You have ascertained that the burner fires and the pump does not run at
times causing the overheat problem. You could have a multi-meter, mains
tester screwdriver or a temporary light attached to the wires of the pump.
If the pump does not run and say the bulb lights up, then it is most
probably the pump. If no signal to run the pump, then something deeper and
the pump is fine. The burner should never fire without the pump running.
