Hi Guys:

I have a 2003 Sierra LB7. I bought it in July '03, and in January, '04 at 14,000 miles, I had an injector go bad.

At that time they did not have the "replace eight" policy in place, and they only swapped the one injector, all under warranty.

Fast forward to now. I have 65,000 miles, and it's been over five years since I bought the truck, and it will be five years since they worked on the injectors here soon.

What I see is that I'm going to hit the seven-year mark before I hit 200,000 miles so I have two questions:

1] Does the clock start at purchase date, or at repair date?

2] Does the fact that they already did injector work nix the seven-year limit? My bro-in-law, who has a 2001, is on his thrid set and he says it's all being done under warranty even though he's past 7 years.

I'm thinking I should start checking these suckers if they're covered still so if I need a replacement I can get it before GM goes TU.

Thanks for any comments.

The warranty starts from the service date. They are covered regardless how many times they were replaced. As long as it's still in the warranty period. Or unless they can prove that your air freshener caused them to go out. J/K

Hmm.

Are all eight warranted from the service date? Or just the one?

All 8 are covered from the in service date of your truck(the day you bought it). the warranty on the single injector ran out when you passed the 5/100k mark, from there you have 2 years and the reminder of the 200k.

So, the injector that was replaced has less of a warranty than the new ones? That doesn't seem right. If I'm reading it right, the single has expired if it's 5 years from purchase date, or will expire in January if it's 5 years from the warranty replacement date, and yet the original other 7 will be warranted until I get to 7 years from the in-service date.

Or am I understanding this wrong?

7yrs/200,000 miles from service date of vehicle. No matter how many times they have been replaced. If you have 199,999 miles on it, it's covered. But as soon as you hit that magic number. It's over. Even if it was replaced at 199,999 miles. Hope this explains it better.
