Chevy Tahoe: Crank No Start

In this video I bring you through the process I use to diagnose a "crank, no start" on a Chevrolet Tahoe. I was told this happened right after the customer changed his power steering pump!? Could that be related to the issue? Let's find out. -Enjoy!

I remember when Eric had less than 2000 subs. Now he has hundreds of thousands. His channel is the same now as it was then. He just consistently makes excellent videos that are entertaining. How can someone be so consistent? Just one amazing video after another for years. Best mechanic on YouTube.

Towed from Massachusetts, diagnosed in 6 minutes, that’s why you’re a legend Mr.O. Cheers

[allanszast]

Big clue was it ran, put ps pump in then didn't run. Always go back to the last thing you did and double check your work. Usually you'll find the problem.

"Towed it all the way from Massachusetts." Holy loyal viewer Batman!!!

Seems if it ran before you did power serving pump and then it wouldn't run afterwards 1st place I would look would be down around that pump. Spend $20 get a service manual they are worth their wiring diagrams alone. I just replaced power steering cooler and pressure line on my 04 Silverado so very familiar with The vehicle and engine compartment. 6:40 in the morning cup of coffee and som sma.. Now time for work. Thank you Eric O for the video you in the family and Jason and josh, all stay healthy..

you make it look so easy, I notice you go to the manuals quite a bit and can see why you find the true problem over someone who just guesses's' what the problem might be. You do quality work. Nice job.

“What part of Suck-Squeeze-Bang-Blow are we missing?”

it is lovely to wake up on a Monday morning to a new SMA video. 😂🤓

[TheJmich]

And this is why you have almost a half million subs, top job as usual sir!

[VWWRENCHIE]

Another example of the well grounded service. and diagnostics techniques used every day at SMA.👍

[hatfez]

You're slowly becoming the king of the short videos. That's what happens when you're good!
Nice diagnostics, little fella!

[DIYDaveOK]

You know it's gonna be a great week when Monday starts with an SMA video notice! Thanks, Eric!

[sidwalker]

Mr O. even got everybody's Monday started.

[kirbyschneider]

I’d drive from St. Louis for him to work on my electrical. Even when you find the problem, you go further just to make sure. Very thorough. Professional.

Eric has saved me a whole lot of money and frustration using his videos to work on my 1999 Chevy Tahoe! I love this guy! Hero to the common working man

Great job, I've got a 2005 Chevy Avalanche flex fuel 5.3 just like that engine. Good to know info, thank you for taking the time to record it and share it with us. I can see why people would tow their vehicle to your shop hundreds of miles away. Good workmanship, you take pride in your work, you don't half ass it, you teach us how to do these repairs for free to us, your honest and have integrity my Friend something that you do not see very much of these days unfortunately. Take care and GOD Bless you and your beautiful Family Eric.

I watched my buddy do this exact repair yesterday on his 03 Chevy SS pickup. The only difference was his bad ground was the ground connection on the left side of the engine block shown in your diagram. He diagnosed as you did to reveal the culprit.This video was perfect to diagnose the issue. Awesome stuff here Eric! Thank you for all you do.

[XKBaller]

I literally just worked on a Silverado, same problem. My buddy googled for hours trying to find a vid like this. Great work

[d.ricc]

As a mechanic myself, knowing what the customer touched last is important. In this case, touched the power steering pump and then a no start condition, inspect the area for harness issues or wires left off like a ground. I knew when the mechanic said it's a ground issue, I said power steering pump, look there lol, good job because he knows how to diagnose an issue.

I grew up working on older vehicles (30's - 80's) so watching your videos is like exploring a whole new side to mechanics.

Wife’s 2003 Yukon Denali wouldn’t start for her several times. Each time I came home from work and tried it started. Confused on what could be happening I started researching crank but no start on YOUTUBE. Came across numerous sites, but not useful until viewing this site from Eric. Was planning to take into local mechanic tomorrow but thought let’s take a look at ground wire. Reached down, found wire and began moving a little. One little pull and up came the wire. It must have been barely attached. Spliced in new wire and grounded on top of engine. Turned key and engine started right up! Thanks Eric for taking the time to video and explain your repair. I’ve watched many of your other videos with similar success. Super helpful! Keep up the great work. You Da MAN!
