@joshbradshaw229 I had swapped out relays for a known good one , it did nothing, that's when I started checking it for signal , power and ultimately ground

@jayjayltz ok good deal...I'm having that same prob...Did your starter gradually go out or did it just quit immediately?

Glad I could help

You are well

You are welcome

Thank you glad it was helpful

Glad it worked out

So you ended up connecting the relay with the wire or what exactly did you do…? 🤔

@alexisreyes1169 I ran a ground wire from the 86 starter relay pin to the body, and it started right up! And again, your video saved my life! 💯

Glad it helped

​@@osgdre7awesome

​@@osgdre7glad it helped

I would think it's a bad ground somewhere

@@jayjayltz thanks

@ConleyProduction thanks buddy you explained it perfectly

This problem just started, I did have a fire start under the fuse box did melt wires , took it to a place got it fixed , still have some lights on dash that I didn’t have before but , they got it running took it home , don’t drive it much but this problem just started, that the engine is not starting all the lights on like ur video but not cranking the engine

Awesome

It was tested plus swapped it with one that was known to be working

Ok just checking.. Thanks

That's awesome 👌, glad it helped, good luck!!!

Just started checking for power to the relay and also ground to it

08

not sure it will , but its the same engine so i dont see why not, just look and see if the fuse box is the same

Did u fix the issue. Same on my 2016 escalade

Thank you!!! Those were my issues exactly, blinking lights and all

Same did you figure it out

​@xxSNIPER230xx Mine ended up being the BCM (body control module). I swapped out with one from the junkyard. I have to take it to get it synced with the ECM in order for my radio to unlock and my check engine light to come off

😳😳

@@jerryramos1054 help I need to get to class😂

So tell me whats happening

Did you jump start it?

@@jerryramos1054 I thought it was a battery issue, but I jumped it nothing happened, called the dealership, said it MIGHT be the alternator so, not really sure not clicking or giving me any dash lights not nothing I have class later today, tommorow and the next day, my campus is very large and I’m in alaska so it’s really to cold to be walking to class everyday, would rather have my car. If anyone might have a soloution, hit me up

I believe if this worked than scs should be fine , if this issues was caused by a dead battery then yes the bcm lost its programming and you should be able to get it reprogrammed. Glad i could help

Yes in my case I had to purchase a used bcm because mine lost its programming when I removed the battery , so try this first and if it works then yea you probably have to have your bcm reprogrammed or purchase one programmed to your vehicle, lots of luck hope this helps.

Hey if you are getting a click out of the starter I would check the battery terminals and also the cable connections at the starter itself, so if you are definitely getting a click then there is communication from the bcm and might not need it , i would also tap on the starter with a light hammer while someone cranks it from the inside , could be a bad starter or loose wiring. Try that before the whole bcm thing.

Yes it is 100% fixable not hard to do either , this happens when you disconnect the battery from the vehicle, in mine to replace it. Once the battery is disconnected , the bcm looses its program therefore cannot communicate with the pcm and must be reprogrammed To the vehicle, a good mechanic will remove the bcm and either reprogram it at his shop if he has the software to do so or he will send it out to get reprogrammed, I know it sounds confusing but it is really simple . Jumping the relay is a temporary way of getting the vehicle started so you stay stranded

Sorry so you don't stay stranded

I'm going to upload another video better explaining this , on a chalkboard, look for it I will post it tonight

Thanks for answering my questions, really helps👍👍

@@rubioblas7390 no problem brother glad to help, also, I searched for the bcm on ebay and found that there are shops that offer a reprogramming service for these bcms you can send yours to them along with your vin# and they will reprogram it or you can buy a used bcm from them and provide them with your vin# and they would also program it. That's what I did with mine and it worked perfectly. If I remember correctly they charge like $75 if you send yours in and something like $150 if you buy one from them .

