I have a 1996 Toyota Corolla DX with about 200k miles on it. It runs good for the most part, but recently had a problem where it would not start. Napa tested my alternator, which failed, so I installed a new one. Now the car starts but won't remain running. The battery is also new. What could be the cause?

Edit today I've noticed white smoke coming from exhaust as t you car starts to overheat... Not when the engine is cool though, only as the car overheats. The white smoke combined with the over heat along with decreases in my fuel effeciency and acceleration makes me wonder if it's the head gasket
