Hey guys my mums car has been siting for 2 years and we are trying to get it going but when the key is turned to accessories there is a buzz noise the catalytic converter overheat comes on and the starter motor won’t work or even make a noise. We have checked all the fuses the battery is new and the engine isn’t seazed

Check the starter relay. The eccs/ecu relay sounds to be right as the buzzing will be the fuel pump that the ecu switches.

If the relay is good, get under the car and give the starter a tap with a hammer as it may jammed. 

Following that get a multimeter and see if there is voltage to the start solenoid.
