2018 Chevy Silverado Starter Relay & Fuse, Ignition Switch Bypass for Starter Testing

[@dalesilbernagel1306]

This video saved my butt! My family was stranded out in the cold, and the tip about swapping the trailer relay really helped me out! Thank you.

[@stevecampbell7620]

GREAT TUTORIAL!!!!! I am a 62 year old retired GM Tech. Very logical diagnostic. The way it should be thought out. Loved how you prepped the truck (labeled and color coded) to educate. If you are not an instructor somewhere you should be!!!!!

[@LehewTech]

Thank you sir! Never been hired as an instructor anywhere but I am happy to help others on KZbin.

[@frankyq21]

Bro yes!!! That’s how you flipping make a video. Straight to the point. Color coding and labeling. Little bit of safety tips. Thank you !

[@quintinlarrabee9869]

Helpful?! Bro that was one of the greatest breakdowns I needed to help a friend with his Sierra that I could possibly find! Please continue the good work sir.

[@user-id2qy4hn1k]

Great job man!! Saved me a big PITA. I noticed my remote start taking longer than usual to start my truck. I tried to start it last Friday and it wouldn't start at all. I know my ignition key had been getting unusually warm recently, so I assumed it was an ignition switch problem. I ordered a new ignition switch, then I saw this video. I pulled the relay and was getting ready to jump across the connections, while watching the video on my phone, then tried the trailer relay and my truck started right up. Thank you!!

[@user-kn4ci9lj4h]

Exactly what got me going!!

[@johnnash9072]

Thanks for helping me diagnose my no start issue. Being able to test the starter without potentially wasting time removing it first made me feel better about what the true problem is.

[@eugenebetke7188]

Just saved my day. Swapped relays as you suggested and it starts… Thank you!

[@12riveradavid]

When your truck wasn’t starting, did your dashboard turn on but engine not fire up? Thanks!

[@icantellfakefromreal]

@@12riveradavid yes, that is what a bad starter relay would cause. Dash lights up as normal but no click sound from the starter solenoid and a no crank

Thank you for the detailed explanation

[@ddrowdy7666]

Its a great way to pre-oil your motor before startup after a rebuild, or in my case after turbo replacement. Let it crank until the gauge shows pressure for a few seconds, do it twice then fire her up with full confidence that everything is lubed and ready to run.

[@FM-nl3jg]

Yes, thanks I will try this in the morning because my 2016 Suburban wouldn't start all of a sudden. I wish I found this video 1st because the others wasted about 1hr of my time.

[@anthonya6826]

My 2017 Silverado tries to start when I turn the key into the off position or sometimes if I put the key right into the ignition without turning it. Is there a way to diagnose if its the ignition switch or something else?

[@markatkins7480]

So I have changed my starter relay twice about 2 months apart. I’m still having issues starting my truck, does this mean my starter is bad or could it be the ignition switch? Thank you!

[@socanyou2714]

So if I do the jumper wire where the relay is and it doesn't turn over does that mean that fuse is bad thats on the passenger side battery?

[@chriscaldwell6477]

If all of this checks out, then is the starter the issue?

Nice labeling and color coding

[@ThomasPrunty]

This was great info. My problem is switched relays and no start. Hot wire jumper at relay terminals as shown in video and engine turned over. Then I replaced the relay and truck started repeatedly. Any idea what was the cause for the original no start

[@cstorer36]

I have the same truck and the same issue - ended up being a battery that wasn’t producing enough cranking apps but still powered everything else normally. That was two years ago and today it wouldn’t start again. I tested this method and changing the relay didn’t help, fuse is intact, so it could be the battery again.

[@user-sw1yw3df3i]

So what is wrong with it if you put the wire in and it only clicks?it also has a new battery in it!

[@roncoburn7771]

great video when i used the wire at the starter relay my truck wont turn over just clicks

[@LehewTech]

Have you charged and tested your battery?

[@stephenfarkasovsky7954]

My problem is sometimes it cranks and sometimes it’s great. It started doing this after charging a tool in my accessory outlet on the dash. I thought maybe a cell was bad in the battery but 75% of the time it’s great. Acts as tho the starter is engaged by a capacitor that’s charged to engage the starter but may be going bad because of not turning over at times. Could it be the relay?

[@stephenfarkasovsky7954]

Sorry I meant sometimes it DOESNT crank and sometimes it’s great .

[@user-ng6mi7ue5w]

Hi I have a model like this, and I could not start the engine and What is strange is that the transmission light does not appear in the dashboard I mean Interlocking letters And I couldn't figure out why plus before when I turn the steering I have annoying sound !

[@moisescastillo39]

I get how you tested it, but I can’t get over the fact that you seem to be connecting pin 86 to 87. From everything I read, pin 86(red) is the one that would receive power when trying to start the vehicle. So I’m not sure how your test works but I know it does because I saw another video do the same thing… so confused.

[@markberkos7899]

My starter connections were loose 2018 Silverado 39,000 miles.would not start, pulled back the wheel well and tighten the connection with 13mm.

probably wont get an answer before i get home from work today but i have an issue where i have 12V+ in my batter (seen on my voltmeter in my dash), go to turn the key and everything dies. not sure if im looking at a starter issue (normally theres a clicking with starter problems and i dont have the clicking sound) or if its as simple as needing a new relay. ill check when i get beck to my truck but ive never encountered a full dead reaction when the battery isnt actually dead...

I noticed that my starter has been cranking a little slower lately so I've been saying the battery is gonna hatch. So today after work I put the key in and the starter just clicked. So I assume that the battery is dead. Took it to get tested, they said it's junk. So I bought a battery, same issue, just clicked. So I found this video. Tried the first thing, that didn't work. Jumped the relay and it clicked. So I just kept doing that like 5x. Bow it turns and starts. Probably the starter, right?

[@Kingdom_Comics]

This literally happened with me. Everything you stated. I got home with the new battery. A few hours later, I remote started my truck (2017 Silverado) and it had a slow start but it started. I thought that was interesting, so I turned off the truck and tried to use my key. Now all lights come on but when I got to turn it. Just a click and nothing else...

[@trailerpark187]

@Kingdom_Comics yep. It was the starter for me. Literally when it did it the 1st time I had 37000 miles on it. Gm said, we don't cover that. I have random screws falling out of the dash and I think the trans gonna give up soon

[@michaelgallaway9024]

I have a 2015 suburban. I took it to firestone to get tires on it when I went to pick it up no crank no start they put a new battery in it and they said the starter was bad they put a new starter on it I drove it home the next morning got in it and tried to start it no crank no start again I know the battery is good and the battery took out was good. 😮do you have any suggestions.

[@LehewTech]

Perhaps a bad connection or a failed remanufactured starter

[@LehewTech]

Or maybe there was never an issue with the original battery and starter and there is another problem.

[@adamwhatley1120]

Hey same thing here did you figure out what it was

[@XxAviciiLevels]

@adamwhatley1120 I did! It turned out my starter was bad. Then, In the process of replacing it, I somehow damaged the plastic wire connector that connects to the starter. It had no visible damage, and still connected fine. I think the wire must have gotten pulled back or somehow wasn't making contact. I found a video where the guy said the plastic connectors fail/break constantly. He went on to show how to do-away with the connector, and add a basic terminal ring connection instead. It was very easy to do. So turns out my starter failed. Then I broke the plastic wire connector. I cut that off, added a ring terminal connection. New starter. Back in business. Good luck!
