Cold weather disappointment and frustration!

It is 9 degrees here in Denver. I went out to start the truck and it will catch, fire off, stumble, the starter tries to re-engage and then it shuts down. I tried cycling the glow plugs a few times but always the same.

I get out and start looking for the heater plug-in which I have never used on this truck or the last 8 or 9 Powerstrokes and cannot find it. I call On Star, ask for roadside assistance and speak to someone who I can hardly understand. After about 5 minutes of trying to explain “I need to know where the block heater plug is on the front of my truck” I give up and call a local dealer.

The dealer explains where it is at so I change, get the step ladder out, blanket the fender and finally see where I think it is ty wrapped underneath to another bundle of cables. It takes me nearly 20 minutes to get it loose enough to slide the side cutters under it because there is not enough room to just come in 90 degrees to cut it free.

I have never had to use a block heater in Denver to this date and then when I need to use it, it is buried under underneath the back of the engine instead of out front where I can easily get to it. I was told that I always have to open the hood lay the end of the plug close to the engine in order to use the block heater. There is evidently some type of sensor at the end of the plug that needs to be kept next to the engine. REALLY!! Why is the block heater engine temp sensor not part of the engine and the plug-in up at the front bumper like all the others I have owned.

Had to ask wife for her car keys as she stood there laughing about my new 50k truck not starting.

Well it is plugged in and if it does not start in a few hours they can come tow it in.

9 damn its warmer there I am in the foothills and it was 2 when I left this morning, I haven't had to use the block heater on my 12 yet, it fired right up this morning. Took a long time for the heater to warm up but other than that it fired right up and drove perfect.

Definitely shouldn't need your block heater at that temperature for start-up purposes.

I would take it into the dealership you bought it from...definitely should start at that temp without having to be plugged in. Did you happen to be extremely low on fuel? I was thinking maybe the fuel gelled up.

I never use block heater and I live in -20 -30plus Celsius! Trust me its not the cold....use remote start with never ever plugging in and starts like a charm!

Sounds more like a fuel issue. Maybe you fuel filter is loose or seal is not on properly. Did you try priming it? maybe you have low fuel? Never let the tank sit overnight with less then half in it. As soon as it gets cold my rules are use the half tanks as the empty gauge for my diesel or gas engine. Condensation leads to messy situations. It's fine if your on a road trip but if your going to park it overnight fill her up!

I plug my truck in at night and its only getting into the 20s here. Reason being, my batteries are getting weak. So they are having a hard time with the cold and start ups take a bit more out of them. Until I decide to replace them, its no big deal for me to plug it in. Doesn't hurt anything and has kept me from having to jump start the truck.

Im with this guy^^^ Never below half and have only had to plug in my truck when it was -34F and it started after being plugged in for 30 mins....If they don't mix a winter diesel down there at the pumps you should run an anti-gel each tank...problem has to be fuel its not the truck

This is my first diesel.....but if you don't need the block heater at 9 degrees to start this beast of a truck, when in the hell do you need the block heater? LOL

We had 12 inches of snow here a few weeks back and temps in the low 20's. My baby was outside (long story) and when I started her up, she turned over but slow and seemed labored......I think I might have had a problem if the batteries weren't new.

Even if it's not "needed" at that them, seems like it woudl help with oil flow at startup.

The 2011+ diesels were specifically designed to start in extremely cold climates without having to plug them in. It was 20 degrees F here this morning with a wind chill of ~10 degrees. My truck started right up without being plugged in.
