Question about 1993 Toyota 4Runner

Where's the switch?

We can't seem to find the fuel pump relay switch on my husbands 91 toyota truck! Does it even exist? Or is it called a circuit open relay switch? I've searched all over the internet and can't find any help....can you help us?

    I took apart the panel under the steering column because I thought that it would be under there. I'm not really sure what I was looking for, but was hoping it looked like the ones behind the battery. Kinda big, rectangular, boxed or circular shaped. I was hoping that if it looked like one of those we could narrow it down by taking it in to the autoparts store so they could tell me! =} My husband probably would know what it looked like, but he wasn't home. However, I thought it could possible be under the glove compartment, but nothing on the internet led us to it. We will definitely look under the glove box...after I put back the paneling on the drivers side! =)

Hi,

To my knowledge, there is no separate switch to activate the fuel pump. The fuel pump is one of the many electrical devices powered by the ignition switch when turned on. This is necessary since the fuel pump must be active if and when the engine is running. Due to electrical design, that is to reduce current passing through the ignition switch, a relay is used to along with the ignition switch.

Often, this relay would be among the many relays in the fuse/relay box in the engine compartment pretty close to the battery. However, in your particular model and to my knowledge, it is under the dashboard. More particularly, the fuel pump relay is under and to the right of the glove box above the ECU. There would be two (2) other relays in that area and the fuel pump relay is the last almost hidden.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

if fuel relay is ok ...could be this relay
Circuit Opening Relay
Circuit opening relay controls fuel pump circuit. The Engine Control Module (ECM) receives an input signal at STA terminal when engine is cranking. Starter signal is also applied to terminal STA of circuit opening relay.
Starter signal energizes circuit opening relay during cranking. Circuit opening relay then provides voltage to fuel pump or fuel pump relay.
Fuel pump switch in airflow meter provides ground for circuit opening relay.

Where is the fuel pump fuse and relay located in a 1996 Toyota celica?


7.5 amp ignition fuse, 15 amp EFI fuse-check these- probably under the hood in the fuse/relay block. There is no such fuel pump fuse, the circuit is protected by the above fuses. And the relay is called a Circuit Opening Relay-this is the relay that sends power to the pump when energized.

1992 toyota tercel turns but wont start


running out of ideas, try spray trhotle body cleaner while some one try to start the car, if it runs then your problem is in fuel pump circuit or pump, by pass or jump fuel pump relay and check fuel pressure, check at relay socket your signal from ignition switch it must be hot all times(ignition on) also check your ground points, clean then if excesive resistance, good luck.

1997 Toyota Tacoma 4 WD 4 cyl. Where is the fuel pump relay.


It should be under the driver's dash to the left of the steering column. The Haynes manual recommends you first remove the lower finish panel on that side for access. Haynes calls the fuel pump relay the "circuit opening relay."

there is not a fuel pump reset. but there is a fuel pump relay toyota calls it a circuit opening relay it is behind the right kick panel above the ECM, power comes from the ECM which gets its power from the ECM main relay.

SWITCHES & RELAYS Switches are used in electrical circuits to control the passage of current. The most common use is to open and close circuits between the battery and the various electric devices in the system. Switches are rated according to the amount of amperage they can handle. If a sufficient amperage rated switch is not used in a circuit, the switch could overload and cause damage. Fig. 1: The underhood fuse and relay panel usually contains fuses, relays, flashers and fusible links tcca6p02.jpg
Some electrical components which require a large amount of current to operate use a special switch called a relay. Since these circuits carry a large amount of current, the thickness of the wire in the circuit is also greater. If this large wire were connected from the load to the control switch, the switch would have to carry the high amperage load and the fairing or dash would be twice as large to accommodate the increased size of the wiring harness. To prevent these problems, a relay is used. Relays are composed of a coil and a set of contacts. When the coil has a current passed though it, a magnetic field is formed and this field causes the contacts to move together, completing the circuit. Most relays are normally open, preventing current from passing through the circuit, but they can take any electrical form depending on the job they are intended to do. Relays can be considered "remote control switches." They allow a smaller current to operate devices that require higher amperages. When a small current operates the coil, a larger current is allowed to pass by the contacts. Some common circuits which may use relays are the horn, headlights, starter, electric fuel pump and other high draw circuits. Fig. 2: Relays are composed of a coil and a switch. These two components are linked together so that when one operates, the other operates at the same time. The large wires in the circuit are connected from the battery to one side of the relay switch (B+) and from the opposite side of the relay switch to the load (component). Smaller wires are connected from the relay coil to the control switch for the circuit and from the opposite side of the relay coil to ground tcca6g02.gif
prev.gif next.gif --- I am not aware of an inertia switch on Toyota vehicles. I don't think it's like a ford. Look for a fusible link, fuse, or relay problem.

91 mr2. no power 2 the fuel pump. checked relays and fuses but no power to the fuel pump wires. plz help


When you say you have checked the relays and fuses i hope you checked to see if they have power getting to them. Besides that The most frequent cause of problems is simply a bad contact in wiring connectors. Always check that connections are secure. Inspect the contacts for bent pins or corroded. You may also want to inspect the ground side of the circuit. If everything checks out then you have a bad fuel pump.
