hi everyone,

Sorry if there is another thread resolving this issue. So yesterday I replaced injector #8 with OEM reman. Was throwing a code for contribution. Anyway, after i replaced it about 10 miles down the road my truck sputters real bad and blows a ton of white smoke then stalls. I open the hood and unplug the ICP and try again. By the grace of God the truck starts and runs back to the shop where i have another icp that i slap on. About 40 miles later all power gets cut off. Literally everything just dies. No warning, all electrical cuts off with the engine. I pull to the side and it starts right up! Did this about 3 more times until I got where I was going.

So i turned the truck off for about 2 hours then fired it back up to head home. I turn on Torque Pro to monitor it on my way back and its giving me 4 codes at the same time "Cylinder Circuit High" for Cylinders 2,3,5,8. I feel like my harness is shorting out but wanted some advice! Please help! Oh and my parking brake light comes on randomly now lol
