Need to know where the fuse is for oil sending unit on a 1998 Buick Park Avenue with a 3800 v6

There is no fuse for the oil sending unit ! Oil lite on , gauge not working ? Do you know what PCM five volt reference voltage is ? The PCM - engine computer supply's a stable 5 volt voltage to engine sensors . The oil pressure sensor is one of these sensors .
Engine Oil Pressure Sensor
The engine oil pressure sensor is a solid state transducer. The engine oil pressure sensor sends oil pressure information to the PCM. The PCM then transmits the oil pressure information to the IPC via serial data.
Engine oil pressure is displayed on the scan tool in volts. A low voltage reading indicates low oil pressure. As the oil pressure increases, the voltage level also increases. The normal range of the engine oil level sensor signal voltage is 0.5 volts at 0 kPa (0 psi) to 4.5 volts at 883 kPa (128 psi).

Engine 3800 for 98 Park ave. shows oil pressure too high on the gauge. what could cause this

Sounds like your oil pressure sending unit is faulty! When you turn the key on, is the gauge reading low, then you start it and it pegs out? if so, the sending unit has failed.

My oil light is flashing & chiming when I drive. But my oil isn't low

Sounds like the low oil sensor is bad or corroded. Check and clean. If that doesn't fix, replace it.
