no power to fuel pump

[bigdaddys]

I have no power to the fuel pump I can not find the fuel pump relay 90 camry

[Doctor J]

Have you tried to jump B+ and Fp terminals in the diagniostic connector? With igniition On, 12 V should be present on blue wire at the gas pump

[bigdaddys]

ill try that again is there a relay i was told its on the driver side in front of the strut on fender i can not find it i have air box out an every thing

[bigdaddys]

I do not have any power with the jumper wire what do i need to do is there a relay an if so where

[Dehabur]

You need to reinstall the air box cause that sends the signal to the circuit open relay that is connected to the frame where the engine ECU is in front of the console near the firewall under the carpet. Hope that helps. I found all this information on ALLdata.com for $15.

can anyone tell me where the fuel pump relay is thank you all

[Dehabur]

The circuit openning relay is the fuel pump relay! See above post for location. [ Close Window ] [ Print Window ] Instrument Panel Components.

1. Unplug the Circuit Opening Relay from its location beside the ECU under the center of the dash.
2. Using an Ohmmeter, check for continuity between terminals STA and E1.

Testing Circuit Opening Relay

1. Check that there is continuity between terminals +B and FC. Check that there is NO continuity between terminals +B and FP.
2. If readings are not as specified, replace the Circuit Opening Relay.
3. Apply battery current across terminals STA and E1.
4. Using an Ohmmeter, check that there is continuity between terminals +B and FP.

Testing Circuit Opening Relay Operation

1. Apply battery current across terminals +B and FC.
2. Using a voltmeter, check for 12 volts between terminals FP and FC.
3. If a problem is found, replace the Circuit Opening Relay.

thank you very much ill try this an get back to ya

[Doctor J]

There are 2 relays controlling the fuel pump:
One is EFI relay located in the fuse box near the battery;
Second one is Circuit opening relay located near the engine computer (as mentioned by above posters)
If your CHECK engine light is not on, check the EFI 15A fuse, located next to the relay
and check the ground connector under the driver side head light. If connector is bad the EFI relay will not operate.

I think the pictures above are off top

[bigdaddys]

ok so I messed around with it an i got power to the plug to the pump. I put a jumper in +B an FP an i got power so how do i know if it is the pump bad the pump is not working

[jon-jon]

take a look at my topik , maybe you found something intrensting
http://www.toyotanation.com/forum/sh...95#post3103995

you can test if the blue(+black line) cable at the wellow plug have power
(i dont know if it visible with the deposit intallad)
if yes the the pump is dead , like mine

[bigdaddys]

ok so my pump is bad but why do i only have power to the pump when i put the jumper wire in all the relays are good
