Chevy Suburban 5.3: Entire Bank Misfire

In this video I have a look at a 2007 Chevrolet Suburban that came in with a customer complaint of an entire bank of misfire. A quick scan of the vehicle revealed that it was having issues with all the coil control circuits on bank one. Powers, grounds, ECM? Let's have a look. -Enjoy!

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!

Nothing quite like watching an Eric O video with morning coffee on a cold morning. Thanks Eric!

Quite impressive the entire bank has a blackout 😂 and this guy diagnosed the problem in less than 10 min ... Truly a PRO ! 👌💯

[utfan]

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.

Eric, you are so fast, it's mind boggling, I had the exact same issue on a GMC pick-up only 3 days ago. My customer was told by a dealer that he needed a new computer! It's a good thing he decided to take it to me. It took me about an hour, but I used the same process.

[robertgreer]

It’s not boring I love watching! I wish we could see you watch the repair. You make it look easy! Great stuff …

As a pro wrencher myself, I can watch other people work all day - thanks for the videos, Eric!

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!!!

[jamesjones]

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.

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.

There are no boring videos on this channel !

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 YouTube 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!

[vehcor]

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.

[LTVoyager]

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.

[spelunkerd]

Like watching a surgeon at work, even as far as losing a needle in the patient, ha ha. I am constantly amazed at how quickly you zoom in to the problem.

[johntarver]

You and Ray make my day on y’all’s thorough repairs!

[andrianmonk]

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.

Watching Erik O while on vacation is still one of my favorite things

[DIYDaveOK]

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

[michaelpiecewicz]

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
