06 wont start

Any codes? You know how to do the key cycle to check for codes? Could be lift pump and several other things.
 
is the truck stock ? mods ? There is no OE lift pump. Most likely it's something like a cracked fuel filter housing. Check and make sure the water separator isn't dripping.
 
Didnt realize I was posting in a gm thread. Damn fine print on tapatalk! Lol Carry on. Good luck
 
ive got an 07 lbz mine has been doing the same thing, But only in the morning after sitting all night. It will fire right up then like 5 sec. later it dies and just cranks then i crack the bleeder screw on the filter housing and prime it a few times and then it normally fires right up fine all day long untill the next morning. Im sure its an air in fuel problem i just cant find anything. So if anyone has an idea where to check i would love to get this thing fixed.
Thanks, Jared
