Clean your battery terminals
Just a general FYI for anyone with a hard starting motor.
Quick background...
I bought the truck used last year and it's my first diesel. It always seemed to turn over "slow" and take a while to fire up... but I just assumed that was normal.
A couple of days ago, I went to turn the key and got strange clicking, guages going crazy, etc.
Anyway, final result was bad connections on the batteries.
I ended up taking each cable end apart, cleaning thoroughly and even replaced the bolts/nut on each one. Now, when I tighten the bolt it really grabs good on the battery posts.
Anyway, the truck seems to turn over much quicker and generally just seems "happier".
Hope this helps someone!

I would also like to add:
If your battery cables are involved with the corrosion leaching from your battery terminals, change out the cables.
I fought a chronic "short" issue I couldn't track down for years. I clean the cable ends and the cable wires where I saw some corrosion. I thought the cables were fine. turns out the corrosion on the cables created alot of resistance and the ohms test proved- bad cables.

Battery Testing
Been wanting share this for a while.
I remove the batteries from all my vehicles once a year to do a through cleaning of the battery and posts, cables then reinstall using something like Noalox to coat the the posts before connecting the cables.
