What, exactly, is the problem?
check if your battery is low than usual ..might be alternator problem
I have the same problem with my 2004 Sunfire. Leave the ignition on for 10 minutes. Just let it sit for 10 minutes. No shorter than that time. And Should start.
When all warning lights come on and stay on in a 2002 Pontiac Sunfire, it typically indicates a problem with the vehicle's electrical system, often related to a malfunctioning battery, alternator, or a poor ground connection. A faulty ignition switch or a blown fuse could also trigger this issue. In some cases, it may be due to a failure in the vehicle's onboard diagnostics system. It's advisable to have the vehicle checked by a mechanic to diagnose and address the underlying problem.

Have vehicle scanned to determine the problem
The radio on your 2000 Sunfire is probably reading "loc". If this is the problem, you need to go to a Pontiac dealer and pay them to unlock the radio. This is an anti theft device to insure your radio can not function if it is removed. The cost is from 10 to 20$
I had a similar problem in a Pontiac Sunfire. The guy at the dealership said it's a common problem with the switches they use for fan control in Chevy/Pontiac vehicles. It's about a $10 part.
It is a common problem in most GM vehicles.
Your alternator is not working.
I had this problem on my disco 1. Turned out to be the alternator, which was replaced and the problem was fixed.
A bad PCV valve or a problem in the PCV system will cause this
