According to the owner's manual - you need to shut off the ignition and wait about 10 minutes for the theft system to reset. It usually doesn't take a full ten minutes, in my experience, more like 5 minutes. My own online search about this indicates that this module can go out and leave you stranded - don't know about disconnecting it.

Engine rotates but will not start
When you turn the key all the way forward to start the vehicle, that not only turns your ignition system on, it also engages the starter and bendix drive. When you release the ignition switch, it returns to the position where the ignition is still hot, but the power to the side of the solenoid that engages the bendix drive is dead.
Take it down to AutoZone or other parts store. Have them pull the codes...they'll do it for free. This will give you a place to start. They can tell you what the codes mean.

you PROBABLY have a defective park/neutral safety switch
Cracked distributer cap or fuel pump
Turn the key forward for ten min. then shut the key off then try to start it.
There are a number of reasons why a 95 Cutlass would start then shut right off. The problem could be the fuel line going bad, the battery terminals could be dirty, or loose, or wires could be bad.
