Check to see if the floor on the passanger side is wet. If so, than your A/C drain clogged up and your ECM/computer got flodded by water causing all sorts of funky stuff happening. Right next to the gas pedal is a small cover attached to the computer. It has a clip in it. Remove the clip and tug on the cover. Look at the top of the computer to see if its rusted up. Remove the other side cover also, which is on passanger side floor next to your left foot(if you sitting in passenger seat). and check other side of ECM/computer. Check the ECM for rust on top.
If ALL of that looks OK, than I would replace the switch,(since you are telling me that the key got VERY hot) that is mounted on the back of the ignition cylinder. Its a white round switch that failes after a while especially car beeing 1996, just think about how many times that ignition has been turned ON/OFF since 1996. The mechanism in the switch failes, causing starting issues and funky electrical issues.
Does the car have a remote starter installed?? Or didi it have one in the past?? I have seen companies that install them cause some damage to the harnesses on the switch that is mounted to the back of the igniton cylinder. They use "scotch locks" to connect the remote starter and after a while the connection corrode and cause problems too.
Anyways, check the computer for rust first. Than I would install that switch on back of the igniton. You can buy the switch seperately. You dont need the whole ignition assembly/switch only. Switch is pretty cheap (approx $50 ?). Try that and post results. I would feel pretty good about the switch beeing faulty. I have ssen them fail in the past and that's where your power comes into for the starter circuit.(key getting HOT, switch shorting out, making the key hot and starting the car without the key)

it is a cable that links you transmision to the dashboard
i am not sure what the name of the cable is
but if you hold the start position and switch the gears to neutral it will start.

This
sounds funny but disconnecr the battery and then hook it back up-I did this and power was restored to my radio-I have no idea why this worked.

Good luck!!!!!!!!!

Replace your blower motor relay. It's located under the hood on the firewall passenger side.
