ignition won't work ignition switch is ok. what could it be?

Hello, Start by checking the starting and charging system. This would start with the battery. Ensure the battery is fully charged and able to handle a load. Ensure that the vehicle is securely shifted to park or neutral. Try one or the other and move the shift lever around, in case the neutral switch is a concern. Check all wiring and cabling to the battery and starter. Check to see if the starter is binding or drawing too much amperage. This is all a start; hands on diagnostic testing is needed to find out what's wrong.
