LB7 Injectors

[Jackmchome]

As my 2001 2500HD just rolled 29K miles on the odometer I would hope for many more years of service. The injector question scares the heck out of me.
Can anyone provide an educated guess of the percentage of injector failure against the total number of vehicles sold?
Also the mean milage on the trucks that had the problem.
I would guess the true statistic, if it exists, is a close held company secret.

Thanks, Jack

Jack, I think it's all in the user of the vehicle. If you take good care of it, I think it will last a long time. My '01 is just shy of 60,000 miles now and I have had no problems and the way it runs and works I am not worried about it.

Jack, I have 66250 miles on my 02 and it has been to the dealer just once, and that was early in life, to get the TCM update.

Jack, remember your injectors are warranted for 200k miles. So after the 3/36 is up, you are only looking at a $100 deductible.

Don't kid yourself. It will happen. My 2002 ran great till the day they failed. All happened very quickly. I would say start to pay attention at around 75k miles. Just be thankful for the extended warranty.

I never noticed a loss of power or performance. Just drop in oil pressure and fuel in the oil. My first indication was a tank fillup where I only got about 12mpg.

Jack, You're going to have the same problem I do...that the waranty time (7 yrs) will expire LONG before you reach the 200,000 miles. My '02 just rolled over 26,000 miles. By the time my my injectors fail, I'll be long out of warranty. Too bad for us!

the injectors have a warrenty for 7 years or 200K on 2001 and 2002 dmax trucks. this covers cracks and ball and seat erosion. Cracks= fuel and oil in the crank case.....

Ah the lucky ones who for some reason get the special warranty from GM. I have a 2003, getting 8 new injectors as we speak. 86k miles. Started with an unstable idle a few months ago, not surging as with fuel pressure regulator (done that already). Then on Monday of this week I had a no start. Pumped the primer and it started right up (Knew about these symptoms from this site). Then again on Wednesday no start cured by primer pump. Took to dealer Thursday knowing in my gut it was the injectors. I didn't check the oil before taking it in but they tell me that is how they knew. Pulled the dipstick and presto, diesel fuel. They've already mentioned $100 but under my emissions warranty it should be $0, if I'm under 3000 hours. I just hope they have the injector thing worked out. Its not about how you take care of it.

So what I am taking from this is, if you have smoke at idle, it could be injector issues. I also have an 03 and just had this happen after I let it idle overnight for 6 hours. Not the first time I did that, but usually had fuel injector treatment in the tank of fuel. Didn't that time though and now it smokes at idle. I am heading out on a 7000+ mile haul today. I have 150,000 miles on the truck, are the injectors on some kind of special warranty for my year and mileage truck?
Thanks
