Best Answer

Testing the fuel pump is easy, and makes sense prior to dropping the tank to replace the pump. In the Engine Compartment on the passenger's side, there is a small box located on the fender well and should read "Diag" or "Diagnos". Open this box, on the inside/top of the box, there is a diagram for the electrical layout. One should be labelled "FP", and is most likely top left. Take a test wire and plug it into the "FP" receptacle and jump directly to positive side of battery terminal. If your pump is good, you will hear it running. If your pump is good, you most likely have a problem with your fuel pump relay located in the passenger's kick panel.

How do you replace engine air filter on Toyota 4Runner?

The Toyota 4Runner light truck has been in continuous production for multiple years as of September 2014. For these reasons the exact intake and air filter plenum design varies by model year. For the 2014 4Runner with the 3.4L V6 removal and installation new panel filter requires two steps. The first is opening the hood and locating the air filter box, This is located on the air hose following the engine's intake manifold. The air filter can be accessed, inspected and then replaced by opening the retaining clips of the box itself. These may be very tight. Before replacing with the new filter element the surfaces and box should be clean of any debris and other dirt. The OE replacement air filter for this application is Denso #1432077.

Which fuse lights the dashboard on a 1995 Toyota 4runner?

Before you change any fuses, try turning the brightness adjustment knob up and down vigorously. Do this at night or in a dark area. This is a common symptom of Toyota vehicles. Also try replacing the headlight switch, this feeds the panel lights. The fuse is rarely the problem. daner@copper.net
