Where is the fuel pump reset switch on a 1989 Toyota truck?

A 1989 Toyota truck does not have a fuel pump reset switch. Fuel pumps on vehicles of that era are typically controlled by the fuel pump relay, which is part of the vehicle's electrical system.

If you're having issues with your fuel pump, you'll need to investigate further. Here are some things to consider:

* Fuel Pump Relay: The fuel pump relay may be faulty. You can test the relay by swapping it with another relay in the fuse box.

* Fuel Pump Fuse: Check the fuel pump fuse in the fuse box to ensure it hasn't blown.

* Wiring: There could be a problem with the wiring leading to the fuel pump. Inspect the wiring for damage or corrosion.

* Fuel Pump: The fuel pump itself could be malfunctioning. This will require replacing the fuel pump.

Important Note: Working on a vehicle's fuel system can be dangerous. If you're not comfortable working with electrical systems, it's best to take your truck to a qualified mechanic for diagnosis and repair.
