Hey there, new Chevy owner and looking for some answers.  A couple of weeks ago I was getting off work and my truck would not start.  Tried jumping it but wouldn’t do it.  Had a relative come pick me up and when i went to leave, i tried to fire it up one more time and it started.  Had a few loss communication codes pop up.  Replaced battery that morning since it was 3 years old. 
 

Next morning same thing, no start then it started a while after.  

 

Next day after no start at all and wouldn’t start for a couple days.  Meanwhile it is cold, less the 40s all three times. Stablitrack service, Trailer Brake system, and low fuel warning was lit on my dash.  Battery voltage was good when check with multi meter.  Had U0100, U0101, U0073 all pop up when this happened.

 

Week after this problem started,  starter was replaced and all grounds and fuses are good.  After the day it was replaced, fired right up and ran good for a few days.  Then stopped starting for like a day, then hasn’t had any problems starting since.  

 

Fast forward, to this morning, same issue. No start,  everything was normal when putting keys in the ignition, all dash lights come up as normal.  Go to start and nothing happens, only check engine light stays on.

What year would be helpful. 

You say no start, does it turn over but won't start? Useful info.

And how many miles on your truck? Biggest issue with what you describe is Bad Grounds. Remove them, clean them & reattach. Even add some. 

 

 

Some good info here.

Start with the simple stuff before shooting the parts cannon.

I didn't watch the whole video but it didn't mention the ground strap behind the right front fender liner that is a very common problem.

It’s a 2018 silverado 15000 lt.  Has just over 120,000 miles on it.   When putting the keys in the ignition, dash lights up normally and goes through its process.  When going to start, it won’t turn over, and there is no clicking coming from anything when attempting to start.  No attempt from the engine when trying to start.

Could be several things. But my 1st thought is a bad starter. Try tapping it lightly to see if that makes any difference.

Replaced the starter a few days after the first day it did it.  Got the old one tested and was shot so replaced and still had the same issue.  Nothing plugged into the OBD port that can see either .

I would check the large fuse links on the battery power distribution fuse block that's on top of the battery next. See if any nuts are loose on the connector wire or any fuse blown.

Update:

 

Currently 54 degrees where I am and she starts up like normal.  Seems to only be when it is cold outside.  Would that change what i should be looking for?

New parts can be bad, including the battery. Have it tested, or put a voltmeter on it an watch how many volts drop when starting.

 

Next time it won't start; use jumper cables to create a ground from the engine to the battery. This will help rule out any bad grounds.

Did you find a solution.....?  I am having the same issue cold weather mornings vs warm weather mornings.

      OCI, not when but why?

      By PunchT37 · Posted

      I agree. That`s a LOT of sludge for 12,000 miles. I tossed that out here since this is an OCI thread. There`s tons of people here that do not post.   I used to work on a city fleet. That includes police cars and fire trucks. Lesson is, not to only use the odo for oci. A police car has a ton of hours on the engine for the miles it shows. And, not just idling, directing traffic. They beat on these things.   Course, since it is a Kia, they were gonna use the "100,000 mile warranty" for their OCI.😉

      Manufactuer's Defect - Paint Failure - Cherry Red High Country 2021 Suburban

      By AlVeron · Posted

      CLASS ACTION SUITS?  Does anyone know if there is already a class action suit for the paint - which was to have been fixed, changed in after the 2020 GM vehicles?  Does it look like this?    Just started 3 weeks ago - No help from GM as of yet - Dealer will not assist in speaking with GM on my behalf. Confirmed it is the paint they use along with the way the put it on that causes it to fail.  Clearly a Manufacturer's Defect.

      That dog don't hunt. 😏   First, a 2025 with 12K on the clock AND idled for a year nonstop is false on it's face; this is 2026. You can do one or the other but not both.    Second, ENGINE HOURS are absolutely available. The rest is third grade math. Micky Mouse scanner he got out of a box of Cracker Jacks OR an ID10T error.    Third, if they ran it out of oil "Several times" that motor is boned on the first hit.    Does this guy think piling higher makes it stink less?

      That's interesting, I assume that would add to the cost of the oil but also I was forgetting to bring up the issue of the low tension rings allowing more oil past which in turn forces the cats to have more oil additives pass through them that wouldn't otherwise so they are creating that problem and of course its all in the name of fuel economy. Mind you the other issue would be the lack of additives that fight the formation of carbon within the piston ring grooves which turn the engine into an oil burner and with in this GM forums case is your average off the shelf Dexos licensed oil, meanwhile the other off the shelf oil being Valvoline's R&P isn't licensed and the only one that is which is that certain Mobil oil that came out recently ( its not even being marketed in Canada ) and only a fraction of vehicle owners are going to be using it out of all the other oils on the shelf or the quickie lube bay that meet the Dexos spec by way of actual licensing.    Also I suspect that its an easy excuse to pool the non turbo DI engines in with the turbo DI engines and design the oil to not have LSPI issues in the most demanding engines and short change the naturally aspirated DI by not offering a higher concentration of additive package they could handle and still not be at risk of LSPI.    I wonder if Amsoil flipped the switch just lately and did whatever packaging designation at the same time as I wonder what oil formulation I would have bought in May, of course I don't know when it was packaged at the factory vs how long it was in storage at the Edmonton warehouse. I know its been said at least in the past that the big players switch over to a reformulated oil but the packaging has not changed until they make that move as well so there is that cross over time where its a new formulation in a predated formula marked package.

      Hmm. A real reason to not just use the odometer to determine OCI?
