My '98 Ford Taurus won't start

"Security" or Key-shaped light flashes on the dashboard ? Your car might be equipped with an immobilizer. (you can find more information about the immobilizer in your owner's manual). The immobilizer allows the engine to run only if the correct key is used. If your car has an immobilizer, you probably see a "Security" or Key-shaped light coming on on the dashboard every time you turn the ignition ON. If this light is flashing when you turn the ignition ON, it could mean that there is some problem with an immobilizer or the system does not recognize the key. If the immobilizer doesn't recognize the key, the engine wold not start at all, or would start and then die in few seconds.
You can try a spare key, if it won't work, your dealer is the place to call. Sometimes, the key is just need to be reprogrammed.

SOURCE: electronic immobilizer

most likely cause is the gauge cluster, this will have to be tested and service by your local dealership because the dash cluster and keys have to be coded. I have seen the immobilizer loose it's coding for apearantly no reason. therefore have them recode cluster and see if problem goes away, if it doesn't the gauge cluster will have to be replaced.

SOURCE: immobilizer

If there is a blinking car icon with an "X" over it. This icon means the Immobilizer has been activated and hence won't allow the car to start. It could be due to a bad SCU, Start Control Unit. The SCU is actually the ignition switch on these cars.
Most of the time it's triggered by the anti-theft system..You can try this trick i learned that the dealers won't tell you...try locking and unlocking of the doors five times with the remote to reset the immobilizer and see if this helps.
Good luck..i hope this helps...please take a minute to rate me a fixya.
