Hello
I have 1998 town car with 4.6 v8. Car worked well in summer but now it has stood almost 2 months i tried to start it and it shuts off after running few seconds. It gives p1260 engine disabled by pats.

But i noticed that instrument panel wont wake up until 30-60sec. If i wait that car will start normally. So i guess it is somehow related. But what would cause that kind of delay?

I have only one key and remote

Also could someone sell me pats off tune.

You can use Forscan to disable pats. You need a laptop and either a bluetooth or usb to obd2 adapter. The program download is free, but I believe you need the premium version of the software to do anything with pats. Luckily, you can get a 2 month trial of premium by joining the forscan forum, or you can just buy the premium code for a one-time payment of like $20usd

I programmed keys to a MKZ with Forscane a few years ago, I didnt have to pay anything. Did something change with them?
It used to be the code was good for x days because they dont want people using it for business purposes.
I wasn't aware forscan could disable PATS.

This seems odd though, a failed PATS should not let the engine turn over so I'm confused how you started it. But I'm not sure if that is how PATS worked in 1998. I know 2003 the engine isnt going to crank over as PATS wont energize the starter relay and I believe it may also cut spark?

You may have a bad ground that rusted while it was sitting.
When it shuts odd does the instrument panel go blank just before?

Sorry for my bad english. But yes i started to think maybe fault is in ground or in ignition switch.

When i turn ignition on, the instrument cluster is "off" no lights no messages, and when i turn to start it starts but stalls right away. But when i turn ignition to on position and wait about 60 seconds instrument cluster gets power and light up and then it will start and work normally.

I believe instrument cluster and pats module are powered or grounded by same relay/cable.

Yes, in my experience with pats it doesn't allow the car to start. It will allow the starter to run and the motor to turn over, but it will not start. I know this because I have a spare key that I have not programmed. It will turn the engine over with the starter but will not allow the car to start

actually it starts because when key is turned to ignition fuel pump runs and makes fuel pressure. But when car starts PATS disables fuel pump so it will run second or few until fuel pressure drops.

I remember getting so pissed off on my first build because I could not get the Pats to work after I did a engine build,I tried everything but it was locked up,so I bought a ARA3 ecu and never looked back.

I had a 1998 that I was trouble shooting. Long story short it needed a fuel pump and a key programmed. If PATS is disabling the car the engine won’t be able to start at all, what pats does on 1998s is limit fuel pressure. What did work however was wrapping the key in 2 layers of tinfoil and cranking it. An easy way to tell if PATS is actually disabling the car is to look at the flashing red light on top of the dashboard. IIRC a quick blink every 3 seconds or so means that the system is armed and on standby. Rapid blinking means that PATS isn’t detecting the key when you are attempting to start it; disabling the vehicle, and a solid light for about 3 seconds means it has the correct PATS signal and will allow the car to start. Hope this helps

I've never heard of PATS starting the car for a few seconds. Usually like other replies said it prevents it from starting at all.
