Which light? Is it the dome light? the headlights? the little annoying blinking one next to the radio? I might be able to help.
fuel shut off switch by front passenger door.
Turn off the defroster.
Check your alternator, Mine did the exact thing. The Battery light and the !!BRAKE!! Light came on and couldn'y figure it out for the hell of me, did volt tests while running and only had 12.5 volts on the battery. I changed the alternator ($179.99) and got back to the normal 14 or so volts while running and lights shut off. no idea why the brake light was on at all.
may just be a fuse. I had this happen to me in my 2000 leganza. It was in the fuse bux under the hood. On the inside of the cover look for the fuse labeled DIS. It's a 10 or 20 amp that controls the ignition pack. It has blown twice on me so if that's it buy extra fuses to keep in the car.
Does the engine turn over? If you are getting crank but not catching, it could be the emergency fuel shut off switch. It's located on the passenger side front. When you open the front passenger door look down in the well next to the seat. it's a little black rubber fob. Try pushing that and then try starting it. Hopefully it's that simple. If not need more description of problem. --- Learning more everyday about Daewoo' than I ever really wanted too!---
You need to have it checked for codes. You can then diagnose the cause.
it is right underneath the steering wheel gasket
Could be a coil or ICM, Ignition Control Module.
There are pages and pages and items that can cause a check engine light. You need to have it checked for codes with a scan tool. After repair light can be shut off with scan tool.
Does 2001 Chevy cavalier have a fuel shut off switch
This worked for me: open the car with the door key. Sit in and shut the door. Now operate the door lock using the lock tab on the drivers door four times very quickly ((lock then open four times). Press the close button on the fob. If the door locks again, you've done it. May well work for other cars too.
The fuel pump inertia ( shut off ) switch is in the right front passenger footwell , in the right hand corner by the kick panel . If the switch is " tripped " , the fuel reset light is supposed to light up in your gauge cluster
