I bought a 2000 ford explorer 4.0 xlt around a year ago... It needed a starter and fuel pump. After installing the starter and fuel pump it ran and drove fine for around 3 months until one day I turned the car off and when I went to start the vehicle again it wouldn't turn over.

So like a dumbass I assumed the fuel pump broke, because the gas tank itself was rotted and I bought another new fuel pump plus a gas tank. After installing those, the vehicle still wouldn't turn over. I checked the fuel pump by putting a paper clip into the relay and heard audible noise coming from the pump. And I checked the fuel rails and those are getting fuel.

Then I realized that there was a blinking theft light on the dash and googled and seen that it was in PATS theft mode. I just bought an OBD2 to usb and downloaded the trial version of forscan on my laptop.

I only have one key, the key fits in the ignition and will turn the accessories like the stereo and lights on and it will even turn the starter over but since its in PATS theft mode it won't turn the injectors thus starting the vehicle.

I believe that the PCM is bad. I get a 1:6 theft code on my dash which is a communication issue between the PCM and PATS theft. I have tried everything that I can google for the most part. I am looking for some help please

I have tried everything that I can google for the most part. Any specifics on this would be beneficial.

Before going straight to the PCM, I'd rule out any issues with the PATS module itself.

I attached some images of a pinpoint test for symptoms you listed which you may not have been able to find on google.

If you need me to pull up anything linked or referenced, just let me know and I'll get back to you when I can.
