Help!! Went to start car....

Oh crap! Ok, I've had the stang in storage since November and had been starting it once in a while and it ran fine when I did it. Today I went to start it and it made really loud squealing noise(belt?) and it idled like crap. The squealing stop after 15 seconds then it died. I went to start it again this time it only idled like crap still, then I started to smell like something was burning and I started to see smoke caming from the engine compartment. Needless to say I shut it off and pop the hood and it was all smoky in there. I couldn't stick around to see what was wrong. So what the hell is up? Maybe the oil didn't have enough time to get to the pistons? Help me out please. I have to get it out by the 7th of this month! Thanks.

Thanks guys! It was a really bad burning smell. It didn't smell electrical, more rubberish than anything. And did I mention there was smoke? I did have time to really check for anything. All I noticed is that there is build of some sort of white stuff on the front accersories kinda like that power you get on the battery post. Would that have anything to do with it? Ok I'll be honest, last time I started the car was a month ago and have not driven it since I first store it. I don't think that it is a rodent cause the car is stored in one of those "store it yourself" storage places and there's a rolldown door that goes all the way to the ground so I doubt anything could've gotten in there. What else should I check for? Thanks again
