My neighbor has the 2021 2500 HD Silverado and was having the exact same non starting issue. He had the battery replaced and it didn't resolve the issue. We ran across this video, tested out continuity and the 400 amp buss/fusible link had failed. He was able to track down a buss bar at an area Chevy dealership, picked it up, replaced it and he's now up and running. Thanks for making this video, it sure did save him a ton of money and headache.
Questions brotha my 2020 Silverado 2.7L is now doing the exact same but it started while I was driving and it told me engine power reduced and the engine began to shake so I turned it off and it’s doing this exactly, not wanting to turn on again any recommendations ?
The bus bar is just a plated & stamped piece of copper sheet. The copper path to the various studs narrows down beneath the black plastic to create fusible links. The 400 amp link on his had failed. It must supply the starter motor and there was a short or something that caused the link to fuse. The power to the starter solenoid coil must come from one of the other studs/fusible links as the solenoid still clicked. But the bus bar design is such that once one of the links fails, the entire part must be replaced. It can be tested by checking for battery voltage at the studs or by disconnecting the battery and checking for continuity between the battery connection and the studs etc. that are supplied. You could possibly jumper across a failed link for testing purposes only but that's rather risky on a 400 amp circuit. Unless the link failed from corrosion, not evident here, a short that caused a 400 amp fuse to fail is a serious issue. I'm surprised that replacing the bus bar was enough to solve the problem but if it works, it works.
I got a 22 Colorado.. 3.6 v6 I changed the starter.. It was involed in a front accident.. I only got a clicking noise.. Still not turning over.. Any ideas?
My 2020 silverado keeps draining my battery , I jump started my truck directly from there , And it drains my battery 2-3 days , should I changed the battery distribution engine compartment fuse block ? Probably blow the fuse
I got a 2020 Chevrolet blazer 3.6l V6 that was doing the same thing I replaced the bus bar because it had a blow fuse on it also replace the starter and nothing it keeps blowing the same fuse
I have a 2020 I can start it but it dragging like if the battery is low but the battery is good. Could I be having the same issue too. That it could be the bus bar.?
I saw this video and decided to change my buss bar as well. Easy to change but did not fix it for me. My 2020 suburban starts but hard. The battery is testing fine so I may still end up changing the starter. I really hope that fixes it. Because the fuel pump is next ugh... anyways thanks for this video.
That was exactly my problem after I changed the belts and idler pulley on my 2019 GMC Sierra. Almost changed my starter out before I seen your video. Thanks
Awesome!!! I got a 2020 GMC Sierra elevation 5.3 and yesterday mines started with the the clicking & slow cranking. Last night the check engine light came on & today no start. Got 12.5v at the battery. I thought about ordering a new starter, but this is making me think.
Could I try to jump the 450 amps fues using a thick gauge wire to probe the fuse is the problem, and make sure the starter is working? or, will bew too risky?

Would be nice if you showed the test procedure

On connector number 4 is there supposed to be 12v ? All connectors have 12 V but number four is dead. Is it supposed to be like that?

This video saved me, same problem with my 2020, 2500 HD, Duramax, replaced it, and it fired right up, thanks
I’m glad I found you because I was about to change my starter you get a like 👍🏽
This just got me home. Appreciate the video.

I Need your help
Is this part also called the BLOCK, BAT DISTRIBUTION ENG COMPT FUSE (INCLS FUSES)?
I can’t seem to remove the B and A black blue part
Could I try to jump the 450 amps fues using a thick gauge wire to probe the fuse is the problem, and make sure the starter is working? or, will bew too risky?
I have this problem with my 2016 gmc Yukon Denali
