engine died
Check the fuel pump, fuel relay, fuel injection. One way to know if it's the fuel pump is to leave the key in the ignition to on and if you hear a buzz noise. If there noise is there then check the other two items.
See if you can change the voltage reg on the outside, if so you're in business for 20-30 bucks otherwise the whole alt replacement can cost $100-$300 depending if you are a DIY'r.
best of luck
