Bought this new 2500HD 6.0L gas a month ago. About a week after taking it home, we began having difficulty starting it.Rolls over a few times, coughs a bit, rolls again, and starts. Feels like a fuel issue. Either no fuel and no ignition, or no spark and a bit of flooding before the spark fires -- that cough makes me think now it might be flooding - where at first I thought moisture as it does it more in wet/chill days, or high humidity. Not positive of any of this as it's only got 2000 miles on it. Does no do it every time - more like occasionally.We're traveling from Florida to California hauling the TC ... we're in San Antonio and it's at the Chevy dealer. Of course, won't do it now, as it's pretty sporadic. Chevy dealer says, "no code, so we don't know."First, just because there is "no code" doesn't mean there is no problem. SO, what happens when these 'code mechanics' actually need to trouble-shoot? Well, I have no clue, but spending $40K plus on our new trucks that won't start correctly and the "code reader" says everything is hunky-dory ain't gonna cut it for long.The dealer gives me a loaner -- and it rolled and coughed before it would start too. Very weird situation, 2000 miles from home with this issue. Bummer ...Gotta say tho, aside from this issue, truck runs great after it starts - and hauls like it should. Good on the back-roads and the highways. Just purrs right along ...But it concerns me a lot that it starts hard - and in fact, I drove about six trucks before I found one that 'sounded right' to my ear.And several had acceleration issues during the "test drive" ... and this one did not - at least not perceivable at the beginning.SO, any of you all driving this 2015 truck (or the 2014) gasser that's giving you this 'start' problem? And did anyone find out why?Will take it to the next GM level if the dealer has no answer beyond the "no code" statement. It's not a huge issue yet, as it always rolls over and eventually starts - but it could be and it certainly needs attention. We're heading into the western national parks, and that is definitely not a good place to have 'truck trouble'...

Turn the key to "ON" listen for a click within about 3-5 seconds. No click could mean that the fuel pump relay is not activating to pressurize the system for starting.

No click could mean that the fuel pump relay is not activating to pressurize the system for starting.The new GMs don't do this. Instead of being a having a fuel return and pressure regulator to dump the excess fuel, the new GMs use a variable-flow fuel which is Pulse-Width modulated by the PCM. It only needs a fraction of a second to build pressure, and immediately slows to maintain that pressure.

I would start with the very basics... Are the battery terminals tight? Have they been cleaned? Even a new truck has probably sat for a couple months at some point, and that is all that is needed for some corrosion or oxidation within those side-termals.Low voltage during cranking can cause the PCM to drop out, which causes it to not fire-off, and it won't store codes because it doesn't know anything is wrong since it is shutting off.

Have to say you will need to live with it until you get back to your home dealer, unless you can get it to act up when they are right there. Is it doing it only on the first start of the day? If so leave it over night and go back in the morning. Have the service manager and mechanic at the vehicle with their scan tool plugged in to see if it will act up. We had a guy at the plant going through the same thing and the dealership hooked the scanner to the vehicle and told him to come back after it acted up. The scan tool can capture the condition and show them what is going on. This maybe the only way to get it repaired. Don

Should'a bought a Ford, then you wouldn't have THIS problem :BJust kidding.... Seeing as how you had others that do it, then maybe this is Chevy's new standard "starting sound"?? I'd say as long as it is starting every time then don't worry about it. The environment around you is probably playing a role in causing this also( like you had said cold and damp )Good luck with the new truck!

WHAT? What's this about buying a tailgate? I removed it so I can haul my truck camper ... the tailgate is in my garage?

And the book does not explain removing the camera connector in an understandable way if you actually attempt to DO it, which I did. And, yes, it is a true PITA to get your fingers in there -- the spare tire is in the way, and it means you have to crawl under the truck, figure out which one it is, and then pull it sideways with no leverage, and I can't fine a "Cap" anywhere near it. There are THREE plugs there sitting together and you can't tell which one it is - three separate wire leads -- for you all suggesting me read the manual, Just read it - and then jump under your truck and do ONLY what the manual says, nothing else - and see how easy it is, well, it ain't. The 2015 is different then earlier models, I'd guess, just from reading this thread. IT says nothing about "behind the license plate" - where in fact it is located, sorta, but you can't reach it because the spare tire obstructs it.

Ask me who wants to crawl under the truck every time you remove the tailgate - at least those of us who do it often - Like every time we camp.

LOL yep I forgot about that "man step" on the Fords. I agree with you the new gates are going to cost an arm and a leg to replace. The cost of the paint for these new vehicles is out of this world, then add in the camera, wiring and hardware. I can see $5,000 or more to have a tailgate replaced. BTW do all the new gates have locks that are controlled with the key fob and or door lock systems?

Don

Sorry but I was not in sales my last six yrs at dealership and lost track of my product knowledge..
So I don't know about locking system..
If they have power locks also add another $200 or so to price I imagine..
Crazy..:h

Just to put it in perspective. That is up to 10% or so of the value of a well equipped truck today. Just in the tailgate. Crazy.

Seriously, just hope no body else removes your tailgate cause with all the stuff that can be in them in them the replacement price is crazy.

Go back about 10 years and predict that in about 2013 a tailgate for a pickup truck could cost over $2000 and they would think you went off the deep end.

Well one for my 2004 Ram costs $804 just for the gate! By time you add in the other parts that may be needed, along with paint and labor it sky rocks up to over $2,800 :E So you 2013 gate would more likely end up costing you around $5,000.

Don

OK Don..
A Ford could be worse then if it has the step and the camera and the fancy trim I suppose?

Go back 10 years and predict to your buddies that a pickup tailgate could cost $5000 in 2014 and they will have you declared insane.

Just like the price is eh? INSANE :S

It's very, very difficult to get to it, and believe it's a pretty dumb engineering fault to put it there if you need to get to it. Major hassle -- major hassle, I'll say it twice so you get it ...

Ford got it right in this department, they include a dummy plug in the glovebox to install when the tailgate is off. And the plug is easy to disconnect when removing the gate.

I know my '11 has the plug cover and is easy to get to behind the license plate, but he has disconnected his and he says it is NOT the same as my '11, so I would say he does know what is actually there and how easy it is to do.....

The way these fellow GM owners are jumping on you, you'd almost think you were driving a Ford.. :W :W :W :W :W

As far as fuel being a problem...quite possible. Currently in our neck of the woods, refiners are gearing up for our summer blends. If you get some of the winter blend(or vice-versa)and the temps are opposite for the fuel blend you have in your tank...there "may" be some sort of running/starting problems. We used to see this alot in carb and early fuel injected vehicles. Does'nt seem to be as much anymore but still possible.
