87 wont kill the car it will just make it run like crap. Is it even an SR car? You need to trouble shoot with the FSM. Check your fuses, check your signal to the starter. Check your ignition...

It can be plenty of things but nobody can really help you until you get at there and go through the basics.

current(ignition), fuel, spark...
