the only code that come up is for glow plug 4 p0674 is idk ??

 

????????

 

Is the turbo sticking? Are you getting a lot more black smoke than normal? I'd pull the EPB sensor and tube and clean that, just to eliminate it, and then probably yank the turbo and clean it...

 

ok i did the epb and the turbo was just cleaned it seems more like the fuel pump ??

 

What makes you say that? We need a lot more info here. What's your maintenance schedule for fuel filters and oil/oil filters? What brands are you using? If you think it's a fuel pressure problem you can test the fuel pressure, pick up a cheap gauge from harbor freight or something. You can just pull the upper fuel filter too and turn the key to see if it fills with fuel or not.

 

I just had my filter changed and I'm going up to a diesel shop witch is a firend of mine and he's going to test my injectors and put a fuel pressure gauge on it for me so after that I will have a better chance of figuring it out

once i know thos things i will get back to you with it

 

i had my fuel pressure check it was 65, i did the injector test and i need number 2 and 4 injector thats what he thinks the miss is ....

 

Very likely. If you've got fuel pressure and good ICP, that's really the only thing left. I'd pull them and inspect the o-rings on them too. If you do end up swapping them replace the o-rings and copper crush washers on all 4 injectors on that side so you don't have to dive back in and do it again.

Just to eliminate all possibilites before buying injectors... how old are your batteries? Have you tested the FICM?

 

MyBatteries are pretty new ones about 1 mouth and the otherone is about 6 mouths my ficm was tested at 48 to 49 votes to I'm thinkin it's good as well

oh and by the way do you know anything about the running gear in these trucks like tranfer case ? if there any good

 

Yeah most of the big trucks pushing 1000hp are still doing boosted launches on stock transfer cases... you have nothing to worry about there. The running gear is pretty stout on these trucks.
