I've got a 2003 Oldsmobile Alero that will not start. The only thing that happens is when the key is in the ACC position the light "service engine soon" comes on. When I try to start it the light goes off and nothing happens at all. Now I've realized the lights don't work, power windows, radio or anything. This morning my keyless entry worked before getting in my car and trying to start it but now it doesn't. It seems like I've blown a fuse but I can't find any that look blown. I don't have a light meter to be 100% sure however. I had my neighbor come over and try to jump my car but nothing at all happened then either. HELP PLEASE

i would assume a sensor before a fuse

Sounds like a common problem ignition switch, These cars.
