    My 02 v6 is just firing on #2 and #6. I've replaced coil pack, wires, plugs, and crank position sensor. Ohm'd out wires from cps to pcm and wires from pcm to coils. Is there a way to check the signal from pcm to coil pack? If pcm is bad do I have to have it replaced at a ford dealer?

    PCM was bad. I got one from a wrecking yard and all plugs are firing now, but it still wont start. The theft light just flashes. My local ford dealer says they can't flash it since it came from a wrecking yard. Is there an easy way to bypass the coded keys?

    Ok from what I have been told you can't disable the pats key system. Try a local lock smith with the equipment to reflash keys.


    hope this helps.

    For Ford keys (1996 -early 1998 Ford, Lincoln, Mercury)
    If you want to initiate a new master key....
    1. Insert new key into ignition cylinder and turn it to the ON (RUN) position. The security light on the dash will flash for fifteen minutes.

    2. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder OFF and then back to the ON (RUN) position. The security light on the dash will flash for fifteen more minutes.

    3. When the security light stops flashing, you have FIVE minutes to start the next step. Turn the ignition cylinder to OFF and then back ON (RUN) position. The dash will flash for fifteen more minutes.

    4. After the security light stops flashing the third time, the new key has been programmed into the vehicles computer and will operate the car. It has replaced ALL the previous electronic key codes and is the ONLY key programmed into the vehicles computer.

    If you want to add a key....
    1. Insert an existing key into the ignition cylinder.

    2. Turn the ignition cylinder to ON (RUN) and back to OFF.

    3. Remove the existing key and, within 15 seconds, insert the new key and turn it to ON (RUN).

    4. The security light will light up for two seconds to indicate success in programming the key into the vehicle.

    5. Don't attempt to start the vehicle with any key for at least 1 minute.

    On-Board Programming Method "C"
    for Ford keys (Later 1998-newer Ford, Lincoln, Mercury)

    If you want to initiate a new master key....
    1. This requires that the vehicle be connected to special dealer equipment. There are two ten minute delays involved while this device erases all existing key programming and sets up the vehicle computer to accept new key codes. Two new keys should be ready because the system requires a minimum of two keys in the program. After the first two keys are programmed, additional keys can be entered individually by following the instructions for adding duplicate keys (below).

    If you want to add a key....
    **You must have two original keys to perform this procedure. If you only have one key, you WILL have to take it to the dealer to get it programmed**

    1. Insert and existing (working) key into the ignition cylinder.

    2. Turn the ignition cylinder ON (RUN) and back to OFF. Ignition should stay on for at least ONE SECOND.

    3. Remove the existing key and, within TEN seconds, insert a second working key and turn it to ON (RUN) and the back OFF. Ignition must be in ON for at least ONE second, but no more than TEN seconds. Remove the key.

    4. Insert the new key before TWENTY seconds have elapsed and turn it to ON (RUN). Leave it the ON position for at least ONE second and turn back to OFF.

    5. The security light will light up for THREE seconds to indicate that the new key has been successfully programmed.

    6. To program additional keys, repeat steps 1 through 5

    As a precautionary measure for all of the above procedures, you should wait at least one minute after you have performed this until you start your vehicle.​
