LBZ: Smoke and Codes :(

[Rascopermian]

My bone stock LBZ with straight exhaust is throwing low fuel rail pressure codes, and blasting black smoke like a crap tune on a power stroke. My fuel filter is new and unclogged.
So lets take a vote, who thinks it's an injector, and who thinks its the damn MAF sensor?:banghead:

I checked my flux capacitor, and the sodium rectifier.
the flux capacitor is capaciting the flux, and the rectifier is rectifing the sodium.

I am tired of looking for answers tonight, so I'll hop about to rap music the rest of the evening.
Maybe Lil Wayne will fix this:roflmao:

whats the fuel rail pressure? could be the cp3

 

[Rascopermian]

My matco computer wont give me pressure reading
Would it over fuel and cause the black smoke?

 

[2003dmax6701]

sounds like you have a injector is hanging open

 

[2003dmax6701]

need to get ahold of tech 2

 

[Rascopermian]

I think I need to go threw it and replace injectors anyways. I got 273,500 miles on it.

 

[Rascopermian]

I am checking eBay for one right now.

 

[Rascopermian]

Yup... It's an injector hanging open. Now to hunt for a set of injectors.

Is that on one set?!? I thought mine did well when it got 210k on a set.

 

[Rascopermian]

Yeah, one set. I have always ran a bottle of Sea Foam threw my fuel filter every time I changed it. Got any good ideas on who to buy injectors from? And..... Is it a bitch to replace them?

 

[usafduramax]

just out of curiosity how could you tell it was hung open? and to the guy above me you should be proud a lb7 made it 210k on a set on injectors......

 

[Rascopermian]

It's been black smoking really bad. #8 is getting louder.
I am glad it has made it this long on one set. Thats sweet in my book.

 

[usafduramax]

i'm really impressed(not being a smart ass) but i honestly can't tell my injectors apart in terms of sound..luckily your injector job is 1/10th of what mine would be in terms of time

 

[Rascopermian]

Are they not hard to replace on my LBZ?

 

[usafduramax]

i don't remember exactly what they did but i do believe they changed the location so they aren't as much of a pita to get to,i don't think they are under the valve cover like mine are....i think iirc that your job should take 6-8 hours maybe?

 

[Rascopermian]

Man I hope so

 

[usafduramax]

yeah man yours should be cake compared to a lb7

 

[Rascopermian]

Who sells the best injectors for our trucks?

 

[Rascopermian]

Do I have to pull the vavle cover to remove the injector?

 

[TheBac]

Not on an LBZ you dont.
