Where is the oil pressure SWITCH (not sender) on a 1985 Fiero V-6?
Where is the oil pressure SWITCH (not sender) on a 1985 Fiero V-6? My Fiero keeps blowing the 10A fuel pump fuse and my research has shown that the oil pressure switch on these cars acts as a backup for the the fuel pump relay. I have already replaced the fuel pump and filter. Additionally I have searched for any loose electrical ground / frayed wiring. Pretty sure it is the oil pressure switch which is a $5-10 part.

The pressure switch is mounted on or very near to the oil filter casting of the engine.
The power wire to the switch is orange/black. That is also the color of the power wire to the fuel pump relay. The power wire leaving the switch is tan/white and goes to the pump.
