That was a lot of work and it's not easy to make a video to help us learn. There does seem to be grounding issues that can cause many problems or even leave us stranded. Just bought a nice '04, Z71, Burb with little rust that had some gremlins. Thanks to Y.T. vids I found the Black/White stripe ground wire on the back of pass. head that someone put a crimp eyelet making a bad connection. I cut it off, soldered a tin coated wire designed for cars/boats on and ran it to the body ground terminal which has the braided ground strap to the block. Cleaned everything good, checked braided strap for good ground and used electrical grease. Also fixed hood ground. Truck starts great, Check Engine light finally went out and the BOSE system now sounds fantastic. I'll continue cleaning other grounds. What's very helpful in these 2 vids is we can know where ground wires in harnesses are located and what they are grounding. Very useful vid and nice job putting it back together.

Thank you helped me out alot

Check the ground wire mounted behind the drivers side pillar on the dash

I just fix mine but you can run a new ground from the coils big plug ground to a good engine ground

Man I just changed my oil pressure sensor and now my truck doesn't start it will crank but will not start I think I might have either pulled, disconnected a ground by accident and I was looking at my ground on my battery and its original but there is the big thick cable ans a smaller gauge wire thats split so i need to check my wires just kinda hard been cold as balls and windy no shop just outside and been frustrated my truck was working fine before the oil pressure sensor I really hope I can fix this I only have this 1 vehicle right now any input would be appreciated all I disconnected when I replaced oil pressure sensor was that little pig tail on middle right under the vortec plastic it's black and baby blue right by the other flat braided ground anybody know what that's called?

Does driverside and passenger side coil packs have separate grounds?
