PCM programming shouldn't have much to do with the PATS not working, but should certainly be an update for it if it's never had it. Keep in mind, if it went in for warranty work or recall work, they will update it automatically sometimes...
The PCM communicates with the PATS module to find out if a correctly coded key is in the ignition. If the right key is there, the PCM will allow the vehicle to start. If it isn't, the PCM will not allow the vehicle to start.
The most likely problem is that Swamps put the wrong program into your PCM. Although if they put a regular non-PATS program in there, you would think it would go ahead and start.
I wonder if it's possible for Swamps to get the program off of the original PCM and dump it into your new one.
I don't think it will work to just program the PCM to non-pats. If the Pats module can't communicate with the PCM, it won't start. I think you are right on that the programming is the issue though...

OK. Last Year my FICM failed. I replaced it with one from Swamp's. Truck ran great for 8 months. Drove to work one day, crank no start.
Diagnosed PCM as a failure by codes. Bought new PCM from Ford, sent it and FICM to Swamps for programming.
Truck still crank no start. Drove myself insane checking things. Removed FICM, sent to Swamps to confirm FICM is good, benchtested there as well as vehicle tested, both tests passed.
Reinstall FICM, theft light rapidly flashing. Ford IDS tool could not communicate with PATS. Gave the F up and had truck towed to dealer with my tail between my legs.
Dealership diagnoses bad PATS, I meant to say 1/2/2012, dealer installs new PATS, did not fix problem.
Dealer now says FICM is over voltage and is bad. This is the 58V FICM from swamps, explain to dealer, have Dave from Swamps call dealer to explain. Dealer wants to replace FICM 800 + hour labor.
Tomorrow, I'm removing the FICM from the truck to send to SWAMPS to verifiy FICM is good.
with out doing a lot of digging I think the pcm contains pats in this truck. if it worked prior to the reflash then I would call the folks that reflashed it.

It actually does work to put a non PATS PCM in where there shld be PATS I've got a prob with my 97 Expedition and it runs with a non PATS PCM but still will not start with the original PCM. Mine isn't communicating as well still trying to track down the problem I guess it would depend on what type of PATS the truck has as well

I know that this is a very old thread. Are you also having a problem beyond the non-Pats Vs the Pats PCMs?
You may also want to check all the pins.And if any modules have been
removed and replaced take a very close look at both pins and sockets.
Your looking for a displaced connector at the PCM or VSM (Vehicle Security Module).
I find it interesting that so many people hate the PATS system. I would be happy
to have it in my truck.
But as far as the basic things go I would need the right programed PCM,VSM,cluster,Pats antenna and some harness work.
That is all dependent on if it would even work and the software would pay fair. The reason for the cluster would be for the lamp.
