Another PATS problem... I think

Another PATS problem... I think
2000 F150 approx 190K rusty but trusty... until now.
Insert key, turn and getting the quickly flashing antitheft light followed by code 16
connect scan tool, it will power up but will only show a link error
what I have done:
-pulled, cleaned and reinstalled cabin fuse box
-swapped PCM and fuel pump relay in engine fuse box-no change
-started tracing wires. I am slightly color blind which can make this a challenge.
-checked all fuses in both boxes
Questions I have
-should there be power at pin 30 of the pcm relay?
-I am thinking the problem is the PCM is bad/not getting power it is fairly buried behind the battery, how do people check the pins with it in place?
-Is there a step by step troubleshooting or is pats a dealership only repair when it is code 16?
problems I have are
-I only have one key.
-the truck is not worth having towed to the dealership to diagnose
any thoughts or ideas would be appreciated.
Thanks!
Steve

Did not load test the battery, but it cranks the car at normal speed. I could try a battery out of one of my other cars that I know is good. I will update that in the morning.

Should there be power at pin 30 of the PCM relay? Key on power?
Do you have the digital odometer? if so, what is it's state when the key is turned from OFF to RUN?
Does the check engine light come on when the key is turned from OFF to RUN?

Truck is running again! pulled the under hood fuse box, Found a bunch of green-never a good sign. Cleaned it up, replaced a few broken wires (including the one going to pin 30 on the PCM relay) and the truck is running again. It is warming up as we talk. and I get to reassemble half of the dash. Very much appreciate the help. Let me know if anyone needs anything in upstate NY and I will try to help.