I had bought a new battery

I’m talking about the fuse box what tool

Sorry , I had use metal tweezers that I had laying around, you can also use a paper clip

Awe man good call going to youtube im glad it was a help to you guys thank you

I seriously would doubt its the bcm , if the bcm was bad it would never start or even try to start being it wont send the signal to the starter if it was bad. Being you already changed all the major parts , i would suggest going over the wiring at the starter make sure everything is nice and tight , especially the starter signal wire , from there go to the battery side and check that there is no corrosion at the terminals and make sure they are nice and tight, i recently had a honda that has the same exact symptoms i, i disconnected both battery terminals cleaned them ant the batter posts also undid the cables and cleaned them too (wire brush) and it soleved my problem the were loose and dirty. IMPORTANT!!!!!!! IN YOUR CASE WITH THE YUKON MAKE SURE YOU HAVE A CHARGER OR SOMETHING HOOKED UP TO THE WIRES SO THE BCM DOESN'T LOOSE ITS MEMORY OR YOULL PROBABLY END UP WITH THE ISSUE I HAD , NOT SURE IF THE YUKON WOULD DO THE SAME BUT IM GUESSING SINCE ITS GM ITS BETTER SAFE THAN SORRY . Try that and see if it fixes the problem, best of luck feel free to give ma an update thank!

@@jerryramos1054 thank you for the reply. I will try that out.

@@c7zftw777 no problem, sounds like something simple let me know how you make out thanks

@@c7zftw777 did u figure out what it was? Im having the exact problem except mine has not started and i have new battery and starter

It’s the negative ground from the battery to the engine block. Same exact happened to me. You’ll throw 100s at it trying to fit it try just replacing the ground cable first. Try jumpstarting it where the negative cable goes to the engine block.

In the end it was the body control module (bcm) which was the problem, the bcm controls stuff like starter signal ,door locks, alarm etc.

I changed the bcm (body control module) this is the part that controls stuff like alarm, door locks etc .

What's going on with yours

😄😄😄

Yes I tried everything b4 finding this out

Where was the bad ground at? Starting to have the same issues in my 2008 after replacing the hid bulbs.

This sounds very much like a bad starter , the next time it just clicks and no start , go under the passenger side and tap on the starter with a small hammer while someone turns the key to the start position, when you tap it and it starts then yes replace the starter. Be sure to check the wires on the battery make sure they are nice and tight and also on the starter while you are down there.

I’m having the same issues going to try that tomorrow if that’s the case hopefully is the starter

Im having the same issue but i have a new starter and battery can this be the issue a relay?

For all you guys i had the same issue, just clicks, i almost guarantee its a bad ground from the battery to the engine. Try jump starting it off the engine block where the negative from the battery goes. That cable looks totally fine but mine was totally junk. Buy a $20 ground cable and try it before anything major

Sounds like a loose cable or connection somewhere , these trucks are also known to have bad ground wire that ground the body to the engine , I've heard when this happens you tend to have issues like you are having. I would start by getting a couple of thick battery ground wires from your local auto parts store and ground one side to the body and the other to the engine one two different locations also make sure you clean off paint or anything from where your grounds are going to be so it ensures a good ground, if that doesn't work then move on to checking the connectors on your bcm (body control module) should be located behind the plastic panel under your steering wheel. Hope this helps

Just posted a comment for you I think I didn't hit reply but scroll thru here you'll find it

I meant to say bcm I ordered one thru a place in ebay supplied them with my Vin number and they program it

It was the bcm

I had to have it programmed

Sorry for the late response I hope you were able to figure it out

did you figure out what whas the problem

Hi markus007 did you solved the problem? I have exactly what problem?

Did not have to replace the relay no

No

Ultimately the problem is in the pcm , from what I understand it losses communication with the main computer so it thinks the vehicle is being stolen or something therefore it cuts off the ground circuit. You can order one on eBay you have to provide your Vin so they can program it . Then you will have no more problems, it's like 175$

i grounded it straight to the engine

Would any type of copper wire work

@@noahbryant4413 yes any should work
