It's very likely your fuel is gelled up. Here in the northern states our winter blend fuel has additives in it to prevent against gelling in freezing temps. The cold temps were just as much of a surprise to the oil companies as it was to you. Under normal conditions your fuel would never need these agents as you'll rarely ever need them.

In the instance you went on a road trip up north in the winter, you would get fuel along the way that contained an additive to prevent this.

Get some Diesel 911, let it do it's thing and you'll be just fine. Your fuel filter may be gelled up as well since you've been cranking on it, but that should clear up once things warm up over the week.

I had the same issue! Mine did crank and started for a couple of seconds. I raised the hood let the sun warm it up. Got an indication I had water in my fuel filter. When it started I drove around a bit and moved one of my benz’s outside and the Jeep in. All is good now. I do NOT have the block heater cable for my Jeep.
Water in fuel - was it a false alarm?

I understand ALL our Eco Diesels came equipped with block heaters...but ONLY IF you ordered a block heater on your build sheet, it came with a cord. Supposedly you can go to the dealer and purchase the cord and connect it to the already installed heater...It's also suppose to be a MoFo to get to though.

Search around here, there was a thread about that a while back.

It’s wanting to turn over but won’t fire up. No block heater. Battery has juice from What I can tell. It was in this colder weather all night.
I’d get a block heater ASAP if you live in those temps. Cold starting a diesel is the worst thing for the internals of the motor.

Good luck getting her to start by the way. Once you do; do yourself a favor and grab that Mopar block heater cord right away

Thanks. Once in a lifetime storm here. I’m gonna leave it parked for now. Can’t do anything until temps rise, hopefully tomorrow or Saturday. Average low in north tx this time of year is 30-40 ish. Not -2

If you have electric power, I recommend attaching a battery charger/tender. I am not sure how it all works when cold, but the system may be using the battery to do things like keeping the DEF line from freezing. (DEF freezes below 12F.)

Not sure, could have been some condensation. Once I got it running it was fine. I did run into a guy that had some diesel additive and put it in my fuel tank. He was driving a Chevy dually and after he asked if I was sure I had a diesel he offered it to me.

That made me smile. Does he think that you just have a confused look on your face when you are looking at the fuel pumps?

^ I agree with what you’re saying that’s why I own a ranch in CA but my legal residence is my house in Tampa. I also own a cabin on acreage in Wyoming though so I’m following this closely

When I was living in the high country of Colorado people used a very cheap trick to keep the engine warm. They put an old fashioned incandescent light bulb into the engine compartment. It might be tough getting the old style of light bulbs, especially in California. But a single 100 watt bulb is enough to keep the battery and engine from freezing.

I get all kinds of looks at the diesel pump at the local truck stop, but when I pull up and put DPF in they get really confused.

I have had a few tell me “you know these are diesel pumps right?” And I say yep, it is cheaper than 91 octane!” Then drive away!
