Start Circuit disable sounds like a fault in your passlock system. Its not uncommon for these to fail overtime. If your car starts fine then it may only be a matter of time before it fails.

The EVAP code might be a loose vac line to your EVAP solinoid, gas cap not tight enough or a bad soleoid. Check all the connections and vac lines to the EVAP to be sure.

Also clear the codes and restart the car, see if they come back.
