I dont know shit about cars..I dont even know if this is a place where I can get help..

I own a 1993 Mazda Protege.
It wont start.
It wont turn over. My friends said it was the silinoid...WOW thats great
But I dont know shit about cars...so.. I dont know where this things at..how to fix it or anything.
IF anyone could tell me..that would be great. Apparently since its so old its supposed to have carbon scorches on it?? idk.. anyway It needs to be replaced or cleaned.. so any assistance would be great..
my email is jedi_revan@hotmail.com send any helpful hints there..or sites that would be able to help me faster. Thanks
