no start no WTS

So truck wouldn't start on Tuesday. In michigan till march but need the truck on arrival.

Put key in ignition as I turned the key the WTS light came on for a sec then all power to the truck was lost.

I took battery cables off and cleaned them. No luck.

Replaced fuse #22, still not recieving a WTS.

^ I found that while on vacation.
I made it down to fuse #22 is good, now to check the pcm for power.

How do I go about checking that red wire?

Did you disconnect the fuel filter heater before replacing fuse #22?

Are you sure that connector isn't touching something that's shorting to ground?

Are you by any chance using that circuit for the e-fuel pump? If so, I would disconnect it, and see if at least that turns on the WTS light. Other thing I would try is disconnecting the red/green wire from the GP relay, since that's also on the PCM power circuit. Again, just to see if that gets the WTS light on.

E fuel is taking power from starter relay.

I will try the gp relay. I put a oem gpr in back in October. But I will check it out as well.

Does your truck still crank over when when the dash goes dead. What about by jumping the starter relay. It sounds like a bad connection to me

Negative, the truck does not crank.

It seems like a bad connection somewhere.

I had a similar issue in December. I replaced the starter relay with a parts store version. The problem was corrected till this past week. Now the same issues have risen. So I went to ford and purchased a OEM version. Anyways the OEM relay did not change anything.

No cranking, no WTS

Grounds are clean, battery terminals are clean, fuse 22# is good.

Can a burned 3rd brake light cause these symptoms?
(I would of checked before I left but my camper shell is in the way.)

That changes the game completely. Cranking and running the engine are on two completely separate circuits, and the only thing in common between them is the ignition switch (and, of course, main battery connection). Your problem is either way "upstream" with a maxifuse that energizes the ignition switch, or the switch itself, or as said above, a major battery/ground connection.

No, completely unrelated.

Do ANY accessories work? Headlights, brake lights, parking lights, hazard flashers? What about key-on accessories such as the HVAC blower and turn signals?

After the truck has sat randomly some times when I open the door the dome light will come on, and then it shuts off quick. So the truck has power randomly but gets interrupted and just turns off with in a a second. The first time this happened last Sunday, the keys where in the ignition WTS came on for a second then all power was lost. The truck will act completely dead

Negative at times the dome light will work when the door is opened. but power is quickly lost before I can even try activating any accessories
