06 Impreza 2.5i issues

[Ormrotter]

So I've been having issues getting my 2006 subaru impreza 2.5i base model back on the road. It started with overheating after driving her for a while, but would not overheating at idle. It was leaking at the thermostat so I replaced that. It was reading codes for the intake valve solenoid and the emoil temp sensor, replaced those and then it wouldn't start. We changed out the fuel pump and fuel pump relay because it's cranking and it has spark but won't start. I just read the codes again and here are the codes it's giving me;
P1518
P0851
P1152
P1153
P0502
P0503
P0140

Can anyone give me any insight on this? I have shop experience about one year but this is beyond my expertise. I can change parts but diagnosis is above me. Thank you in advance.
