update after pulling battery cables to try and reset and pulling fuses I now have lights and power to seats and windows but car just clicks when trying to start. Don't suspect battery because all interior lights are bright but still tried jumping with another car. All this does is send it back into anti- theft mode and I have to pull fuse to reset.

Try your spare key. You may be having a key issue. The antitheft system has to recognize your key. If neither key works, the problem lies deeper and its off to the Ford dealer. They use a "new generation star tester" to troubleshoot it. I do not know of any general consumer ways to diagnose the system. Following is some general stuff on the system which may help a little.
There is The Passive Anti-theft System (PATS) contains the following components:
theft indicator
encoded ignition key
transceiver module
PATS control module (located behind the passenger side air bag module)
Powertrain Control Module (PCM)
Standard Corporate Protocol (SCP) communication network
The Passive Anti-theft System (PATS) uses radio frequency identification technology to deter a driveaway theft. Passive means that it does not require any activity from the user. This system is known as SecuriLock(R) in North America, Safeguard(R) in the U.K., and PATS in continental Europe. This information can be found in customer literature such as the Owners Guide.
The PATS uses a specially-encoded ignition key. Each encoded ignition key contains a permanently installed electronic device called a transponder. Each transponder contains a unique electronic identification code out of over 72 million billion combinations.
Each encoded ignition key must be programmed into a vehicle's PATS module before it can be used to start the engine. There are special diagnostic repair procedures outlined in this manual that must be performed if the encoded ignition keys need to be replaced.
The encoded key is larger than a traditional ignition key. The key does not require batteries and should last the life of the vehicle.
The transceiver module communicates with the encoded ignition key. This module is located behind the steering column shroud, and contains an antenna connected to a small electronics module. During each vehicle start sequence, the transceiver module reads the encoded ignition key identification code and sends the data to the PATS module.
The control functions are contained in the PATS module. This module performs all of the PATS functions such as receiving the identification code from the encoded ignition key and controlling engine enable. The PATS module initiates the key interrogation sequence when the vehicle ignition switch is turned to RUN or START.
PATS uses the Powertrain Control Module (PCM) to enable or disable the engine. The PATS module communicates with the PCM over the SCP communication network in order to enable engine operation. The PATS module and the PCM use sophisticated messages in order to prevent a theft. The PATS and the PCM share security data when first installed together, making them a matched pair. After this security data sharing, these modules will not function in other vehicles. The PCM shared security ID is remembered even if the battery is disconnected. The PATS module also stores the vehicle's key identification code, even if the battery is disconnected. There are special diagnostic repair procedures outlined in this workshop manual that may be carried out if either the PATS module or the PCM needs replacement.
All the elements of PATS must be functional before the engine is allowed to start. If any of the components are not working correctly, the vehicle will not start.
PATS uses a visual theft indicator. This indicator will prove out for three seconds when the ignition switch is turned to RUN or START under normal operation. If there is a PATS problem, this indicator will either flash rapidly or glow steadily when the ignition switch is turned to RUN or START. PATS also "blips" the theft indicator every two seconds at ignition OFF to act as a visual theft deterrent.
PATS differs from the perimeter anti-theft system in that PATS enables and disables the engine from starting. If equipped, the perimeter anti-theft system protects the perimeter of the vehicle (doors, hood and trunk) and sounds an alarm.
The PATS is not compatible with aftermarket remote start systems, which allow the vehicle to be started from outside the vehicle. These systems may reduce the vehicle security level, and also may cause no-start is sues. Remote start systems must be removed before investigation of PATS-related No Start issues.
The passive vehicle protection system will be activated and will disable the vehicle from starting if there is a:
damaged encoded key.
unprogrammed key.
non-encoded key (key has no electronics).
wiring concern.
transceiver concern.
PCM concern.
module communications network concern.

Well, since both your keys fail to start the car, and the antitheft is not turning off when you put either key in the ignition, I would say you are having a problem with the antitheft.
Could be the transceiver that talks to the keys has failed, but that is just a guess.
Nevertheless, the antitheft part of the system is working. Since it has not recognized the keys, it assumes you are trying to steal the car, and everything is shut down.
Ford deliberately does not provide work arounds to this. Car thieves would figure it out.
You could reprogramming the keys, but I really don't think it would work. I can't think of anything else but a tow to the dealer. Good luck!

I haven't had to try this, but I read about it in a Superchips manual:
1. Remove the ground cable from the battery post. Touch the ground cable to the positive battery post for 15 seconds and then leave the ground cable off the battery for a period of 15 minutes to allow the vehicle DTC codes and Theft codes to clear.
2. Re-attach the ground cable to the battery and start the vehicle as you normally would.
Let me know if it works.
