Not enough information regarding why the car won't start but as to he security light; it's always blinking when the engine is off.
change the blue box maybe.
it might be the chip in the key. i know it does it in later model cars.
Sometimes my sons 2001 Grand Am does that. It has to do with the Security System. Turn the key to ACC the Security light will start blinking and will continue to do so for 10 minutes. At that time the Security Light will stay on. At that point you can start you car. This works for him Good Luck.

From what ive read it is the passive security system, it reads a chip in the key once inserted and stops blinking. in other words the car wont start without the chipped ford key
usally all that needs to be done is the pcm needs reprogramed but a technition will need to do it.
try putting petrol in
always on nomatter what i do
have a qualified mechanic work on it.
The security system shuts the whole car down so that it cant be stolen.

depending on the year you can disconnect the positive battery cable for a few minutes and then reconnect it. it may reset the security system.
