Why Me?!?!

Yay! Another problem with my car!! I love having an svx (not really... b/c it all ever does is BREAKS!) anyway. enough of my complaining. so, the new and current issue of my car is this. the other day it would not start. it has a 3/4 tank of premium gas, charged battery, and a new oil changed (about 2 days old) so i try to start my car and it doesn't start, when i finally do get it to start the engine shakes really hard and greyish blueish exhaust comes out of the exhaust pipes. does anyone know what this could be? I was not going to drive my car like that, so i hung out at my friends house for awhile to let it settle thinking if i gave it a few hours it would be ok to drive home (30 min drive) and then i tried to start it later on in the afternoon and it would not turn over at all. So I'm kinda worried and my car is still currently at a friends house because it won't start... can anyone help me???
