One of the first things I learned from my Uncle Gus was check the grounds. He was a truck driver but also a pretty good mechanic. He drove for a trucking company that had a truck that had been in the shop for a month with numerous electrical issues. He kept telling them that there was a ground problem and they kept telling him he didn't know what he was talking about. Finally they told him if he thought he was so smart, fix the truck. He took the main ground wire off the frame cleaned it and put it back on, truck was fixed!

There are no boring videos on this channel !

That was simple fix. Like he said all 4 wires or or coils going bad at same time highly unlikely. Nit impossible but just very improbable. Plus gm doesn't manufacture vehicles designed for the rust belt and Roberts your fathers Brother it's a bad ground.

Had a Wire Gremlin , Ghostly , Phantom issue in a friends 1994 Chevy 6.5L turbo diesel. Started looking at around dusk and was quit dark when i opened the hood. There was an strange orange glow coming from behind the head at the fire wall. Mind you i had turned all a/c full and headlights and everything power hungry on before i opened the hood. A single copper ground strap attached to the motor and firewall was glowing red enough to cook on. All 4 of the other grounds were totally corroded away. And with a mechanical fuel pump it didnt need spark. BTW the fuel bowl was just in front of it! Could have been a fire!!!

You really gotta keep them "Ground Relocation Kits" in stock here in NY. All brands and nationalities of motor vehicles are susceptible to salt, I've never seen any vehicle hold up to the salt for very long without needing attention. We are the worlds corrosion test lab. As the song says, "If you can make it here (NY), you can make it anywhere". This Suburban made it 14 years, which isn't bad at all. Many succumb much sooner. Thanks Eric, I enjoy watching even "routine" repairs, you always make it entertaining.

As someone that is a DIY guy, you have helped me diagnose and repair several issues with my vehicles. No video is too short, too boring or too long.

Hi, I'm the proud owner of a 2007 GMC Yukon Denali. I lost the whole left cylinder bank last night. I live in the Netherlands and the AAA, which is called ANWB, doesn't know anything about US cars. So there I was in the middle of nowhere with this rough idling car and all kinds of codes in my screen...and than I found this KZread video that told me exactly how to fix it! Man, I'm so grateful for your help. Can't thank you enough. Car is driving smooth again and it took ten minutes and a piece of wire...so again, thanks!

Absolutely love these videos. Too many technicians are more than happy to fire the parts cannon at problems with little to no success, all at the customer’s expense. So great to see methodical diagnosis to these problems. Great work.

Hey, I want to see the wire repair so I can read the comments from the "experts" on how you did it wrong! lol I just did this exact repair last week.

I am glad to see you fixed it right and didn’t just run a jumper to ground. That is a hack repair that often can cause unintended consequences. Almost always better to find the root problem and fix it correctly. Nice work.

You may consider it a boring video.. BUT... in this day and age where trades and common sense seem to get a bad rap, it's wonderful to see a person working hard and passing on troubleshooting/diagnostic knowledge... I'm a computer programmer and I do a ton of troubleshooting.. It's astounding the number of graduates that have passed by my desk that have no clue where to start when it comes to figuring out a problem..

Gotta love US auto manufacturers - leather "trimmed" seats, four compartment interior climate control, led mood lighting, satellite radio and break away ground connectors to ensure repeat business. Clever.

Not boring! Such a simple fix made necessary by low bid parts that cost owners $$$ when they fail and disable so many electrical functions. I am amazed by your knowledge and use of scanners to get the jobs done and save your customers $$$

Thank you for the location ive been with this issue for months on my rust crusty GMC with a5.3

Dont ever worry about a boring video as so far all have been intersting and educational

We’ve had a couple of Chevy box vans loose a whole bank. Turns out the fuse box was getting the green death and dropping power to the fuse that feeds a bank of injectors. Ended up just replacing the fuse box on them since it was all going green.

Thanks as always, Eric. I hope you, Mrs O, and your family have a blessed Thanksgiving!

I had a Suburban in the shop today (November 24), customer was complaining about “shaking, stabilitrack light on , and C.E.L lashing). Codes: P0352, P0354, P0356, and P0358, hard misfires on 2, 4, 6,and 8 cylinders. The entire bank. I thought “Why does this sound familiar?” Entire bank gone.... Suburban......even the paint color was the same! I gave the ground wires a wiggle and then tried to start the car: both banks were now out. New wires and an eyelet fixed the issue. Thanks for uploading this vid before Thanksgiving!

I for one do like to see the actual repair. Food for thought.

I think you did do a video before on the ground wire and I cleaned up the connections on my wife’s suburban and it fixed the problem. We have two suburban’s and electrical problems are the main issues for us on these vehicles. Still good vehicles though, 200k miles one one and 400k on the other. That’s pretty good!

Chevy's are pigs.

