Where is the fuel pump relay on a Datsun?
Where is the fuel pump relay on a Datsun?
Look Under Here! To find it, look under the dash on the passenger’s side. It is just visible above the kick panel in front of the door and will have the auto choke relay attached, and in automatic trucks, the fuel cut solenoid. The fuel pump relay itself has a 6-pin connector going into it.
What kind of fuel pump does a 1981 Datsun have?
I have a 1981 Datsun and a 1984 Nissan and they both have this troublesome black box. Your repair guide not only ignores it, but it is conspicuously absent from the wiring diagrams, making diagnosing and repairing electric fuel pump problems virtually impossible.
What is the ignition switch position on a Datsun?
The ignition switch start position (power to white wire at start using fuse #5). The alternator (power to white/blue wire when running). The oil pressure switch or oil sending unit (4WD) (yellow/green). This is a wiring diagram for the fuel pump relay terminal that I created using the Haynes color codes found in my harness.
Where is the fuel pump wire located on a Nissan?
Why Nissan used a white/black wire from the relay to the body harness connector (found under the carpet beneath the passenger’s seat) is a mystery to me. All other fuel-related wires throughout the truck are brown as is the connecting terminal in the body harness connector which goes directly to the fuel pump.

How many pins are in the fuel pump relay?
The fuel pump relay itself has a 6-pin connector going into it. Those are six wires that you will not find on your wiring diagrams. Do not try to remove the harness from the relay unless you have forearm muscles like Popeye. Remove the attached relay (s) and then undo the two screws holding the fuel pump relay to the panel.
How long does a Nissan fuel pump relay last?
A factory relay is labeled Jideco, and if you choose to replace it, they seem to last about 20 years. On the back of the assembly are four Phillips screws. Once removed, the cover and insulator come off and you’re looking at the circuit board of the relay itself.
