Yeah they need to be replaced. JET chevy ran a diagnostic on them a few months ago for the guy I bought it from and they said the #8 injector was bad and since then the white smoke has gotten worse so Iím assuming another has cracked as well.

It sounds like injectorsdirect arenít a bad source  as long as you buy the Remanufactured and NOT the refurbished. And agreed, for a job this involved you replace them all at once.

I was told the injectors were originally replaced at 90k miles and now the truck has 190k so it seems about time to do it again. Thanks for the responses.

I have decided to sell it without doing the repair. I realize Iíll get significantly less because It wonít pass emissions as is and needs to do that in order to get current registration. Itís an 03 with 196k 4x4 crew cab. Very clean inside and out, spray in bed liner with matching canopy. Leather and Bose speakers.

Whatís is worth as is? $9-$10k? I see others 03s with similar miles go for $15/$16k.

Coach on here is a heck of a mechanic, I had him replace my injector pump on my 06, did a great job and was reasonable. Not sure what his business's name is, he's just north of Seattle I think.  @coach. Or. #coach
