Heres what going on today, I have no power at the fuel pump. Theres a relay behind the ecu pass kick panel, that appears to operate the fuel pump, it has five 5 wires coming to it a blue w/stripe (fuel pump hot) a white wire ( fuel pump ground) center pole from key (power ) what do the other 2 wires do? what operates this relay? With the cover off the relay the set of contact will run the fuel pump , but what make the relay work?? Thanks to all ,I really need some help. Steve

did you ever get a response i have the same problem with a 91 four runner. no power to fuel pump.

also noted in the book is 40 to 60 ohms for 1984 models (60 to 80 for 85-88) the resistance between terminals 3 and 4 should be infinite. on 89 and later there should be continuity between terminals 3 and 4 but none with 2-4, and 3-4, this one is on the driver side kick panel. and this one is called the main relay

now for the pasenger side relay that one is called the circuit opening relay





and for our v6 buddy the same passenger side relay but you have a little more work



check to make sure it is working as the picture shows then you have to apply batter voltage across terminals SAT and E and verify that there is continuity between terminals B and Fp. apply battery voltage across terminals B and Fp and verify that there is continuity between terminals B and Fp.

all pictures and most information on how to do this was taking from the hanes repair manual #92075

Still no luck. Here is the whole deal. The engine was stalling at idle and at acceleration. The Toyota dealer has replace the spark igniter and the coil and plugs. Problem still there. Yesterday I replaced the fuel pump and fuel filter. Getting the tank off and on was a tough job. Anyways, I get no power to the fuel pump now. I jumped a wire directly to the battery and got the fuel pump to work it built up enough gas pressure and the thing started and ran for a minute but as soon as that gas burned it died. This is a 1991 4runner and there are no relays on the passenger side kick panel. On the drivers side kick panel there is a black one and two silver can relays. I don’t know how to test the black one but the silver ones are ok. There is an EFI relay (also silver) on the fender but it checks out ok. Any help you can provide I’d appreciate it.

if it helps this is a four cyl. engine
