I might be able to shed a little light here. The radio has a code that needs to be re-entered after you disconnect the battery. If you don't know the code, you have a couple of options. One is to take the car to a dealership and ask for help. I'm told that they can do it easily, but charge an arm and a leg to do it. The other option is Ebay. Yep! Ebay. There are guys there who will sell you the directions on how to retrieve the code, or at least how to get started. There are also guys there who will sell you the directions how to reprogram your key fob. I've actually used the key fob directions they provided for my '96 with success.
KEY FOB: basicly, pull the carpet away from the inside of the rear driver's side fender inside the trunk. If you see a black box there, continue. If you don't, these directions won't work for you. Coming out of the black box is a connector which has nothing plugged into it. Fashion a paper clip or piece of wire into a U shape. Stick it in the connector to effectively short it. You should hear the power locks cycle. While holding the clip in place, press and hold any button on the key fob until you hear the locks cycle again. You're done. Now, I've had varying luck getting the locks to cycle the second time, but the key fob worked. It's worth a try!

No way, only if the battery fails under a load test
In order to wire the starter on a Pontiac Sunfire, you will need a jack, jack stand, socket set, and a torque wrench. You will need to make sure to remove the battery cables from the battery.
You have a bad alternator.
You have to unplug the ground from your battery for 1 or 2 minutes.
On a 98 Pontiac Sunfire, the red color of wire goes on the terminal marked "B" on the starter. This terminal is located close to the battery of the vehicle.
It could be your alternator is going bad
the starter relay is located on the rad support near the battery
Well there is 2 ways to check....it could be your alternater or your battery....to check to see if it is your alternater pull of your positive cable and if the car dies it is your alternater if your car don't die then it is the battery and you might want to get that replaced
split the fob halfs and the battery will be on the backside of the board!
disconnect the negative battery cable for 10 mins this will reset computer it will do it for sure
To change the spark coil pack on a 1998 Pontiac Sunfire with a 2.4 engine, first disconnect the battery. Then remove the coil pack and spark plug. The spark plug should also be replaced with the new coil pack for best performance. Insert the new spark plug, then the new coil pack being careful not to bump any of the many other electronic parts. Then reconnect the battery.
check if your battery is low than usual ..might be alternator problem
