Home boiler issues 😭

Came home last night after work and the house was cold, check the thermostat and it was calling for heat, checked the boiler and it was on lock out so pushed the button on the burner rest, it tried to fire but didn't, checked the oil supply to the boiler (I have run out before 😬) and ample oils getting to the boiler tried bleeding but still no go and didn't seem like there was alot of pressure when I was bleeding. So decided to take the side off the pump and have a look and turns out the pump drive had worn the key and wasn't turning the gear so wasn't pumping. I fashioned a drive key from an old Allen key and got it going again. Is it easy to get a new pump for the boiler or what do I need to change.
It's a grant vortex eco boiler out in the garage.

Good skill. RDB pumps are notoriously weak. I would advise getting one on standby .
I personally have never bothered changing the key as I can’t warranty the repair . It might be fine forever , it might fail tomorrow…
You will need a pressure gauge and manifold to set the new pump and a flue gas analyser to set the combustion.. usually I’ll put a new nozzle in if fitting a new pump .

Where do I find what nozzle I need to get

Should be in the boiler manual.. but if you cant measure the pump pressure and the flue gasses then probably just leave it alone.. You tread a fine line between it being inefficient/blowing itself out/burning the baffles or sooting itself into a horrible awful shitty mess.
