Wont go when cold

Colorado fuel should be climatized to the temps you are providing....especially if this is happening with ambient temps in the 20's. You buy fuel regularly, correct? In other words You don't have fuel sitting from summer time....if so then it could be an issue.

 

[Lordsman]

Yes buy fuel regularly, just filled it up.
I spoke to dealer, they ran the VIN, and this update or TSB has not been done. I gave them the Star Case# that Sag2 provided. It will be $118 for them to update the Body Control Module (BCM). Made the appointment. I can't get in till Jan 20th., bummer...
I'm out of town but will do my own check to make sure the fuel heater isn't getting voltage below 30 degree's when I get back to the truck.

Tuesday, thank you for the link. Looks to me like that is the problem. Temperature was down to -9 last week and daily been at highest daily in the 20's.
Bought the truck in the summer never had an issue. It started happening when we took in to Yellowstone in early September, it got cold and the problem began. Previous owner probably knew about it and didn't tell me?!
Thanks JR I was wrong in thinking it was a regen issue.
I'll get the info together and contact the dealer near me for a flash/update repair. Need my truck!

Tell them to check all modules on the Truck for missing updates! Some people refuse them and the Truck has problems down the road. The updates are there for a reason and not just fun, today's highly computerized vehicles need them, they aren't finished from factory.

 

[Lordsman]

Makes sense. I'll have them update it properly.
Thank you all!

Sometimes to be sure one is fixing the actual problem, and this is a very good point of what fuel should be, an inspection is in order.

As the linked thread mentioned: when the truck has no power, pull over, and spin off the rear fuel filter to look for fuel gelling. A fuel pressure gauge would be another way to tell. (Not something I would do in the cold on the side of the road so a fuel pressure gauge is what I would install in a warm garage.)

I have gone through so many lift pumps on things: intermittent failure when cold would be "normal" for me.

Absolutely ask for all updates and if the dealer will do it as a "package deal" to update everything for one price.

So has this problem been solved in my new 2022 or is it something I should be concerned about. I to think running anti gel is very necessary . For me mostly year round in Alaska. Some say it’s not needed but that’s not true. Gelled fuel really sucks

We are talking about an almost ten year old vehicle Terry, no you don't need to be concerned about that old stuff.
But keep in mind to remind your Tech to check for updates Everytime you turn in the Vehicle - as some do not do them by them self.

 

[Turbo Terry]

These fuel stations say they have winter fuel but some of the in between the really cold and hot states don’t really know the diesel fuel game. Here in Alaska it’s very important. And never get to the bottom of your tank I think that’s a terrible mistake asking for trouble

 

[Turbo Terry]

Good idea. Check up dates

I'm out of town but will do my own check to make sure the fuel heater isn't getting voltage below 30 degree's when I get back to the truck.

It doesn’t have to be under 30°F to verify if that connector at the rear housing is getting voltage......

 

[Lordsman]

Got it. Looks like it's actuated at 32 degree's and enabled till 64 degree ambient then off. There's a lot of info out on this.
Hmm.. I noticed when I changed fuel filters before our trip to Yellowstone that inside the engine filter canister there was some yellowish crusty junk on the bottom. I loosened the junk up, cleaned it out, and then installed new filter. Evidence of jelled fuel?
From what I'm reading I'll need to do the filters again once the heater is enabled.

 

[Ozymandias]

No, gelled fuel leaves no residue as it is only paraffin turning into wax, as soon as it warms up it turns back into liquid form.

Did the filter look like it was contaminated also? If there was a lot of material in the housing I would pull the filter and look again. Shouldn't be anything in there as the primary should collect everything visible to the naked eye. Fuel contamination including algae sounds possible and would definitely give the driveability issues you are describing. Once algae hits a tank it is extremely difficult to get rid of. Simply putting fresh fuel in won't eliminate it.

 

[Turbo Terry]

They make a treatment for algae. I have used it a time or two

 

[Ozymandias]

Me too, had some algae in my stovetops diesel tank.

 

[Lordsman]

The filter looked ok. I'll get the heater turned on then go from there. Appreciate all the input!

 

[Tuesdak]

Drain some fuel into a clear jar from your main filter. Does it still have a bunch of that stuff come out in the jar?

 

[gsbrockman]

From what I'm reading I'll need to do the filters again once the heater is enabled.

Have you checked voltage at the connector yet?

 

[Lordsman]

I drained fuel a while back and it looked pretty good.
VIN check for service done to truck by dealer shows heater is not enabled. I'll check it when I get home to verify.
Just found out about the heater issue for 2013-14 trucks. Sure seems to make sense as I had no problems till weather got cold.

 

[Ozymandias]

Shows that there were no updates done in the past.
Good to do them now.
