I am hoping to pick some ones brain I pulled my truck out of storage about 3 weeks ago and put a total of 20 miles on the truck since then. I used the truck yesterday and everything was fine with it. I went to use it today and I have nothing. All the dash lights, head lights, turn, etc. but no start. I tried cost starting and nothing jumped starter it spins but no start. I traced wirs from ignition and clutch pedal to the fuse box under the hood and over to the pcm (wire25) all have 12 volts. I cant find power anywere else and my local Ford hasnt seen hardly any 6.4s so they were no good. Any one got a couple pointers I can try to get this thing going?

Sounds like your TCM or PCM may be corrupted.
Here is a procedure posted by H&S that may help.
"Try and read DTCs with your tuner. If you can communicate with the PCM, then the TCM is likely the culprit.
You can also test for functionality of the PCM by:
Turn key to RUN
Find the Brown wire with light green tracer behind the passenger battery
Unplug the black connection on that wire, connect the male side of that connection to +12V
The truck will crank, and should fire if the PCM is ok.
I have seen a couple of TCMs go down lately, it seems they are quite volatile to software corruption. The nice thing about them is that they don't require any vehicle setup to replace them. Simply find a new or used TCM and toss it on your truck. But, depending on how your tuning device works, you may need to get some new tunes written.
If the truck cranks but does not start, then the PCM will need to be recovered. I have yet to see a fully failed PCM that we couldn't recover. I have had to ship a few to our shop for some "custom" recovery work, but we have always been able to get them to talk again."
