Cold start help?
After I get out of school my truck acts like it doesn't wanna start. I know these trucks hate the cold And should be plugged up but could it be a possibility my grid heater is going out of my truck or maybe a relay?? Just doesn't seem to be doing it's job. Thanks for response

you can always disconnect your grid heater and go straight to the battery not sure if its safe but I've done it before if you get sparks when you put the connections on, then it should be good if not, replace it. I used to have the same prob in hs with my Detroit diesel 7hrs in cold unplugged unhappy truck...

Maybe the 12v are different, im not a guru on them. But the grid heaters on the 24v have nothing to do with the cylinders themselves. It pre heats the air thats in the intake horn/mani. If the incoming air is less than 40° it will cycle. Regardless it should fire over ok even being close to 0°, unless theres some things that have been played with

No, that's true. Perhaps I should have said it heats the air for the combustion chambers, since my point was that that's where it needs to be warm. And before the engine has turned over four times while cranking it, all that toasty air from the horn is already long gone out the other side of the head, so...
