It will not crank
On this vehicle, this could be a few things, and without the means to test them, might be hard to find.
1) Dead or low battery, does the instrument cluster come on when you turn the ignition on? if so then battery isnt dead.
2) when turning the key to start, do you hear any noise at all? a click maybe from the starter solenoid?
if you hear a click each time you turn the key to start, it may be a bad starter or solenoid, if you dont hear a click, it could be a bad solenoid.
3) bad ignition switch, you can test this the easiest by removing the panel below the steering wheel to access the ignition harness, the starter wire on these older GM vehicles was either a yellow or a purple wire, quite thick, if you have a test light, probe the starter wire and turn the key to the start position, if your ignition switch is still good, the light will light up.
4) could also be the neutral safety switch, first try the force it a little harder into the park position and see if it starts, also try and start it in the neutral position as well (make sure you have the brake on!) if it starts in the neutral position, it could indicate a bad switch or slightly out of adjustment. this switch can be in 2 locations, either on the transmission, more common on front wheel drive, or attached to the lower end of the steering column under the dash, the connector on this switch could also be loose.
5) check under the hood near the battery positive connection and near the starter for burnt looking wires close to the connection, the section of wire will be a smaller diameter than the wire its connected too, this is called a fusible link, and is intended to act like a fuse, that isnt easily replaced without some wiring know how. if one of these has blown, its most likely a bad starter or solenoid as well.
6) last thing i could think of, if this car has a factory theft system (you can tell by looking at your key, below the head of your key will be a small black square with a small metal strip in the middle of it on each side if the key), check your instrument cluster when you turn the key on to see if the security light flashes, if the light flashes, that is the cause of your no crank, which means you will probable have to replace the ignition cylinder, as the connectors inside it have worn out and can no longer read the little black 'chip' on your key, which is actually a resistor, if the car doesnt see the correct resistor value on the key, it will not crank.
im sorry cant tell you exactly what the problem is without seeing it, but i hope i have given you some ideas.
