Answer 1

P0443 EVAP purge solenoid circuit

When the CK ENG LT comes on right after the ignition is turned on you have a hard code set, what the ECM  does is to look for open circuit short circuit and grounds,  The EVAP purge solenoid is fused protected, if the there was no power to the purge solenoid the EVAP code would set  when the EVAP monitor conditions are met, because it comes on right way the ECM detected a open circuit or short, majority of times this is a fault with the ECM.
