Oil Pressure on 1991 Ford Ranger

What drives the oil pump? and what couldve possibly broke that wont spin the shaft to the oil pump anymore?

Asked by for the 1991 Ford Ranger
The oil pump is driven by the auxillary pulley/shaft inside the timing cover. This pulley is driven by the timing belt.

A broken timing belt would mean a non functional oil pump, among other things. What is your symptom?
