Disconnect the battery and join the leads together ,leave for half hour then reconnect the battery and try again,failing which try the spare key and look at the main key as often with ford keys the chip falls out ,its a little round glass thing on a lot of models but somethimes it can be a little piece of black plastic sort of thing.

The dealer may have to re-program the Anti-Theft processor to get the car started.
Hope this helps.

Either you may be using a key that you had copied from the original or your chip went bad in your original key. Most of cars now a days have the key censor in the key so if it is the incorrect key it will not start your car or if it does not read that chip it will not start

SOURCE: 1998 ford expedition wont start. theft like is

If you are reseting a factory alarm...lock and unlock the drivers door with the key. If you don't know the code look under the dash driver side in left corner there should be a black cover with a sticker with a code on it 6 numbers that is the factory code.

SOURCE: 1998 ford expedition that won't start. it cranks,

The theft light blinking indicates a PATS (perimeter anti-theft concern.It means that the computer has not recieved a signal from your key when trying to start the vehicle. A few things could be wrong.
1...The key you are using to start the vehicle is not programmed to the vehicle or broken internally. So try a different key(one that you know is programmed to the vehicle) if you have more than 1. If the theft light goes on and flashes when you try to start the vehicle, you must wait about 5 minutes before trying the second key because the computer goes into antiscan or theft mode and wont let any keys start the vehicle.
2... There is a small transciever ring located arount the key cylinder which recieves the key signal. The wiring for the tranciever runs down the steering column into the dashboard wiring. Sometimes these wires break. If you have a tilt steering wheel, move it all the way down and try to start, then try moving it all the way up and try to start. Keep in mind the antiscan that I mentioned in #1. If this works then you need to check the wiring at the base of the steering column. A white connector with 4 wires. Pull on each wire to see if any are broken.
3... Check fuse #30 on interior fuse panel. If it is blown then you will have to trace down the cause of the short. The ignition coils are on this fuse also so one could be shorted. Disconnect all ignition coils(you may have 8 located on each plug if 5.4l engine or 2 located on l+r front of engine if 4.6l engine) and see if the short is gone. If the short is still present disconnect the radio noise supression capacitors( small black box approx 1" x 1" square with a single wire coming out) that are located on the left and right front of the engine. Pay close attention to all the wiring around the coils, look for any areas that may have rubbed thru and shorted.
These are things that I would look for first and are the most likely causes. This should get you started in the right direction. Be patient and post your findings if you fix it or not.
Good luck

Vehicle will not start! Replaced the battery but it will still not turn over. Oil light, battery and engine light come on when initially trying to start.


Is the security light on or flashing when trying to start the vehicle .
Anti-Theft The passive anti-theft system (PATS) consists of the following components:
  • Anti-theft indicator
  • Encoded ignition key(s) (the key contains a transponder)
  • PATS transceiver
  • Powertrain control module (PCM)
PATS will disable the vehicle from starting if there is:
  • a damaged PATS key.
  • an unprogrammed PATS key.
  • a non-encoded key (a conventional key or one that does not have any electronics).
  • damaged wiring.
  • a damaged transceiver.
  • a damaged PCM.
If it is a anti-theft system you will have to take it to the dealer .This system will keep the starter from spinning the engine .

A focus was running good, but unexpectedly power cut, and i can not to starting again. where localizate a inmobilizer system in the car. Thanks in advance.


Hi ROBERTO... what year focus ? is there a little red light blinking very fast in the center of the dash pad when you try to start the car ? If so that is a problem with ( PATS ) passive anti-theft system. that is what ford calls it ,not immobilizer .If not it's not the anti-theft. Does the engine crank over ? if so there again it's not the anti-theft system . If it cranks over I'd look for a no spark or no fuel condition , and go from there. hope this helps ! let me know if you need more advice !

How do I stop the anti-theft device red blinking light? Car is off and locked and from the window can see the red light blinking.


the red light drain 0.001amp. from you battery.need 1000 hour to drain 1 amp. test the battery if is any good. do drain test on the car.rust and short will drain battery overnight.after market equipment,light in the trunk or glove box, under hood light etc. disconnect the battery and install amp meter. do the drain test. your computers uses 0.2-0.4amp when sleep.anything over 0.5-.6 amp is bad. after you connect the amp meter give 1min. to turn all systems to sleep mode.Is normal the first minute to be high drain.
ones you know something is wrong disconnect the fuses one at the time and note if any changes. if the fuse you disconnect turn the amps low note what system is connected to the fuse and you will know were is the problem

2003 f150 turns over but wont crank, also theft light blinking fast


Usually means the sensor in the lock cylinder is not reading the code in the key.
If the pass key system does not get the right signal from the key the truck will not start.
You might try taking the key off your ring - put it in the lock and turn the switch on - but don't crank it for at least a minute.
There are procedures to reset the anti-theft online - - if you do a search for resetting anti-theft F150 you can read them.

My 98 ford explorer wont crank theft light is blinking real fast and radio and everything works


Whats happening is your PATS (Passive Anti Theft System or security system) is not programmed and can't read the code that is being transmitted from inside your key. There is only 2 solutions to this and one is going to cost you money... sorry. We'll start with the free solution.


1. First thing is that you will need 2 keys that are or were programmed to your vehicle. You are going to have to cycle your keys and you cant fool the system by using only one. Insert the first key and turn it to the run position for approximately 6 seconds then remove it and within 5 seconds insert the second key and do the same thing. Pull that key out. Now your vehicle should start with both keys and the theft light should be back to normal.

If this doesn't work option 2 is you have to take it to a Ford dealership and they will have to fix it for you. Hopefully this isn't the road you have to take. I work at Ford and am one of the few in our dealership who program keys. All the best and I hope solution 1 works for ya.

98 ford explorer wont start theft light on while cranking, no fuel presure at fuel rail


It sounds like the vehicle is in theft mode,did you use a different key? Does the theft light blink really fast with the key off?If the passive anti-theft system has been activated the computer will have to be reset in order to get the vehicle running again.
