I picked up a 2007 2500 with the 5.9 with 135000km. I had the same truck but a mega cab for a number of years.

I am finding that the new truck turns over for a long time before it starts (4 or 5 sec.). This happens on every start cold or not. other than that I cant find anything wrong with this truck.

Could this be the start of a bigger issue? Thanks for the help.
