You need the system scanned for faults, the dealer is really just about the only one that has the expertise to fix the system.

It sounds like the anti-theft security system is engaged, this is keeping your vehicle from starting. I would recommend calling a local dealer where you are and ask them to help you. Hope this helps.

If the security or anti-theft light is flashing when you attempt to start your car, and the engine does not crank or does not start, you have an anti-theft problem. The system may not be recognizing your key's key-less entry signal, or there may be a fault in the anti-theft module or wiring.
There is a reset procedure to stop this anti-theft light flashing.many a times this helps The reset procedure is as follows:-- Reset the alarm by locking and unlocking the drivers side door.Do this a couple of times and then check it will reset the factory security system . If the reset procedure does not helps then its time to get the anti-theft system checked.There is a short circuit in the anti-theft system wiring.

Thanks. you can rate this solution and show your appreciation.

Make sure your battery is fully charged and good. Then leave the key on 'till the security light stops flashing (sometimes more than ten min). If it refuses to start or will not stop flashing, your ignition tumbler chip may have failed (requires tumbler replacement and re-set security again) Can't guarantee it will fix your problem, cause I can't see what else is going on from here...but that's where I'd go first!

I just had this same problem with a '96 . do you have a vats key in your '94? you need to bypass the VATS system. read some of the blogs on this site and it will tell you how to do it. I fixed mine with a $2 resistor from radio shack.

try unhooking battery for a few minutes and see if this resets radio
