2004 F250 6.0 with starting issues....

My buddy has an 04, when he first starts it up in the morning, he turns the key for the glow plugs and you can hear the buzzing, but it sounds different than mine on my 06, it sounds ... weak. Just buzzes funny. Truck starts up and seems to idle OK. If you try driving it, its sluggish and doesn't really run well at all. Once warm all issues disappear. We also found the wiring harness chafed right at the mass air flow deal under the intake elbow. He tried taping all the wires up individually as they were all touching. No difference. We just did an EGR delete on it and the truck runs 100x better now when warm, boost great and doesn't puke, but the rough idle is still there. FICM was recently replaced as well as new batteries, with no change (FICM needed to be changed because it died on the side of road). Anyone have any input with the funny glowplug noise?

This is just a guess but couldn't it be an injector. That would explain why it would run better when its hot. After its up to temperature the fuel would flow better .

Check the smaller cable on positive side of passenger battery. My 05 did the same thing and the 10mm nut that holds the glow plug power cable had come loose. Tightened it and 30k later havent had the same problem again...
