Exclamation injector problems need help!

I have a 2005 f350 with the 6.0, I have head studs, EGR delete, fuel spring upgrade, SCT programming and 4" exhaust all the way back. I had head studs a new HPOP and IPR valve installed in March. I have had no problems since then until today I stopped at a gas station went inside, came back out and my truck was idiling really rough, and a little while later it just died.


I pulled the codes with my programmer and got these, P0263 cylinder #1 contribution/balance, P0281 cylinder#7 contribution/balance and P0683 glow plug control module communication fault. I'm assuming it's bad injectors? Where is the best place to purchase those? And should I just replace all 8 while I'm working on it? How hard of a job is it? And is there anything else I can try?

I would greatly appreciate anyone's help with this issue!
Thanks a lot,
Josh

What happened makes no logical sense. Stopping and fuelling doesn't create this scenario. Having a wire harness rub might. However, if this was missed with one injector not working quite right and the second injector made it more noticable, then luck wasn't on your side. The GPCM problem makes me think it might be more of wiring. Start by inspecting and moving the wires to see if it gets better or worse.

update..

I got my truck on a trailer and got it towed to my work shop and backed it off the low boy and it ran fine, then it started running rough again. So i popped the hood messed with the wiring harness a little and fired it back up and it idled fine for a short while then started running rough again and puffing a little bit of blueish white smoke, what could the smoke be? Im really hoping its the wiring harness's my FICM is holding a steady 48 volts like it should..anyone have any ideas?

My 05 did the. Same thing towed it home started and ran for a month then did it again it was the side rail fuel pump. Even the tech didn't think it was. The pump because of being intermittent.
