Where is the oil pressure sending unit located on a 1986 Pontiac fiero 2.8 liter engine?

The oil pressure sending unit on a 1986 Pontiac Fiero 2.8L V6 is located on the passenger side (right side) of the engine block, near the front. It's a relatively small unit and often has a single wire connector attached. You'll likely need to look closely and perhaps use a flashlight to spot it. It's typically near the oil filter but not directly on top of it.
