? have you considered that you may be buying poor fuel? do you fill from your own storage tank?

Hi Mike,
Just curious. What part of the country are you located in?

It sounds like they just can't believe that the injectors could have gone bad again in 20k miles - so it must be "your fault". Print out the presentation on the california air resources board website - the one from bosch that says the fuel in the U.S. is "unfit for purpose" due to poor lubricity. It shows that the fuel system components could easily wear out in the 800 or so hours that you have put on your truck since the last injector "fix". Look here...

http://www.arb.ca.gov/fuels/gasoline/meeting/2003/022003bosch.pdf

We were supposed to have a new diesel fuel standard that would have made it a little better - but all major fuel pipelines have banned lubricity additives due to concerns about contamination of jet fuel (that uses same pipeline as our d2)... Winter fuel blends in colder areas of U.S. have extremely poor lubricity.

I am double dosing with stanadyne lubricity formula til the oil companies and the epa pull their heads out of their rear ends...

Please Don't post the same topic in two forums. Members and Techs read ALL forums.If you want individual Tech support please use the PM feature.

I have merged the two threads and will leave in the General LB7 forum for help

Thanks for the read

Sounds Like the dealer I use to work for. Junk. Oh if all us techs could statr our own show and traver the USA and fix them right...The more I work on the dmax the eaiser it is and the things we see all the time a gravy. Every once in a blue moor something crazy comes in and that only makes us smarter.

Jeff, I live here in CA. Ya I knows its a screwed up state, but Im stuck with it till I get rich and famous!

It wolud be really interesting to see if injector failures cluster in geographic areas - would certainly make a strong case for fuel if they do.
