Anti theft system

You say 'won't turn over'. Do you means the engine is not cranking (turning over), or do you mean it cranks but doesn't 'start'? Did you disconnect the battery when you installed the fuel pump.

The flashing anti-theft light may be a clue here.

1. Insert the key into the driver's side door lock.
2. Turn the key once, but not all the way to unlock the door. Leave the key in this position for 40-60 seconds. ...
3. Do this again, but turn the key in the opposite direction.
4. Remove the key from the door, get into your Ford, and start the engine. The system should be reset.

Ford anti-theft systems don't act like that . If the PATS anti-theft system were the problem , it would not start at all . GM vehicles will act like that ,start then stall after a couple seconds . Now you will need to have new key's programmed into the vehicle . Depending on the type pats system it can disable the starter , That means the starter motor will not crank the engine . Or it disables the fuel system .

From my experience...
A non PATS coded key SHOULD not turn the STARTER...!

If ANTI-THEFT were invoked... you can attain a not start condition which the Owners Manual says must be cleared by the dealer.

A working PATS key should disable the anti theft... by turning the ignition on... ELSE try your other key.

The SecuriLock [PATS]
passive anti-theft system is not compatible with
non-Ford aftermarket remote start systems. Use of these systems may
result in vehicle starting problems and a loss of security protection.

Sounds like your anti theft engaged with the wrong key or the chip did not activate properly in you key. You can probably reset this by disconnecting the negative side of the battery for thirty seconds and trying again.

Have you checked for spark at the plugs and the fuel pressure ?
Can you hear the pump run for 3 seconds when you turn the key on ?

are you using a copy of the original key

you need to use the original key for the car

Antitheft and Alarm Systems: Description and Operation
ANTI-THEFT
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.
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, with over 72 million billion
combinations.
Each encoded ignition key must be programmed into the vehicle powertrain control
module (PCM) before it can be used to start the engine. There are special diagnostic
procedures that must be carried out if new encoded ignition keys are to be
configured.
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 electronic module. During each vehicle start sequence, the transceiver module
reads the encoded ignition key identification code and sends the data to the PCM.
The control functions are contained in the PCM. This module carries out all of the
PATS functions such as receiving the identification code from the encoded ignition
key and controlling engine enable. The PCM initiates the key interrogation sequence
when the vehicle ignition switch is turned to ON or START.
The PATS function uses the PCM to enable or disable the engine. All 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 located on top of the instrument panel. This
indicator will prove out for three seconds when the ignition switch is turned to ON
or START under normal operation. If there is a PATS problem, this indicator will
either flash rapidly or glow steadily (for more than three seconds) when the ignition
switch is turned to ON or START. PATS also "flashes" the theft indicator every two
seconds at ignition OFF to act as a visual theft deterrent.
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 issues. Remote start systems must be
removed before investigation of PATS-related no-start issues.

The PATs key is used on the following Ford family trucks and suvs:

FORD: 1996-2001 MUSTANG, TAURUS

Following are the instructions for programming a blank key (you must have at least one working key for this procedure).

The PAT

1. Make sure you have both keys.
2. Turn on car but don't start. Watch "theft" indicator untils it goes out.
3. Turn off and repeat procedure with second key.
4. After "theft light goes out, insert new key and turn on.
5. Wait until the theft indicator goes off and then turn off switch.
6. Wait thirty seconds. New key is now programmed into security module. Repeat for any other keys.


1. Erase any old codes by entering the factory code.(buttons will light up)
2. Press 1/2 button within 5 seconds.
3. Press 7/8 and 9/0 buttons at the same time within 5 seconds.

To set new code:

1. Enter factory code (numbers will light up)
2. Press 1/2 button within 5 seconds.
3. Enter personal 5 digit code(decide beforehand) within 5 seconds of each previous one.
To unlock all the doors,press the 3/4 button within 5 seconds of the driver door unlocking.
To lock all doors and set alarm system,press 7/8 and 9/0 at the same time.
To disarm or reset a triggered alarm,just enter personal or factory code.

Do not set a code with five of the same consecutive numbers. It's too easy for thieves to figure out.

Deactivating and Activating Autolock

To deactivate the "autolock":
With all doors and tailgate closed but NOT locked,and ignition OFF.
1. Enter 5 digit code
2. While holding 7/8 button in, press and release the 3/4 button.
3. Release 7/8 button
The horn will chirp once if the "autolock" was deactivated
or two times if "autolock" was activated.

