disco not starting again

thats right the damn disco didnt start this morning.
took it to work yesterday, drove it to etown and home no trouble
went out to start it to warm up and nothing.
tryed to jump just to make sure that its not the battery, nothing
so now i have to lay down in the snow covered ground when its 20 some
degrees out when i get home tomorrow from work in the dark. maybe i should set my self on fire to stay warm trying to find out what the hell is wrong with it now. so i gess i will start by testing the battery and check all the wires take them off clean everything AGAIN and hope that it will start. :mad:
