2007 running rough

First time posting. So far I have learned tons. Well the cold snap started and in the morning I went to start it up and after a few cranks the batteries died, so I charged them up and the truck would fire right up, because it was getting cold I started to plug the truck in overnight and it worked great for about a a week.well it started to warm up and I didn't plug it in now when it fires up it sounds and feels rough. There is no cel. And before it would fire right up now it cranks and cranks and then it will fire up after 5 or 6 seconds but it feels rough.. I did do a egr delete a few months ago , I check the ficm and it read 48 v. Anyone have any ideas?

cold start

From what I know, it could just be the powerstroke cold start syndrom with the hydraulic injectors. Also, normal start times are up to 2.5 seconds in normal weather and I think I read that up to 5 seconds is considered normal for temps lower than 32F. I could be totally wrong on that, but google it or search this site.

Also, does it run great when it is warmed up? If so, you could try two things. Rev-x, which worked for me and cleared up about 85% on day one and has been getting better.

They also talk about Rotella 5T clearing that up after several hundred miles of driving. I am going to try that on next oil change.

lastly, you could install new injectors. Probably only one or two giving you the problem. Shop can turn injectors on and off and isolate the problem to specific injectors and replace them....expensive though.

Sounds like they want some more of your money! You don't typically find bad HPOP's on '05+ 6.0's. You'll be looking at a high pressure oil leak, batteries, or FICM for the long crank. Does it crank long hot and cold?

I took it out last night for a hour drive..and it still doesnt feel right...at higher speeds it shakes a bit like its needing fuel + the long cranking time before it starts..if i pump the pedal like a madman then it starts faster...i think i might have to take it to a different shop
