Hum, doesn’t sound good.
The car will not have permission to start if it’s in gear. If the pumps gone then it won’t be able to throw neutral and gain permission to start.
The only thing you can try is rock the car (handbrake off) and see if it’s in gear and corresponds with the gear indicator.
Failing that there is a fuse next to the F1 relay you can check. (there are two from memory, check both).
The usual procedure is the relay fries in the open position then runs the pump till it fries too.
You could check the battery cables:
The earth connector breaks where it goes to the cable on the Neg and on the positive, there are 3 piggyback wires that bolt on. I’ve seen those come loose and cause your symptoms.
The dash doesn’t flash when you attempt start does it? Sign of a low battery.
But it would appear your pump and relay have gone.
It’s not that expensive, the Alfa Selespeed pump is the same part and it’s under £200. Relay about £30 then you have to descide if your going to do it yourself or spend the £500 in labour.
You need to get the dead pump confirmed. SD ideally but you can pull the relay with the ignition on and bridge the relay terminal, high side and see if it spins into life.
