With over-heating, you may have internal engine damage, hope not? W/o compression, it won't start. Make sure battery has a full charge and connections all good. If it cranks good but won't start, have a helper crank it while visually check for spark at the plugs. Use a gage and check proper fuel pressure and fuel injector pulse. Any applicable trouble codes? Those checks are the basics, in my opinion. If no compression, your cranking rpms may sound faster than normal.
