Wanted to drive this while my mk3 vr6 golf is off the road and then pass the polo onto my daughter as her first car.

Picked it up for £125 knowing it was'nt running and brought it home on a trailer.
Bodywork and interior are in good condition so think I will try and get her on the road.
Owner mentioned about oil pump, she is not seized and turns over starting briefly sometimes but cutting out when revs go down below 3000.
Does this sound like the oil pump or not????? Or would i be better changing the engine???
Any help and advice would be greatly appreciated.
