When an engine is on full bore and pulling hard it is using more fuel and consequently produces a lot more heat - at least 60% of the fuel used is turned into heat; fortunately most of it is ejected through the exhaust though a significant amount is radiated from the metalwork of the engine and ancillaries and sent into the fuel tank through the return line (keep the tank more than a quarter full) and that still leaves a considerable amount of heat to be dissipated by the radiator.
The situation is made worse as uphill travel is at a lower road speed and therefore there is less ram air effect on the radiator and the cooling fan is left to do all the work.

The principle cause of a failure to dissipate the heat is either insufficient airflow through the radiator, insufficient coolant circulation or a combination of both.

Assuming coolant loss isn't the cause of overheating...
While it isn't unknown for a water pump to lose a vane and it is far from unknown that a defective thermostat can be a cause of overheating, the common cause of reduced coolant circulation is a partially blocked radiator core.

Reduced airflow is commonly caused by mud and insects clogging the radiator gills, mechanical damage to the gills, slipping drivebelts, defective viscous or thermal fan drives, inoperative electric fan, forgotten winter radiator masks...
It is also not unusual for a fan cowling to be omitted during service in order to make subsequent work easier - fan cowlings are important...

If the fuel pump and fuel gauge sensor shares the same housing as is often the case - maybe the person that fitted the pump damaged the sensor or float...
Alternatively it could be a wiring or connector problem, defective gauge or printed circuit.

If there is a black wire, connect it to the negative side of battery and try positive to either of the other wires to see if it activates the motor.

Reach under from the front and operate the cable by hand.

For an engine to start and run you need 3 things:

1) fuel.
2) ignition.
3) air.

if 1 or more of these are missing you will not have a running engine, check these 3 things are present.

The code means that the temperature in the catalyst is not high enough to support hydrocarbon conversion. Some ways to troubleshoot are:
1. Replace the EGR cooler
2. Check for exhaust leaks
3. Install clean DOC and DPC
4. Check that there are no issues with the 7th injector, fuel metering block for injector, WGR cooler, the engine's wiring and DPF sensor
5. Check if the 7th injector is receiving good voltage when the car is on
6. Replace the wire harness if the issue is persistent
If the issue isn't fixed now, drive down to the nearest mechanic.

I would start with having the OBD read and any fault codes should be cleared and take it from there
