My truck has ben running sluggish, this morning I went out to start it, I put it in gear and when I did there was no acceleration? I could put the pedal to the floor and the truck wouldn't move, The SES came on, when I hooked up my scanner I had 4 fuel rail codes? Could this be injectors? If so didn't GM just extend there warranty on the injectors to 150,000 miles????

Any info will be greatly appreciated

Thanks,
Chris

What year truck? And do you have the codes that were in it? HTe extended injector warrenty is for the 01 to 03 lb7's up to 200,000 IIRC!

The truck is a 2003, the codes I left written down at the shop. It has 101,923 miles, just seemed like an injector issue to me.

Thanks,

When was the last time you changed the fuel filter? That could give you false codes for injectors too. I guess it would help to know what the codes were too.

I changed the fuel filter just a few weeks ago, I had an issue with the truck starting one morning when it was super cold(down in the teens, the fuel was not treated), the fuel jelled up. When I took the filter off(early afternoon) the fuel was stilled jellied and it was in the 40's. I guess once it jells it stays that way? But yes the filter was only a few weeks old.

Thanks,

Call or stop by the dealership and give them your vin # to see if in fact your particular vehicle is covered under the injector warranty.

The codes were for Fuel Rail pressure low, I cleared the codes and now the truck runs and drives fine. I think I am gonna replace the fuel filter just to be on the safe side.

Buy a bottle of Power Service 911. the bottle is bright red. It will re-liquify all jelled fuel if the directions are followed. Changing the fuel filter again is recommended.
