I have an 04 Pontiac sunfire,yesterday drove car shut it off 15 min. later wouldn't start. Lastnight started fine. drove to work today car ran fine, got off work car wouldn't start

SOURCE: 1999 pontiac sunfire will not start

Maybe the starter is not notify to the engine.

SOURCE: engine intermitantly stalls

if this a fuel injected car just check to fuel pressure first.

SOURCE: Car no longer starts

sounds like a bad battery or bad alternator.its going to be one of the two...have both checked

SOURCE: 04 pontiac sunfire battery light and panel lights dim

sounds like your alternator. if you have a multimeter then turn on your car and turn your headlights on/ac and heater fan on high/wipers on and blinkers on. once they are all on hook the meter to the battery and if it reads less then 14 volts then the alt is bad. or you can just take it to a shop and have it tested.

Your car is equipped with a system called PASSKEY standard on all GM cars and light trucks, try the following procedure to reset the system, the battery being dead will trigger the system.

PASSKEY LOCKOUT RESET GM CARS 1999 UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key.
