When you are trying to start the engine are you giving it full fuel?

IF you still can not get the engine to fire you are left with the last two things.
You can give it a shot of starting fluid BUT you have to disconnect the intake heater
12 volt cable on top of the intake and disconnect the air intake hose from the CAC
making sure the area is clean.
This is a two person job one back at the engine another up front trying to start.
It is very important to make sure the 12 volts to the intake heater is disconnect as you will not want to be around that engine if the heater comes on and it has starting fluid in the intake.
If the engine still will not start you need to call a service man with a Cat computer and see what is not working. Two things come to mind both are not a easy test or fix but will show up on a ECM code with a computer.

A quick way to test the ignition switch is to turn the key to on then turn on the dash fan..If it works, chances are the switch is good...

With power to pin 70 of the ECM the key is working and that voltage source also connects to the tach.
If it still will not start we are down to testing the Heui pump (high pressure oil pump)
sensor and if working if it shows 870 psi while cranking. Also the throttle sensor connections at the drivers pedal all of which takes a cat test set.

As a rule but can be used if the air heating elements are disabled and used sparingly.

Never needed either at -30, fuel gelling is a bigger issue, if the Diesel needs Either or Heat (exception of pre cuppers) there is a compression issue...

Did you take it to a Cat shop?
A ECM going bad is rare and they are not coffee money to replace.
As a side note: You will need your engine ser # handy

I took it to a cat dealer. I'm thinking I fryed it when I was jumping batteries.
I was quoted a price of 2100 as this is the high torque ecm.

You can purchase rebuild ECM's far cheaper in the range of 600.00
and that includes flashing it for your engine.
Some companies just rebuild yours if they do not have one sitting
in inventory already.
