Where is the fuel pump relay on 1992 Toyota 4 runner


engine bay cluster
the cover has the legend

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


Probably a relay, not a fuse. If there is a fuse it will be marked on the fuse box panel. Usually the relay is located under the hood either in a fuse/relay box or on a rack of several relay on the firewall.

PGM-FI Main Relay

Print
This relay is located behind the dashboard's lower cover. It consists of two individual relays. One is energized whenever the ignition is ON , thus supplying battery voltage to the Powertrain Control Module (PCM). This relay also supplies voltage to the fuel injectors, and power to the second relay. The second relay is energized for two seconds, when the engine is turned ON , to power the fuel pump.
See Figure 1

Fig. Fig. 1: Schematic of the PGM-FI relay
Testing
If the engine starts and continues to run, the PGM-FI relay is working and does not need to be replaced.
See Figure 2

0900c1528008be05.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 2: PGM-FI relay terminal numbers

  1. Remove the relay.
  2. Apply battery voltage to the number three terminal.
  3. Ground the number two terminal.
  4. Check for continuity between terminals five and two.
  5. If continuity is detected, proceed to the step 7.
  6. If there is no continuity, replace the relay.
  7. Connect the number four terminal to the positive side of the battery.
  8. Ground the number two terminal of the relay.
  9. Check for continuity between the number five terminal and the number two terminal of the relay.
  10. If there is continuity, the relay checks out "OK". If the fuel pump still does not work, test the harness.
  11. If there is no continuity, replace the relay and retest.

Car will turn over but won't start. Through the


No noise from fuel pump when you turn over the car .First thing get voltage at fuel pump relay checked, is there 12 volt to the relay.If no, then problem is again the relay.--------- To reconfirm the problem, try other test, that is remove the relay and by pass the relay terminals with a jumper wire .Then with 12 volt external battery give power to fuel pump connector and see, if the fuel pump starts, then its clear that fuel pump relay is faulty.----------- Also other problem can be fuel pump inertia switch.If the inertia switch is faulty then also fuel pump will not start.-------- The fuel pump relay on a 1995 Ford Explorer is in the power distribution
box, in the engine compartment, driver's side near the firewall.----------
The fuel pump inertia switch is in the right front passenger area
it is below the dash but above the carpet in the right hand corner.--------
Its a push button type inertia switch.
--------
Fuel Pump Activation
When ignition switch is turned to START position, PCM operates fuel pump relay to provide fuel for starting engine. PCM senses engine speed and shuts off fuel pump by opening ground circuit to fuel pump relay when engine stops or engine speed drops to less than 120 RPM. When ignition switch is in ON position, EEC power relay is energized (contacts closed). Power is provided to fuel pump relay and timer in PCM. Fuel pump receives power through fuel pump relay contacts.
Inertia Fuel Shutoff (IFS) Switch
All models use an electrical interrupt switch in fuel system. During a collision or vehicle rollover, electrical contacts within inertia switch open, shutting off fuel supply to electric fuel pump. Fuel supply is interrupted even when engine is running.
A reset button is located on switch assembly. If electrical circuit trips, vehicle will not restart until switch is reset. Fuel system should be inspected before resetting switch.
IFS switch is located under instrument panel, near right side of transmission hump.
----------- If the fuel pump relay, the inertia switch and fuel pump all checked ok, and fuel pump is working with direct 12 volt source to fuel pump.Then problem relates to computer.The computer (power control module, PCM) is faulty and has to be replaced.--------- This will help.Thanks.Helpmech.

Both fuel pump relays run hot. I have replaced both of them. The truck started and ran for about 30 minutes then quit. I replaced the relays and it ran for a few minutes and quit again.


You could have a bad fuel pump relay switch. The fuel pumpmag-glass_10x10.gif relay switch gets the fuel pump running in the vehicle during the start cycle. The terms fuel pump relay and fuel pump relay switch are used interchangeably. The fuel pump relay begins its job when the automobile operator turns to the ignition on, but before the motor is actually running. At that point, the fuel pump relay in some cars sends a signal to the ignition switch, which in turn sends a signal to the fuel pump to turn on. Others fuel pump relays have actual circuitry inside of them that receive the ignition signal and directly signal the fuel pump to engage.

Have a great day!

FUEL PUMP FOR CHEVY SILVERADO


fuel filter? how about power to the fuel pump,loose ground wire to chasis? wiring harness? terminals clean at point of connection?did you check the fuel pump relay? Relay is located in electrical center under the hood on the driver side.relay and fuse legend will be on bottom side of cover, you sould be able to switch with another relay that you know works, ie: switch horn relay with fuel pump relay, honk horn to insure both relays are working when either relay is inserted into horn slot. Do you by chance have the electrical schematic drawing for the fuel pump?
