Well you treat your truck about like me...
If you've been particularly flatulent lately maybe you rattled something loose? 
I don't care who you are, that's funny right there

That no start theory the guys mentioned is a good guess, it will crank and crank and crank, did I mention crank..and will allow fuel to keep pouring.. Now I'm cracking up from those remarks made above, lol, O boy..

Try unplugging the PCM for a half a minute or so.....
I have run into STUPID problems when the KAM (keep alive memory) gets corrupt by some weird reason. When you take chips and programs out of and back into the truck as often as I do........you see some unconventional things happen. It happened to my truck again about a week ago.
It's worth the 2 minutes to try it.

Can you put a battery charger on the truck for a few hours before trying again? I know you said battery voltage is good, was that measurement at the battery or at the IDM?
Maybe put a jump start on it from a running vehicle. We know that out trucks tend to eat starters, Is the starter cable clean and tight at the starter? Is the starter spinning the engine faster than 100 RPM? Is the tach bouncing when trying to start? Just another thought, is the Cam position sensor good?

Yep, it's holding 11 volts while I cranked. Batteries are also pretty new Duralasts gold tops.

Nope, I don't have a no start tune loaded on the chip. Never have. I also pulled the chip out and tried cranking. And I had the chip out when I datalogged with AE while cranking.

off topic: I should have multi-quoted these post, would have saved me some time posting

Well, my fuel bowl is just over a year old. Plus I still have a WTS light that's functioning normally, so I don't have the typical symptoms of a bad fuel bowl heater. Plus it's firing fuel, so the fuel is there, I'm just completely stumped as to why it won't catch.

I did check EOT. Ambient temps were 80 degrees and rising (it was about noon when I tried to start my truck), and EOT was reading 70 degrees.

Subscribing to see it this works. It does seem like something electrical is jut not waking up since all the other parameters are in place and he's getting smoke while cranking.

Interesting. So unplugging the PCM is the way to clear it? Not hit the clear codes button on AE or similar, or just unhook the batteries?
