broke_sx

Hey, im new to the 240sx world and ive got a problem with my 89 ka24e.
I bought this car a few days ago and drove it home with almost no problem except some shaking, so i figured i would need a new motor mount and tune up. I got up the next morning and she started having problems starting where i would have to pump the gas to get her to start but once she started she would idle at about 800-1000rpm and drive ok with the occasional weird noise. Today i drove her home from my friends house and halfway home she stalled and started smoking and i started her back up and got her the few blocks home and popped the hood and she was smoking from around the injectors and making a sound like pressure escaping and the fuel rail has what looks like black marks around the firt two injectors and she wont start.
any ideas on what all might be wrong other than the injectors and fuel rail?
