I'm not sure what the "auto start battery" is.
If your vehicle will not start, the first step is to check the state of charge and the ability to sustain a load by the 12 volt battery.
If the battery checks good, you'll have to check into the starting system - starter motor, cabling and related.
Too hard to say what's going on until testing is performed.
