The nightmare is almost over. After wrestling with one of my other trucks I felt the "fight or flight" on the little green single cab 4wd know as Jalapeno, I would either have to start driving it or sell it.

I checked the PDC box as Black06 had suggested, partial disassembly showed the wires on the bottom and connectors looked like new.

I started checking other things, I pulled the knee panel and steel reinforcement from under the dash and started shaking wires up and down the steering column, whacking the ignition switch and the switch box farther down.

First the list of things I swapped or replaced or tested with no effect:

coil pack
cam synch assembly
crank sensor. Twice. since the problem code wise was pointing there.
drove around for weeks with fuel pressure monitor and fuel pump power feed monitor gauges hooked up.
reset DTC codes several times
soaked the motor underneath with water from a pressure washer in an attempt to reveal the short
traced wires from the crank sensor to the plug on the ECU, disconnected the ECU so I could get on the other side of the connector to check
bought extended license for forscan to see if I could unlock any hidden diagnostic procedures.
drove countless miles, truck stalling to the point my back hurt being so tense on the brake, gas and key at the same time. Just for testing, I have a daily driver but still intense.

Was starting to doubt myself as a mechanic and my ability to diagnose.

Next steps were going to be:
replace cam synch with an OEM ford product
swap ECU with another 3.0 auto for testing.
put passenger seat back in and drive around with my son watching the sensor voltages on forscan (might have revealed the problem or got me close)

I had done this before but I got under the hood and started shaking wires again (same session as under dash) but the motor was colder this time no fear of getting burnt.
When I put my hand on the cam synch plug and pulled it to the right, motor stalls. Tried it again, stalls. There is something wrong with the plug for the cam synch which lines up with every single problem this truck has had since I bought it.

Just wow finally a break.
