Buzz in the dash, alternator not working, all light on in dash

For a Pontiac sunfire 1998, Whenever I shift away from park, all light turn on in the dash, I hear a buzz in the dash (relay? without enough voltage) and alternator fails to recharge the battery. It is not the alternator (It has just been changed and the problem didn't go away).

Further test showed that the interior (dome) and exterior light flickered only while driving. The problem was that the battery rack is broken. The battery negative terminal connect to the motor (OK) but also to the frame of the car through the battery rack. Since that rack is broken, the grounding of the car was intermittent. Whenever I shifted, it made the motor move in relation to the frame of the car, so that's why is caused all the light to turn on in the dash.

How do you unlock a igniiton on a 1998 pontiact sunfire

its possible that you need to try and turn the steering wheel left and right (IT WILL TAKE SOME EFFORT) while trying to turn the key. and you dont need to put pressure on the key , turn it same as you would when starting it normally. you dont want to break the key off.also try and put the gear shift lever up into park at the same time( thats asuming its a automatic with shift lever on the steering colum) somtimes you can get the car to close to a curb or somthing and having pressure on the tires in a less than straight position will get you locked in on the sterring wheel,shift lever and key lock possition . so with one hand pull the steering wheel left with as much pressure as you can and at same time trying to turn key with your right hand.

2002 sunfire key stuck in the ignition (run) position, won't turn off, no gages working, and will not shift out of park. now the service and theft system lights are on

Sounds as if the ignition cylinder is bad. You will have to replace it if the key is stuck. It is a lot easier to replace with the key in the on position as that will be required to remove the cylinder. If you get the key out and then the cylinder will not turn, replacement of the cylinder will be more complicated

Sounds like the alternator , check the battery voltage . If you can start the car put a voltage tester across the battery terminals rev the engine if no rise in voltage your alternator is dead.
