I just bought a red 93 stealth and when you shut the key off or if the car dies i lose my radio programming it is the stock wiring and i looked at the wiring no cut or splice jobs. the heater control unit also resets if i turn the key off. when i do turn the key back on it goes to 77 deg. no mater if it was set at 60deg. or even off before i turn the key to the off postion then back on. please help is it a possible body computer or bad groun or where can i find wiring diagrams thanks shawn

When you pull the key out, there are a number of systems that still get power (to preserve the memory). The lines that supplys them are called constant power. Something has interupted this. Probably near the battery.

Betcha the same thing is happening to your ECU where it is also getting reset everytime you remove the key. I remember a thread on 3si a while ago about a guy who was tackling this issue after he found his feul trims kept getting reset after shutting the motor off. Donno what came of that. Try a search on 3si.

I've been staring at the manual for about 20min. Letcha know if I find anything. Sorry I can't be more helpful.

Check fuse# 19 it is a 10A fuse.

where is fuse 19 i looked in the box under the hood and the one under left side of dash that one only goes to 15 or 16 fuses

Check fuses No. 1 (15A), No. 2 (10A), and No. 14 (30A) under the dash with an Ohm meter or test light.

Fuse Box Diagram from GTO manual page

To check with a test light connect the wire to ground, turn the ignition to ACC and probe the metal sticking out the tops of the fuses. If both sides light up the fuse can be considered good. This is an easy way to check them without pulling them. With a test light you could quickly check all the fuses.

Looking at the fuse doesn't always allow you to see if it is bad. High resistance or an small vibration break isn't visible to the naked eye.

---------------
When working a problem like this start at the device and work your way to the battery.

-If the device isn't getting power, the wire or connectors to the fuse box or fuse could be bad. If the fuse is good check the wires.

-If the fuse doesn't get power check the branch fuse under the hood. If that fuse is good check the wiring between the fuse boxes plus the ignition.

-If that fuse isn't getting power check the wiring between the underhood panel and the battery/alternator.

Check to see if your dome lights work or not. If they dont - its all on the same fuse. 10A fuse thats on the bottom most right one.
