I have a egr delete already

 

btw the timing i'm talking about isnt on the back of the engine i'm talking about the crank gear that turns the cam gear on the front, i know 7.3s have a problem with breaking the dowl pins just like the duramax's do thats why WOP tig welds the gear on the crank on a 7.3 to prevent it from slipping time, now i havnt seen a 6.0 do this but i would think that it is totally possible, the duramax that i did see do it drove into the shop with a fuel leak problem, shut it off and unknown to us the pin broke when the engine shut off, fixed the fuel leak and the truck would not start, no codes everything seemed to check out didnt figure it out untill we had the timing case off and was turning the engine over by hand and seen the gear move on the crank

may not be your problem since yours will start and is boost related but wanted to share that bit of info

 

I'll look into that only cam gear I can find on a 6.0 is in the rear. But thanks for the help

 

very possible that i'm wrong on the location of the gear because i've never had the timing case off on a 6.0, we've done headgasket jobs on them but ya dont have to go into there to do that

 

Yea the 6.0 has cam crank and hpop gears in rear. What a pos I'm hating my truck even more and the shop spent 6 hours on it and still no idea they said some thing about ficm and ghost codes idk just more bs and a pos ford that wonte run I might sell my rhino and d-stroke it I guess.

 

seinb/ Where are you located, someone on here might be able to help you look at it and it won't cost you anything, maybe, I have only seen one case like this, my sisters truck did this, it would only go to like 1600rpm, it was caused by the frame mounted fuel filter being gunked up from offroad fuel, the tank they got the fuel out of was dirty I guess.

 

I'm in southern Idaho. I posted in there section on here but no answer. The weird thing is it will drive fine if there is no boost all the way to 4000 rpm but if some one could help that would be great. The shops here can't figure it out

 

look on the pass. side of the intake manifold, there is a small black tube that goes to the boost sensor that is mounted above and to the left of the turbo on the cowl area, make sure this tube is hooked up, but I think it is if you are showing boost on your guage, still sounds like not getting enough fuel, double check the frame mounted fuel filter even though it only has 2500 on it, stranger things have happened

PS. check out// dieselmann's page// there is alot of good info on there, after looking at it you might want to check the screen in the fuel tube that is inside the fuel tank, could be clogged, that could be the reason you needed a new fuel pump, you don't run any bio fuel due you? not good for these trucks.

 

No bio and would the filters cause that instantly. I would figuer it would be a progressive thing not a instant one but will check for sure

 

It can happen quick, one day all is good then the next CRAP the 03s and 04s are the only ones that had an issue with the coating on the steel fuel tanks, it can flake off and clog the pickup tube in the tank,
by checking the filters it just eliminates that as the cause, sounds like a lack of fuel is the problem here.
