White smoke in the exhaust is a sign of water in the engine. What is the level of the radiator? You may need a new head gasket or heads.

Have a 2000 pontiac grand am 2.4 liter having trouble starting when cold or hot black smoke strong fuel smell and miss when startd but clears up and runs ok after that ?
sounds like a bad fuel pressure regulator,this located on the fuel rail that the injectors are on it has a vacum hose going to it,a small one,if you remove this vacum hose and there is fuel on the hose side this is bad even just a small amount,there should be no liquid on the vacum hose side,becarefull when replacing,you must relieve all fuel pressure 1st

Backfiring, rough idel
I would check the exhaust pipe a little closewr. White smoke can also mean a blown head gasket. Check the tail pipe to see if moisture is present. Also check coolant level. A blown head gasket can also cause related problems.
