[2g2fast]

Hello, everyone i bought a 97 GST eclipse like 4 months ago haven't got around to fix it and now i either need to fix it myself or take it to a shop in the Chicago Area.
I have 3 error codes and i dont know how to fix them.
P0443
P1105
P1400
Can anyone help me with these codes and if you had this code what did you do to fix them? Pics/links

p1400 Manifold Differential Pressure Sensor circuit. p1105 Fuel Pressure Solenoid. p443 EVAP System Purge Control Valve circuit.

someone might of deleted the evap system or egr so thats why your getting p443.
