Engine Mechanical problem
1993 Nissan Primera Automatic

Hi there.

Ummm my car all of a sudden just wouldn't turn on.
Before that i noticed that it was over heating so i bought some coolant and put that in the car. That was all good. Then i took off, started driving, then the next time i turned the car off that was it.Just stopped turning over.
All the electricals go.Lights turn on and everything, radio and such. Its when i turn the key theas no jolt or kick, no noise to say that it might turn over.
But when i do turn the key a light does come on.
A little sign that looks like a pipe square with three steam lines.

Heas hoping you can help me please.
Just wanting to know if its my cars majorly damaged.
Thank YOu.
Tara.
