i haven't (yet) had experience with a excavator but, on my rock crawler when i switch it on the escs will always do nothing, to get it to work you have to hold the controller at dead zero for a second or two before the esc will prime (its a saftey feature) so the pump not starting up could be as simple as setting the pump to off and playing with the trim. if it is a brushed motor on the pump then checking the output voltage on the esc can rule out the motor being dead or the pump seized if there is no voltage. or if there is voltage then you will have to check the motor/pump. can you turn it by hand/can you hear it trying to turn? if there is no voltage then you will know it is the esc causing the misery.
If the esc/pump is brushless (3 wires) then testing is much harder unless you have a spare motor you can plug in for testing.
I have the A9 its a nice radio, go to the monitor window and check that the pump trim is set to dead centre (i would assume) so that the esc can arm
