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 RU-vid.

@TheDisgruntledMechanic 3 года назад

at about 2000 subs when I subbed Eric. What I like now compared to then is he isn't afraid to do what he does! What I mean by that is he fixes stuff and isn't afraid to show using unconventional tools to do his job as he does it, critics be damned. This makes his channel stand out!

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.

@j.cooper2246 3 года назад

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..

@allanszast7579 3 года назад

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.

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 RU-vid. 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!

I have an )3 Silverado that had a bad fuel pump connector. Put a ne ACDelco pump in and all was good. I also put a new radiator and power steering pump in it. Drove 300 miles and it died and this time no spark. I watched your video and was able to find a partially broken ground by the power steering pump. I tested the ground at the coil pack connector and the test light was dim. I wiggled the wire and the light got bright at which time the truck started. I wiggled the wire and the truck would quit. Thank you for the video ! It saved me a lot of time !

Great, to the point video. In this case, no fancy diagnostic tests needed. About 90% of diagnoses in people can be made from good history taking(ie-it happened right after the power steering pump), a directed physical exam(let's look around that pump)and a thorough knowledge of, in this case, Tahoe anatomy.(what lives next to the pump?)

@johntuttle5396 3 года назад

First of all, let me say, that it is always something. And once again, your ability to establish what the "logic" tree for the electrical problem was, allowed you to quickly find that something. Which in this case was pretty obvious once you knew where to look. Your friend Scotty always says to "find a mechanic you can trust". Living in Massachusetts myself, I am not surprised that your customer had to leave Massachusetts to find a very "good mechanic". Here in "Mass" there seems to be way too many of parts cannon operators and "service techs"who don't like to get their hands dirty but have no problem charging top dollar for their lack of "service". On a separate note, I am secure enough in my masculinity to note that your nose seems okay to me. support. 😊
