Answer 1

Has the car overheated? if the car has overheated you may have damaged the head gasket damage and coolant is gettings into the block that is why it might not start. 

if it has overheated take out the spark plugs and see if you see coolant inside, also I would check compression 

Standard: 172 psi

Minimum: 144 psi

Difference between each cylinder: 14psi

 

P0128 is for the thermostat most likely,

 

P0463 and P0183 are for the fuel pump

check the fuel pump fuse.

if the fuse is good and the car has no wiring issue (from an accident or something) the fuel pump needs to be replaced also if your fuel pressure is over or under 51 psi 

the car is suppose to have 51 psi of fuel pressure at idle
