What happens if a Toyota RAV4 fuel pump goes bad?
One of the worst problems that can happen to a vehicle is a bad fuel pump . If your Toyota Rav4’s fuel pump goes bad, no fuel (or not enough fuel depending on whether or not it’s out all the way) can enter the engine. Without gas your Rav4 will not run at all.
What to do if your fuel pump doesn’t work?
Thought it was a bad pump so dropped the tank and replaced it..still didn’t work so checked for power at the connector under the rear seat.. nothing.. Swapped out the EFI relay and EFI fuse with working ones still nothing. Jumped the e1 and t terminals in the diagnosis box to check for check engine codes and its showing normal, no problems.
Why is there no fuel in the tank?
I replaced the fuel pump, fuel filter, and tank selector switch, but still no fuel. Other possible causes of your lack of fuel issue could be the fuel injectors or an electrical problem. If the fuel injector fuse (s) are blown due to a wiring issue, this may cause your problem.
Where is the fuel pump relay on a Toyota?
The relay you are talking about is called the “Circuit Opening Relay” and is located on top of the ECU, which is between the driver and passenger footwell behind the radio. You can get to it by pulling back the front inner corner of the passenger carpet.
Where is the open circuit relay on a Toyota RAV4?
The open circuit relay is in the kick panel, drivers side. I thought you said it powered up but didn’t pump fuel? There are two boxes with fuses and relays under the hood. One above the fuel filter and one by the driver side headlight. The relay block by the kick panel is the another. Are all other lights and electrical switches working?
Where are the fuses on a Toyota RAV4?
Click on Merged_Rav4_User_Manual.pdf , then go to page 222. There are diagrams indicating the correct position of the fuses. As Ken proposed, you have to look for fuse No 8 (EFI 20 A (U.S.A.) or 15 A (Canada): Multiport fuel injection system/sequential multiport fuel injection system).
What are the symptoms of a bad fuel pump?
Here are the most common symptoms of a bad fuel pump in your Toyota Rav4: One of the most common signs that a fuel pump is going bad is a whining sound. The whining sound can indicate that the fuel pump is going out before there are any performance based issues.
What to do if your fuel pump has no power?
Found the relays and swapped the EFI relay with the ACC relay and power relay, no power to pump. Swapped the circuit opening relay and no power. Checked all the fuses and all good. Disconnected the fuel line and ran power directly to the pump and it came on but no fuel moved.
What are the relays on a Toyota RAV4?
There are four relays there, one of them is the EFI relay, which one I don’t know but three are the same so start by swapping these about. Good luck. Thanks Ken!!! Found the relays and swapped the EFI relay with the ACC relay and power relay, no power to pump. Swapped the circuit opening relay and no power. Checked all the fuses and all good.
Why is the fuel pump and relay not working?
The ignition circuit, which includes the ignition switch, controls power to many components, including the fuel pump and relay. If there is an issue with the switch or the circuit, perhaps a wiring problem, then power to the fuel system may be cut off.
Why does my Toyota RAV4 engine not start?
There are a lot of issues that can cause your Rav4 to crank, but not start. The engine needs air, fuel, and a spark in order to run. It is highly likely that if the engine is cranking, but not starting that it has thrown an OBDII code. It is definitely worth it to use an OBDII scanner to check and see if the engine has thrown any trouble codes.
What should the voltage be on a Toyota RAV4?
The voltage of the battery on your Toyota RAV4 can be measured precisely with a multimeter. Before the test, the multimeter is set to the voltage range of the battery and connected to its plus and minus poles. Successful testing of the car battery, i.e. checking the voltage, usually results in values of approx. 12 to 13 volts.
Why does my Toyota Rav 4 have no power?
Fuel blockage. Toyota RAV 42.0 D Engines are fitted with a Denso electronic high-pressure fuel pump. Controlling, the fuel rail pressure and the volume of fuel and are both replaceable items. Denso also make the Fuel Pressure Regulator (we call it the SCV) that can cause the lack of power problems with the Toyota RAV4 Problems.
What to do if your fuel pump is not working?
If nothing after that, then the fuel pressure regulator is not working and needs replacing. If you get pressure to the rail, then there could be a problem with the injectors; they may be either dirty or plugged up. Take the injectors off the engine and clean them with CLR.
What should the PSI be on the fuel pump?
With the engine off and key on, there should be 45 to 60 PSI on the gauge. If there is nothing on the gauge, then check your connection to the shrader valve. You may need to remove the shrader part of the valve from the threaded tube. If there is still no pressure, then replace the fuel filter and retest.
Where is the EFI relay on a 1998 RAV4?
The main EFI relay for the 1998 RAV4 is on the back of the fuse block in the vehicle and have swapped out the relays I told you about, power and ACC (accessory). I have replaced the 20 amp fuse in relay/fuse box. I guess Ill replace the 2 relays and see what happens. So what happened? I am also curios what happened?
Where does the fuel pump go in a car?
In modern fuel injected vehicles, the fuel pump sits right in the fuel tank and “pushes” the gasoline to the fuel rail (s). It is in the fuel tank because “pushing” fuel to the fuel rail is easier than “pulling” the fuel, which is what an inline pump would do.
