You could have something draining the battery. A bad battery won't directly stop the coils from firing. Basically, a bad battery will make it so the starter can't spin the engine in order to start. Once it's fired up the alternator is producing power for everything. Check the voltage on your battery. If it's not at least 11 volts then it won't be enough to crank. You would need to have a parasitic draw test performed.