To reactivate the system,repeat steps 1 thru 3

Alternate Method To Deactivate And Activate Autolock

Do steps [1] through [5] (below) within 30 seconds or you'll have to do it over. If you have to do it over, wait 30 seconds between attempts.
Close all doors securely.

1.Turn the ignition key to ON.

2.Press the power door UNLOCK control THREE times.

3.Turn the ignition key from ON to OFF.

4.Press the power door UNLOCK control THREE times.

5.Turn the ignition key back to ON .The doors should lock and unlock.

6.Press the power door UNLOCK control. The horn should chirp ONCE to confirm successful switching of the autolock system

Troubleshooting:

The engine does not start and LED remains off.
1. Check PATS system fuses
2. If alarm is fitted check if LED functions for alarm: if not check cigar lighter fuse (also used for LED)
3. If not go to main dealer

Engine does not start: LED flashes rapidly Leave ignition on until the LED starts to flash a 2 digit code: (sequence- pause-sequence)
Check the following codes:
Code flashes:
1:3 Key code not received. Is key screened by other keys or objects? Try different key: if okay then first key is faulty. If not go to main dealer
1:4 Partial code only received. Try again. If not okay use different key. If not go to main dealer
1:5 Key not programmed into PATS. Program key as above using master
1:6 Faulty link between PATS module and EECV Go to dealer .

ANTI-THEFT SYSTEM Passive anti-theft system
Your ignition key has a unique imbedded transponder which engages engine electronics and allows the vehicle to be started. Without the use of your special ignition key, the vehicle will not start.

During each vehicle start, the coded key is read by the anti-theft system. If the key’s ID code matches the code in the anti-theft system, the vehicle is enabled to start.

Anti-theft system
Briefly illuminates when the ignition is turned to the ON position to verify that the passive anti-theft system is operating properly.

Also, its possisble that tou have actovated the fuel pump switch.

CHeck it.

the light blinks when the system is armed. Normal.

Your key has to be able to communicate with the receiver in the ignition area. Does your other key work ok?

Anti-Theft 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.

• During each vehicle start sequence, the ignition key identification code is requested by the PATS module.
• If the key's ID code has been programmed into the system, the vehicle powertrain control module (PCM) (12A650) is allowed to operate; this allows the vehicle to start.
• If the key's ID code is not programmed into the PATS module, or if no encoded key is detected, then the vehicle PCM is disabled.

The PATS module, located under the driver side instrument panel, communicates the state of the security system to the PCM via the module communications network. The PCM, based on the communications from the PATS module, will determine if the vehicle's engine will be enabled to start. If the PCM prevents the vehicle from starting because of PATS, the PCM will store a DTC in memory.
-------------------------------------------------------------------------
The anti-theft vehicle protection system utilizes the THEFT indicator, located in the instrument cluster (10849), when the ignition switch is turned to the RUN/START position. The indicator provides system prove out and operating status to the customer or technician.
Each PATS ignition key holds electronics that give each key a unique ID code.
The PATS will activate the indicator signal when the ignition switch is turned to the RUN/START position. The THEFT indicator will turn ON for two seconds, then turn OFF.
If the THEFT indicator flashes for one minute or more, this indicates that there was no key code received.
When the vehicle ignition switch is placed in either RUN or START, the PATS module requests the ignition key ID code. The PATS module requests the ignition key ID code by supplying power, ground, and the carrier signal to the transceiver to energize the ignition key. After the energize period, the key transmits its ID code to the transceiver module, which sends it to the PATS module.
The PATS module then compares the received KEY ID code to those stored in memory (16 maximum). If the ID matches, the PATS module sends an enable signal to the PCM over the module communication network.
The passive vehicle protection system utilizes the engine management capabilities of the PCM to enable or disable the vehicle engine. The module communication network is used to send and receive messages to and from the PCM.
Within one second after engine start, the PCM must receive an enable signal from the PATS module through the module communication network or the engine is disabled before the vehicle can be moved.
If the PATS module recognizes a stored ignition key code but there is a module communication network concern preventing the PCM from recognizing the start enable signal from the PATS module, the vehicle engine will be disabled. If this happens, the PATS module will flash the THEFT indicator for one minute, then flash diagnostic trouble code 16 ten times to indicate there is a problem with the module communication network circuits or the PCM is not responding properly.
The passive vehicle protection system 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.
• Control module concern.
• Module communications network concern.
