Outside temp dropped tremendously overnight

So the temp here dropped over 30 degrees overnight and is now close to about freezing and all I'm getting is a crank but no start and alot of thick white smoke out the exhaust anyone have any suggestions? I'm recharging both batteries now even tho they are both under 6 months old and once they recharge I'm going to try it again..... I cycled the key numerous times first but they still didn't help it kicked off twice but didn't actually start unfortunately..... I'll try and get a video after the batteries recharge and I try again to start it

You don't need to cycle the key...plug the truck in for 45 minutes and it should fire up...

Most likely a bad GP relay. If you need the truck ASAP just use a screw driver and touch the two big terminals on the GPR for about 10 seconds and try to start it.

Define cycling the key...
Helps to know what truck you have.there are differences in the four years listed.
There are differences between federal and west coast truck.

The WTS in not the glow plugs.

The glow plugs will stay on up to 90 seconds depending on conditions.
When cold.... cycle key to run, wait about 30 to 90 seconds... roll key to start truck.

yesterday topped out at about 42-45 IIRC at about 10 am, and it started downhill from there and has not recovered yet

IF, I were going to start mine, I would plug the block heater in for about 4 hours.

It was 12 degrees here this morning. Fired right up in less than a second after waiting about 15 seconds with the key on before turning it to crank it in the parking lot after it was sitting all night at the mill during my nightshift.

I say that so you understand that plugging it in like people are talking about isn't required to start up when it's at freezing. I know mine will start at negative 21 on just glow plugs in the parking lot. Plugging it in just means your heater will work faster at thawing you or your windshield out.

Like they mentioned, glow plugs. At about 50⁰ you'll need glow plugs, lower temps than that and you'll have hard starts with longer cranks if the plugs aren't working properly. If you have the relay vs the glow plug module jump the large terminals for 10 seconds with a stout screw driver then run around and crank it. If it fires up replace the relay. If it doesn't you'll have some more in depth work to do

If you are in a just plug it in mentality you can put it on a timer, or even a smart plug. It only takes roughly 90 minutes to get it about as warm as it'll get, so set it to come on an hour before your alarm clock and it'll be ready when you come out to it. If it's a smart plug you can turn it on or off with Alexa or your phone. It doesn't cycle itself on and off, it's a full time current draw. So don't be surprised if you plug it in when you get home Friday afternoon and don't go anywhere until Monday morning when your electric bill is higher. That's nine 100watt incandescent light bulbs running non-stop

Its like running a small microwave oven all night. Your electric bill wont appreciate it. It does help it fire off and get you going quicker when it gets down in the nasty cold in the teens or twenties. If knew I had to get out there and fire it up at o'dark thirty when it's 12 degrees out to be somewhere, I'd use it though.

​​​​Not if -21 is the high and your truck's cold soaked. Even plugged in it will be pissed at you for waking it up.

That was at 5:30 in the morning leaving the parking lot from work after my 12 hr shift. It started but it sounded angry until right before it went into high idle and I started scraping ice

It's that Angry Sound that I avoid.

I won't start it in the super cold, unless I have to, like being stranded and it is the only thing with wheels that will roll.... that did happen up in Utah to me once....

it was 25*F with the new starter motor on it, and fresh 5w40 full synthetic.
I waited until the Battery volts started to climb back uphill, and it cranked up in about 5 or 6 seconds.... that was in March IIRC, so been a while.

it wasn't real happy, but it never faltered.

that's for sure. Cold weather started killing my batteries in November with starts getting more and more iffy as temps dropped. Then this week it was dead as a doornail. Christmas gift cards make great battery boosters. Got two new ones from Oreillys and spent two hours changing the batteries in 13 degree weather with 15-20mph wind.
Would have been much faster but one battery mount bolt grew legs and jumped out of the tray, down past the washer fluid tank and hid in a corner under there until I dug it all out to get to him.
Froze so bad I had hot milk instead of ice cream for dessert.
