Having the same exact problem with my truck don’t know what is going on with it

[@HebertsMarine-cb6wj]

With your video i was able to fix my dads 2005 gmc z71 by picking the coil ground with a needle and jump to alternator for ground and the truck started just as you said it would. my 78 year old father said he was impressed with my skills, and i said it was because of Advanced Level Diagnostics video. Thank you so much.

[@advancedleveldiagnostics]

That's awesome, Thanks for sharing!

[@beerwrenchgarage]

Exceptional video Man! Thank you for taking the time to show your analysis of the wiring diagrams. I learn something everytime I watch one of your videos.

[@advancedleveldiagnostics]

Glad to help, Thanks so much for watching!

[@PhillipBailey]

Ground is common to both banks down near the left motor mount bolts. I've had quite a few corroded off. Good diagnostic.

[@advancedleveldiagnostics]

Thanks for the info!

Why always customers spent money on parts canon at the end a tdch finds a silly problem and easily fix it ...😮it should be otherway round pay technician to get help and fix on less time and money...great job sir your info always help..cheers

💯 Thanks for Watching!

[@brakeboss]

Its a Chevy so its got to be a bad ground lol. Great Video as always.

[@advancedleveldiagnostics]

You got that right!🤣 Thanks for watching!

[@jdtractorman7445]

I love the one braided cable on the firewall that is already broken and missing. Those cables should never have been used on a vehicle. This is what I don't like about LED test lights. It takes just a miniscule amount of current flow to light one as opposed to an incandescent bulb.

[@advancedleveldiagnostics]

💯 agree! The test light I am using is an incandescent one that pulls 150ma. The only times I use LED is when I want to check relay control without actuating the relay.

[@brianmason8400]

I too have a headlamp bulb i use as a test light for more high ap circuits....ign systems, window motors, etc.

Thank for your time

[@chatobalencian1504]

Great informative vid I might be having the same issues now with my 04 Silverado gonna use this vid for reference also does it matter where u ground the injectors to new ground to engine or frame, would it be better to run ground to neg terminal on battery?

[@advancedleveldiagnostics]

I think chassis ground is fine as long as you test it before.

[@chatobalencian1504]

@@advancedleveldiagnostics thanks I appreciate and what exactly would I be looking for and what would I use my multi meter or something different I can use a multi meter if so what would I set it on and what # would be good for a ground and what's not good? Thanks a lot for your help 👍👍

@@advancedleveldiagnostics thank you. Any advice on training on more how to read and understand a wire diagram

Thank you for your awesome skills would you mind sharing what software data you’re using to look up diagnostics wire and schematics? I’m using Shopkey

[@advancedleveldiagnostics]

Thanks for watching! I am using AllData. I have Identifix and Shopkey as well, but this is my favorite for reading diagrams.

I rebuild alot of these 5.3s 2000-2006 gmc/chevy grounds are all in the same place. Theres 2 up top on back of engine and theres two on driverside lower part of block toward the front of engine.

[@reedcarpenter2994]

Do you consider them good motors? What mileage usually before you do the rebuilds?

[@joesmo4749]

@reedcarpenter2994 I like them 2000-2006 is the gen 3 I like those because they don't have active fuel management or vvt like the gen 4s which starts in 2007 and up. If the motor hasn't really been maintained like it should have been usually around 220,000 miles. But if the engine has been maintained I've seen them go way past 200,000 miles. My cousin has one in a tahoe they did the maintenance religiously and no lie it just rolled over to 500,000 miles, which blowed my mind!

[@reedcarpenter2994]

@@joesmo4749 that’s good. Is it a very expensive engine to rebuild? I’m looking at one with 200 k on it. Most used trucks under 20k seem to have around that on them and I figured might as well look at one with a good history of being reliable. I’m looking at a 2003 5.3 z71.

[@joesmo4749]

@reedcarpenter2994 good trucks, if you can find a good machine shop you should be able to build between $1200-$1500. I've got a good machine shop I've been using for many years. You can reuse the camshaft just check the lobes. I usually get the heads reworked the block checked with new cam bearings, rods checked and crank checked and polished up. My machine shop gets my engine kits and it comes with new pistons, rings, bearings all new gaskets. I usually put new pushrods in, a new oil pump is mandatory, new head bolts is mandatory. You will also reuse rocker arms just check them individually. Summit has the torque specs on there website for gen 3 ls style 5.3

[@jamesspash5561]

Check your brake clean or what ever you use. In our state the flammable stuff is being phased out.

[@advancedleveldiagnostics]

Good to know, mine is still flammable, but I'm sure my state can't be too far behind.

Must be California or Massachusetts.

Thanks!

[@spelunkerd]

Getting a chance to see professional workflow in real time is humbling. I can eventually get to the same conclusion, but it takes me hours to think things through, test assumptions, and go down the wrong pathways.

[@advancedleveldiagnostics]

Thank you so much! I appreciate you watching!

[@scientist100]

This is by far one of the simplest test; missing ground or power is always easy. Intermittents is where diagnosticians are tested lol

Could this be my po300 problem

[@advancedleveldiagnostics]

I would imagine you would have more issues then just a p0300, but it is possible

[@jackhammah1775]

@advancedleveldiagnostics appreciate the response. It sat for a year. I changed the transfercase. Po300 ever since. Changed alot of unnecessary parts same results. But didn't try or check this. Who knows critters could've been under the shield pan eating things.🤷🏾‍♂️ but thank you again
