Pull the dash/cluster. most likely corrosion at the plug/s in the back of it. Or a ground problem.

I had the same problem. Goodwrench looked at my car for 2 hours could not figure it out. Then they unpluged the body control module and plugged it back in and presto, problem solved.

SOURCE: 2001 Pontiac Sunfire Fuel Problem

Are you certain that the engine is getting fuel? If not, then you will have to verify that there isn't any blockage in the fuel system to prevent the fuel from reaching the engine. If fuel is reaching the engine, try the following
1. Check compression values for each cylinder.

2. Inspect electrical circuitry in the distributor assembly (slack wires, broken wires, dmaged rotor etc)

3. Check to see if the timing belt was not severed. This belt transmits the drive from the crankshaft to the camshaft. If the belt ius severed, the camshaft cannot rotate in order to open the valves

SOURCE: Battery and Alternator Good. Alternator not working. HELP!!!

djn, I believe you have some accessory that is on when the key is in the off position.
Check to make certain glove box light is not on when the glove box door is closed and the trunk light is not on.
If you have an aftermarket radio or any added accessories make sure they are not wired direct to battery voltage.
If all that checks out, disconnect the battery negative and connect a test light between the battery and battery cable. If the light is on you have a drain in the electrical system. Leave the light connected and begin removing 1 fuse at a time until the light goes out, that will tell you what component or circuit is draining the battery.
Last resort, you may have an alternator drawing the battery down.
Good luck and let me know.
Regards,

SOURCE: I replaced the head gasket on my 97 Sunfire it doesn't start

If your timing is off you will have no power.check and make sure all timing mark's are correct.Some engine's are contact motor's,which mean's if your timing is off you could cause damage to valve's or piston's.Also you should do a compression test to be sure each cylinder has adequite pressure.Hope this help's.

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.

Hi, airbag deployment rarely causing damage to the wiring in the dash. The gauge cluster may of been damaged internally, but this usually shows up right away after repairs are done. I would check the connector on the PCM it is a cam lock design and if its been damaged or not closed properly it can cause crazy things to happen to the gauges. Good luck.
