I picked a 03 5.3 last week from the junk yard. I got the motor installed and the injector connects are same as my bosh 60lb injectors. Did they change injector connects in 03 or are these flex fuel injectors.
Here are some pic's

This is from the lisatahoe pdf from S&P.
not sure if it helps
The 2002 LQ4 I grabbed the other day has the flex fuel style injectors, not sure if they even had flex fuel in '02 tho
-edit
yes, they did have flexfuel on the 6.0 in 2002.
answered my own ?

LQ4 never came with flex fuel from the factory. Either someone put them in there, or its not a LQ4.Originally Posted by haveTBIwantLS2
To the OP. Your first 2 pictures there are flex fuel. The regular injectors were the same all the way through.
o what the hell.
now I have something else to wrry about.
Yah, I was wrong about my edit.

What is the part # on your injectors? and it says 6.0 on the block right?
yah, 6.0L cast right on the #1 cyl. 317 heads.
There was a catalyst info sticker on the black plastic cover that again identified it as a 2002 6.0.
Maybe GM used that plug style in 2002 and just picked that one for flexfuel in later vehicles??
I don't want to thread jack...
don't have info on p/n right now. blue O rings on the injectors, tho.
I tried to take a pic earlier today but my phone couldn't zoom that far in on the inj.
ENgine is at different location than me

33.05 pph
yah, there are small differences between the two injectors in the tunes.
I just looked at them both
Flexfuel has less minimum PW time
regular fuel has as a smaller default min PW
flex has a larger small pulse adjust
