I can't remember but do 1st gen cars have the shift lock release like 2nd gen cars do? If so you could try that. If not that solenoid might actually be bad. If I recall something about the brake light switch can cause the car to remain in park. I had that issues on my CSC.
If the car was parked on an incline I would try rocking the car back and forth a bit then try to get it out of park.
