Ive got the only 6.0 with spark plugs.......
Hello all , well my truck that just had all of the injectors replaced and the EGR valve is running like it has a bad miss like a bad plug and wire,took it back to ford dealer today, and it turns out 2 of the injectors are bad already, go figure.so tommorow i get to drop it off again and have them replace the injectors that are made or remanufactured for better term in (MEXICO )replaced again.I know this sounds bogus but im telling the truth, this 6.0 is trying my paitence ,and as for the injectors, there not new, ford apparently dosent believe in (NEW) parts on ther trucks,that tidbit came right from the service manager....remans as he called them are alot cheaper.If i didnt have bad luck id have no luck and that sucks, sorry for the rant but this inconveinences me once again..FFF

ps wannabe,they hooked up the diagnostic computer,if thats what you call it,and the tech said number 5 ,and 7 were bad.then he did a compression check and said the compression was good.not sure if it was fuel ,or cylinder psi.

You do realize that aftermarket injectors are just remaned and modified stock injectors, so not being new isn't a bad thing.

Compression check is for the cylinders and isn't related to fuel pressure. I'm not doubting they found 2 injectors bad. However, this makes 10 injectors they've replaced in the process of repairing your truck. While it's possible they just got two bad injectors, I was under the impression that when you drove out of the service dept after the first round that the truck was running fine and then the problems returned shortly afterward. I would make them check the fuel pressure at both idle and wide open throttle (WOT) conditions. I think it should be in the 50-60 psi range at idle (although I might be a little low) and it really shouldn't drop below 40 psi at WOT (someone correct me please if I'm wrong here). Low fuel pressure will kill your injectors and it wouldn't be the first time that a faulty fuel pump has lead to numerous and repeated injector failures. That's why I keep harping on checking the fuel pressure. Maybe that was done during the diagnostic but I'd make them tell me if they did and what the readings were.

Actually the 50-60 psi range is if your running an aftermarket fuel system. Stock fuel pressure runs between 40-45(which is why the 6.0 is known for deadheading).

03 and early 04s, had 55 psi pressure no lower than 50 under load for me. late 04s and up the fuel bowl was redesigned and fuel pressure dropped to 50 max, no lower than 45 never ever ever.

That's not true, because mine was constantly at 45 long before I put the injectors in. Now could mine have been an isolated case because something was wrong that I don't know. My fuel pump didn't crap out til a year later after I did put my new injectors in, and nothing else comes to mind that would pose that much of a lose unless you can think of something else then a bad pump.

45 is low for me but normally when it is at 45 the filters need replacing, and if that doesnt help, it gets a pump. it should be 50 psi on the later models at KOEO and no less or there is issues. these trucks will live at 45, but lack power and only boost aproximately 20 psi.

hey all, Ill head the advice and ask them to to a fuel pressure check, but isnt that the job of the ford tech ? shouldnt they have done that already?when they had to replace the injectors .should I just go back and ask them to do this now?will they do that the truck seems to be fine now,as for ten injectors believe me or not thats the truth,i have no reason to make that up.and for my rant about new injectors, im not dissing any one or any place just found it odd that the service manager and tech would say about the injectors being remanned and made in mexico.like i said before im no mechanic , dont no too much about this motor but i have seen enough that i would take my old 7.3 over this motor any day. on one brighter note, that it matters my fuel milage readout went from 14.6 to 16.mpg dont no if its correct or not.

honestly i dont have to check fuel pressure every time. i can go by the way the truck runs and accelerates, then again, when i work on any truck for a performance concern i beat the living snot out of it when im done. there is a very good possibility that 2 injectors failed for whatever reason after the repair, i have seen them bad straight out of the box.

No worries FFF. Hopefully you're good to go. Just remember that not all techs are the same and I don't like to assume anything. Speaking of techs, we've got some of the best techs on this board!
