About 6-weeks ago we were at our property camping and experienced our first issue with this truck. Weather was cold, sub freezing, but not below zero. Truck would not crank over. After turning the key a few times truck fired up and we wrote it off as a one-off occurrence. 

 

Fast forward to today the truck has repeated the issue several times without rhyme or reason. We've tried both keys, flipping key 180, and remote start. Truck will not turn over but fuel pump primes. Then after a minute or two the truck fires up. 

 

When the truck didn't turn over yesterday I checked battery voltage - 12.59v. Today I checked the battery and 12.29v and starts right up. Battery is original to the truck with 62,****** miles. 

 

I am not opposed to taking truck to dealership although I know these types of issues can be difficult to trouble shoot. Any ideas of places to look?

My bet would be that the starter itself is your issue. Starter problems and battery cable problems from the battery down the starter are pretty common on the 2014-2018 trucks.

Did a bunch of research as truck would not start after several attempts. Replaced starter this afternoon and truck fired right up without issue. New starter seems to have corrected the issue for now.

I just had same thing happen last night and had my truck towed to dealership. They diagnosed same thing, bad starter. I will pick it up tomorrow and I'm hoping that it fixes the problem like yours did...

What did dealership charge to diagnose and replace?

Mine got covered under my GM Protection plan. But because there was a disagreement on labor charges, (authorized $170/hour but dealership charges $190/hour) I ended up paying $85. (I had another item repaired at same time under the plan so that explains the $85) Had I not had the GMPP, there was an initial $190 diagnosis charge listed upon dropoff but then that usually gets waived if repair is done.

 

Now if I hadn't had the GMPP, the cost would have been $342 for the starter and $342 for labor. It doesn't list the number of hours but using the $190/hour, looks like it was 1.8 hours for repair.

Quick Tip: if you suspect the starter, try "Tapping" it with a hammer or heavy metal object while someone turns the key (or if nobody is there you can bang it then try to start it), it will most likely start if it is the starter. sometime there's a "dead" spot in the armature windings and if the starter stops in that spot, it won't start, tapping it will "disturb" the armature and cause the starter to work.

Ughhhh! I forgot all about that. I'll bet if I had done that, I could have at least driven to my house Sunday night...

Update. So far so good. The intermediate starting issues seem to have been resolved with a new starter. Onward and upward!

      Tire psi

      By jgaudet99 · Posted

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Some Assembly is Required

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.

      Gas Prices

      We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Grumpy Bear · Posted

      Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money".

      Tire psi

      By Chuck FB · Posted

      I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back.
