Easy cold start...hard hot

Its been getting into the mid 20's at night recently and in the morning on my way to work my truck fires up like a wet dream. When I get out of work its a good 75 and my truck will roll over for what I think is a little to long for a nice warm day. Not a big deal just kind of has been blowing my mind because it was a pain in the A#$ last winter.

Great mountain truck!

Make sure your glow plug system is working properly. Also make sure the batteries are good. That's about all you can do unless you replace the batteries with new high cca ones and replace the glow plug relay with a stancor. I did that and I haven't plugged my truck in in 3-4 years.

HEUI motors ALWAYS crank longer. Takes time to build oil pressure.

I understand that fully. It just seems like mine takes longer than normal.

That seems about normal.

If you want it to crank faster, get bigger batteries. my Diehard platinums crank my truck over FAST and it starts Fast

A heavy duty starter (forget the damn name...) will start that thing very quickly too. Also, oil selection helps start the truck faster.
