When I start up it does no stay on

:banghead:

Need help. I have a 92 lumina, I try to turn on the car it kind of tries to turn on but it does not stay on. What can it be. Some body help me please. Thank you.

Can you be a little less vague? Does the car turn over but not start, does nothing happen when you turn the key? Does everything go dead when you turn the key to start? Please be a bit more specific and descriptive as to exactly what the car is doing.