I don’t know if you still check comments on this video, but thank you so much! My wife’s 07 Tahoe’ entire drivers side bank went out, and I couldn’t figure it out. Ran a jumper from the black on the harness like you did, and as soon as I ground the jumper, all 8 fired. I changed the ground on the block by the power steering pump, but that didn’t do it, so I just cut the black about 4 inches from the harness and put a barrel connector in line with an addition ground wire coming out one end. Put an eye terminal on the new ground and ran it to a bold on the alternator bracket, and now she purrs like a kitten. Thank you!

Haha I just spent 3 days, between looking at wire diagrams, dreaming up tests, going with Haynes and Chilton manuals test to discover a bad ignition control modular. I was chasing 2 issues fuel? Ignition? Because no spark test lamp, no fuel presser gage. Sigh.... It was a crank no start issue. Finaly confirmed ignition tests called out the modular, replaced, hard start but start, so now fuel issue pump related shows no prime. Its a 96 GMC truck new to me so still learning it. Easyer then the newer stuff but way more electron crap then my 86 Toyota I had for 16 years every inch of. Shade tree mechanic skills, to poor to not be a DYI guy. Your videos really heip with a basic dioignostic tree. I appreciate that more then I can say. So Thank You, good job teaching, showing us how its done.

Gotta love corrosion and vibration! Nice looking vehicle with Planned Obsolescence in it's terminals. LOL!

AWESOME! You just helped me fix my truck, as it had the EXACT same problem with G102 except on Bank 2 (2-4-6-8). In my case the voltage between the black ground wire in the coilpack connector and B+ was 4.9V. I unscrewed the ground stud from the block and separated the eyelets. Then I bent the wires leading into one eyelet, and the eyelet fell off! That was the one that has both coilpack grounds crimped into one eyelet. The problem throws you at first because long-term fuel trim goes to 99% and it sets a lean code, yet the exhaust smells like raw fuel. The lack of spark on one bank dumps both raw fuel and unburned oxygen out of the exhaust manifold, making the O2 sensor read lean.

From salt water marine engines to salt on streets on long island ny I can tell you any wires which have 12vdc positive and grounds dissolve turn green in insulation and crusty at connection s. Just a matter of time . We spray all connections with CRC oil grease all connections ground spots. Excellent videos. Thanks Eric

You're a brave man, pulling that engine cover right off.. if it was me the heater core quick connectors would have immediately broke especially with rear heat LOL.

Love those boring electrical videos. Had my own 'bad ground' lately. Someone removed an A/M remote starter 👍 but forgot to hook up the ground he took off causing the push button start to set a code and trunk popper to not work. Easy fix after a quick look at a wiring diagram.

Never boring, Eric. Once had a Fire Dept Tahoe that was eating cats... not my diag there. When it got dumped on me, I found an intermittent wire in that harness connecting the coils (bank 1). Those Fire boys do run hard and when that B+ would drop out, that cat wasn't long for the world. Was glad to put an end to that.

Remember a similar video maybe a year ago!!! Just love the way you will show us again! Not the same but the same! Sign of a great teacher. Thank you Eric

I am not pro mechanic , but refreshment tutorials on your chanel are awesome, thank you

It’s not boring it’s Analogy analogy you have is unbelievable how you can find it that quick

Lucky the fellow came to you. I could see some shops throwing plugs, injectors, coils and anything else at it and still not fixing the problem.

NOT boring...not at all. Very informative, Eric, especially for those of us with 5.3 Chevies...... (and there are a million of us!)

Quick and logical diagnosis... I know that one thing I will be thankful for on Thanksgiving is the knowledge I have learned from Eric O.!

-- 2004 Tahoe here. Went all through the grounds when I first bought it for a winter beater. Also in another life I was a car audio installer: Simply put, you can never have too many grounds. I always double them up when I can.

Common sense is never boring! Nice job, deductive reasoning applied. Love the videos! Stay safe, and God bless

Might be boring to you but I watch and learn every time. 👍👍👍

Santa Eric sends this customer an early north pole gift. Man ... you got the magic touch down pat , Only took 20 thousands chevys and long nights to , make it look easy :) well done !!!!

Eric, please be assured.........this shit is NOT boring............keep up your good work

YOU WERE 110% CORRECT...THAT WAS MY EXACT ISSUE AND YOUR FIX.... FIXED IT!!!!! I have changed and added addtional grounds to the trany alternator engine etc. a year or so ago....but not this one. A grouind was also my problem back then with harrd trany shifting changing/fixing those fixed that problem. Thanks for this video. No one else mebtioned it...they went right to the cat as the culprit and that would have been around 2 grand to fix.

Being well grounded applies to many things. Eric may you and your family have a fantastic thanksgiving.

What are the odds LOL. Brought in a pickup 5.3 with bank 2 down last night. Did the exact same test and had the exact same issue. Going to fix G102 this morning.

I had one today on a Tahoe no ground on 1-3-5-7 also...done a ground 101 ..and she fired on all 8...watch your video last night to find a bad ground...thank Yu for your intel

Good job. If you would have done a quick jumper repair, it looks like they would have eventually lost the left bank too. Always fix a bad ground. If you get a 2002 era Dakota's with a no bus on the odo. Check the ground next to the ecm. 9 wires soldered into one ground eye.
