Where is the fuel pump relay on a Toyota Previa?

Toyota Previa Fuel Pump Relay Location
The fuel pump relay in a Toyota Previa is located in the fuse/relay box either under the steering column to the left of the brake pedal or under the hood on the driver’s side in a fuse/relay box. It is also referred to as a circuit opening relay and controls the power to the fuel pump. The circuit opening relay is the second relay from the right in the fuse block under the center fuse box lid, and the underside of the lid will have the relays and fuses identified. Additionally, it’s worth noting that the EFI main relay, which provides power to the circuit opening relay, is located up under the instrument panel behind the combination meter.
If you’re looking for the fuel pump relay in a 2002, 3-liter, 4-wheel drive Previa/Estima, it’s usually the EFI relay in the engine bay fuse box.
In summary, the fuel pump relay in a Toyota Previa can be found in the fuse/relay box under the steering column or under the hood, and it is also known as the circuit opening relay .
I hope this helps! If you have any other questions, feel free to ask.

Where is the EFI relay on a Toyota Previa?

The EFI main relay is up under the instrument panel behind the combination meter.

What relay controls the fuel?

fuel pump relay
The electric fuel pump on a vehicle with a spark ignition engine is controlled by a fuel pump relay. The engine control module (ECM) activates the relay when operating conditions are correct. For safety purposes, the fuel pump relay is only activated when an engine speed signal is received by the ECM.

What does the EFI relay control?

The ECU can control an EFI relay, allowing for management of its own power supply. To achieve this a dedicated Ignition Switch Input and EFI Relay Output are used. When 14V is applied to the Ignition Switch input, the ECU internal circuity switches the EFI relay output On.

Where is the fuel pump relay on a Toyota?

Where is the fuel pump relay switch located?

Find the fuel pump relay in your vehicle’s fuse box.
The main fuse box is usually located underneath the hood near the front of your vehicle, but there may be a smaller fuse box under the steering column inside your vehicle as well.

What happens if your fuel pump relay goes bad?

If the relay fails slowly, then you might notice engine performance symptoms over time. For instance, as the fuel pump relay begins to falter, its ability to power the fuel pump dampens, which can lead to engine stalling when the engine cannot receive enough fuel for combustion.

Will a fuel pump turn on if the relay is bad?

If the relay failed closed (on), the fuel pump will work fine, but it will stay on constantly and eventually drain the battery, at which point you will end up with a no start. If the relay is intermittently working, you may or may not be able to get the engine started and it may or may not stay running.

What happens when a fuel pump relay goes out?
