You have an 03 with a 6 liter and a chip? I do not recall an 03 using a chip. Everyone I know uses a handheld programmer or gets a tune.

 

yes, that is what I ment I have a Superchips programmer and when I plug it in to take the tune off the programmer it self will not turn on.

 

check your the fuse for your cigarette lighter

 

yea my cigarette lighter really cool I will give it a look thanks..
