Assuming it is the same as my 92, it is inside the tank. DISCONNECT THE BATTERY SO THAT YOU DON'T THROW SPARKS!!!! And don't smoke when you're playing with the fuel. Drop the tank by first removing the clamp around the fill spout and then releasing the two support straps. Have the tank supported while you lower it just a little. I hope your tank isn't full like mine was when MY fuel pump went out last summer. Disconnect the wiring and fuel lines, then remove the tank from under the vehicle. Clean debris from around the top of the tank and dig through the sealing tar that is used to protect the tank from water and dirt, then remove the screws and carefully lift the assembly. You will want to save the fuel level sensor, but the entire fuel pump and filter assembly is included in a replacement pump kit. Good luck and be very careful around the fuel. ANOTHER ANSWER: I think the previous responder thought your question was where to find the 'fuel pump', not the 'relay'. There is a removable cover in the engine compartment on the firewall in front of the passenger. You'll find your relay under that cover.

The starter relay can be found underneath the hood on a 1991 Nissan pickup. The starter relay is beside the battery on the passenger side.

The 1991 Chevrolet S 10 pickup truck oil sending unit is located on the bottom of the engine, in the oil pan. You will need to remove the oil pan in order to access the oil sending unit.
