The car was running fine one day then the next day it would not start. We tried jumping it thinking the battery might be dead and it still would niot start. The car has power until we take the jumper cables off, then it seems like the battery is completely dead. When we jump the car it semms like it wants to turn over but just doesn't have enough power or something is keeping it from starting.

Sounds like you have a toasted battery or alternator. Have you performed a load test on the battery? Have you tried to charge the battery? First remove the battery and charge it externally from the vehicle. If the battery won't hold a charge, or won't hold a charge of 12 volts, replace it. Once you have the vehicle started, test the operation of the alternator. It should be putting out at least 13 volts back to the battery to keep it charged - if it is putting less than 13 volts or more than 16 volts, replace the alternator.
