I had the same problem with 2 cavaliers of mine ( which are basically the same as a sunfire) and my suggestion is the head gasket is bad or u have a cracked head most likely in between the valves.
When you say that the gas pedal is to the floor, I'm guessing that you mean this is what you have to do to keep her running. It kind of sounds like you might have a blown head gasket. Check for water in your oil. FriPilot
The neutral safety switch is found under the clutch pedal on a Pontiac Sunfire. Crawl under the cars steering column to see and reach the unit.
Well, we need lots more information here. Is the clutch pedal actually "stuck" to the floor? In other words, can you NOT lift the pedal up to the normal position? OR, has the clutch pedal "fallen" to the floor due to no resistance from the clutch?
why is my brake pedal hard on 2003 sunfirer
under dash drivers side mounted above the brake pedal
Under the floor below the brake pedal.
It could be that something in the pedal is bent/broken. More than likely the cable is binding. I'd replace the cable if nothing else is visibly causing the problem.
Um, somebody took it? Seriously, I'm guessing that you mean it goes to the floor with no resistance? We need a little more info here, please. FriPilot Is this car equipped with an automatic transmission? 1. Check to see if the clutch cable is broken or disconnected
Try putting the pedal to the floor while cranking it
The brake light switch is located on the brake pedal bracket. You'll need to remove the trim panel beneath the steering column to get to the switch and the connector.
