You might have found out the hard way that your GPR and/or glowplugs are not up to par. Usually 2-3 hours is long enough for the block heater to heat the coolant enough to help with the starting. My truck did exactly that a couple years ago in those kinds of temps and it was my GPR.

Perhaps if you can let it sit some more, then I would do so. I assume it's still cold out. I didn't mention in my last post that I got a bit anxious and I ended up killing my batteries trying to start my truck with the dying GPR.

GPR = glow plug relay, around $50 for a decent one (don't buy one from Ford). Do a search for Stancor... tons of reading. In the cold like that, you should give the glow plugs a couple cycles before cranking. They stay on longer than the light in your dash by the way! Turn the key on, wait 90 seconds, turn key off, repeat one or two more times. Now crank it, it should fire.
EDIT- you may also want to throw a charger on the batts to help it crank over.

GPR = Glow Plug Relay. Tells the glowplugs to turn on in cold weather. You can replace with OEM style or some members have upgraded to this:

Welcome to guzzle's Stancor GPR replacement Mod Web Page

I will be thinking of the upgrade the next time mine OEM replacement decides to die out again.

On edit: Chase's fingers are faster...

You also have a 2nd relay which is for your AIH ( air intake heater), that you realy don't need. You can swap your GPs to this one if you find that your GPR is shot.

Good point! Also a good opportunity to do the AIH delete if you haven't already.

Go hold a screwdriver across the 2 large posts on the GPR for 30 seconds, then try to start your truck (ignore the wait to start light). If it starts up that way, you need a new GPR.

Not to be a pain but; I'm sorry but I need a little more punctuation. With some periods & caps that end & start new sentences. Commas don't end a sentence. I have no idea what you are saying. Not trying to be a A$$, but just want to help.

Okay, it's just Jason's way of asking for some legibility in the post for us to help out. Enough on that.

I posted this in your other thread - read through this, good stuff:
