    Well you didn't mention mileage. I assume, either you have fery little to no oil in the engine, and thus wore out the oil pump. Or due to the high mileage, it has wore out from that. I'd most likely assume that its neglect, like you stated. And also, could be the oil pan is kind of crushed into the oil pump pick up screen. Is possible, and have seen on some customer cars, where someone has done that to change a tire. Good luck.
