I have an 03 Cummins that is giving me some grief. When it is -3 C or 25ish degrees F my truck will not start. It basically starts at +3 and (38F) and will not start if it is colder. I do all my maintenence and try my best to keep on top of things. I have changed my air intake heater (grid heater) and just found out this morning that it is not that (unless the grid heater I bought off of ebay doesnt work right is there a way of testing the grid heater to tell if it is getting hot enough). I installed a recirculating block heater that really helps when it is plugged in but I dont want to have to plug in the truck when it is warmer than freezing. I never had to do this in the past either it used to still start when it was -25 c with out being plugged in. Please help with trouble shooting.


Thank you all in advance

do you add any type of anti fuel gel to your tank? where are you located at?

No I dont have anything like that. I am located in Calgary Alberta Canada. You think that would help even in the above freezing temps?
