My first thought would be the Under Valve Cover Harness (UVCH) plug that is prone to unplugging. Good news is, the drivers side is the easy side to check!

i might not have listed my thread correctly ,the driver side exhaust is always hot on number 8 and cold on 2,4,6 until you get it hot or drive it then they all get hot which it was already doing before i changed out 2,4,6 injectors for new ones , which were only 3 months old ,and when i put them in all good until week later let sit over night and now at start up pipe cold again and no power for awhile.anyone ever had this issue before ?

So you think those injectors could be stuck closed cold,I went ahead and changed out all 3 that didn't have oil coming out about 4 weeks ago because it was hard to start and when i did it cranked right up with oil coming out of all of them then about a week later and only after sitting over night cold exhaust again,its funny that those 3 are doing the exact same thing, the truck runs really good after you go 3 miles but before that barely moves then comes alive ,but at least it starts.
