Sounds to me like a clogged fuel filter or your fuel pump is going out.....I would check and replace the filter first......

SOURCE: 2000 pontiac sunfire starts only when gas pedal is

If you have excessive white smoke coming from the vehicles exhaust, it sounds like your headgasket is failing. Especially having a rough idle too. Check your coolant level, does your exhaust smoke smell sweet, like Antifreeze? If so, the gasket has blown. Hope this helps...

You need to rebuild the carburetor is my opinion based on your symptoms. The carb rebuild kit comes with full instructions and you can get it here.
