Step 1
Is there a fuel cutoff switch on this model? Check Switch
Check PCM relay
Step 2
Reset instructions PATS
• This has reset instructions when you get to the point where she turns over but won't start.... re-syncing the pats key anti theft instructions....
If it’s the PATS system......key out of ignition....put key in and turn on but do not start........look at theft light....should be blinking fast.....wait 30 to 45 seconds or until it starts to blink slow or goes out.......turn the key off and remove it from the ignition.........wait 15 seconds....turn key on.....do not start....look at theft light.....should be blinking slow......normal mode.....when wait to start light goes out it should start normal
Step 3
Check fuse 30 amp.
Step 4
Is the odometer displaying correctly or is it dashes (------) while the truck is doing this? If the odometer has dashes and there are no codes being set, chances are the truck is losing communication with the pcm. This will also cause the theft light to flash and the truck to turn over but not start. If this is the case, check the wiring around the power distribution box under the hood. Also check all relays and fuses. Ford PCMs are pretty tough so that would be your last bet.
Things You'll Need
• Alarm keypad
• PATS programmed ignition key
Instructions
1. Press the unlock button on your vehicle's key fob to deactivate the alarm. If you've misplaced your remote for the car, use the PATS programmed key to unlock the driver's side door. Then, put the key in the ignition and turn the key to the "on" position. The vehicle's battery should be on, but the engine shouldn't be running.
2. Locate the override button on the alarm box, beneath the driver's side of the dashboard. Press the button and hold it in until the alarm beeps one time. The LED light for the alarm should stop blinking, indicating the anti-theft system is disabled.
3. To reset the vehicle's alarm, put the PATS programmed key in the ignition and turn the key to the "on" position. Press the override button. When the alarm resets, it chirps two times and the LED light begins blinking.
Step 5
Before you reset the battery; Press and hold the odometer SELECT/RESET button then turn the key to run. Keep holding the button till test shows in the odometer. Release the button. Press and release the button to scroll through the readings till you see dtc. If the cluster has any codes stored you will see them after the dtc.
Info on Ford PATS System
• The PATS system or passive anti-theft system on the F150 cannot be bypassed. The key has a built in chip that causes a ring on the key cylinder housing to send a radio signal to the PATS module to allow the truck to start. The PATS module then sends the ok to the PCM and instrument cluster. The little red theft light in the center of the dash should blink slowly when the truck is off, but if it is blinking fast when you are trying to start the truck, then it is not receiving a signal from the PATS module to allow it to crank. If you are hearing a single beep from the instrument cluster area while you are driving after first starting, I would be more inclined to think it is an instrument cluster problem. All three modules, the instrument cluster, PCM, and PATS must receive the signal to allow the vehicle to start. You could have a problem anywhere in the network. It would probably be wise to take the truck in for repair; something is causing the key input to not transfer to one of the modules. It could be one of many things, and the PATS system is very complicated and needs to be diagnosed by a professional.
If the factory alarm is armed you should be able to use the key in the door (lock it then unlock it) this should turn off the factory alarm if that's the problem. I would check to make sure it's not the starter relay or other similar problem also try smacking on the starter it may be stuck (seriously) but don't hammer on it just tape it while someone cranks the vehicle. You could check for sure by getting a test light $4 give or take and check all the fuses and relays and check for signal to the starter if there is signal at the starter then the starter is stuck or froze if there is no signal chances are there is a bad relay or blown fuse somewhere.

There is a PATS transceiver on steering column under the ignition lock cylinder area. but the main control for pats system is the instrument cluster. Normally when you have ------on the odometer, it means the pcm is down or has no ground or power, or not responding. try first to communicate with pcm. if pcm not responding, fix that problem first.
