2007 Toyota Matrix cranks won’t start. Fuel pump good but no power to pump. Circuit opening relay slot is empty in fuse box. Where is fuel pump relay / circuit opening relay on 2007. I can only find 2003. Thanks.

usa car what engine, G16, J20 or h27(v6)
toss coin H27 v6
2 fuse boxes one in engine bay
1 at USA drivers left toe kick panel and up/
"FI" fuse must be good.
relay called double relay runs the fuel pump.

cranks but will not start
the IMMO lamp on dash must not be unhappy per uses guide or fuel is cut dead;. on all cars with IMMO
next scan the PCM for DTC errors.

DTC P0230 FUEL PUMP SUPPLY CIRCUIT MALFUNCTION?


fuel pressure wrong (suspected)

the test is 2 fold. not guessing what is wrong.1
1: out of spec or dead ,fuel pressure at the rail cranking.

2: If that fails voltage at the pump not 11 to 12vdc cranking.

ecu 1 connector below

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.

Check the following:
- Listen to the fuel pump noise under the fuel tank.
- Starter signal.
- EFI relay, under the hood fuse and relay box.
- Fuel pump operation and pressure.
- Regulating valve.
- Circuit Opening Relay (COR) under the dash.
- Check for open in harness and connector between circuit opening relay and fuel pump, and fuel pump and body ground





Hope that works. Thank you for visiting Fixya.

Do you have a test light? If not, go buy a cheap $5 test light-one with a lead to clip to a ground, and with a needle type probe.
Pull the fuel pump relay out of the terminals it is plugged into-you need to check if the power feed for the pump is still available at the relay. Clip the test light lead to a ground and touch the test probe to the positive battery post-to check that your ground is good- tester should light up. Now touch the probe to all of the terminals that the relay plugs into. One terminal should have power with key off. If no terminals have power, you have lost the power feed for the pump. Double check all your maxi fuses in the power distribution box. Either a maxi fuse or a fusible link will be the power feed for the fuel pump relay.
If the power feed is there at the relay, try a new relay. If still no pump, a shop will probably have to check your fuel pump circuit.
Did you check for power at the fuel tank while the key was held in crank? When the engine is cranking, the fuel pump wire should have power. When the key is turned to on, the fuel pump should have power for about 2 seconds, to pressurize the fuel system. Then when key is turned to crank or start, the fuel pump should stay on.

fuel pump relay

check your fuses or the fuel relay which are located in the fuse box either by the drivers side or in the engine compartment,

Are you sure it's running when cranking? It should have come on when key turned on.
This is for camrys up to year '91. It may apply in your '95, also. Check the 7.5 amp ignition fuse and the 15 amp EFI fuse and the EFI main relay, all located in the fuse box next to your battery. There is also the circuit opening relay tied in to fuel pump operation. It is usually found under center of dash. It is usually not the problem, but it is part of the checks for fuel pump operation.
If your car has a " check connector" or "service connector" (also called a fuel pump check connector) under hood on driver's side near the firewall (a little 1 inch cube with a cap on it), then bridge terminals +B and Fp with a jumper wire. Turn key to on (don't start car). The pump should come on. Listen for fuel return noise from the fuel pressure regulator, and verify pressure in hose from the fuel filter. If nothing, check those fuses above. Here is how power runs to pump: Battery to 40 amp main fusible link-to 15 amp EFI fuse-to EFI main relay-to circuit opening relay-to fuel pump-to ground. Ignition switch and the computer (ECU) work the relays to pass power to pump. Hope this helps some, Randy. Good luck.

I think gas is not getting to your fuel rail.

Could be the fuel pump. To access it you will have to remove you rear seat and take off an oval shaped plate. There you can remove it and replace the pump.

1. make sure you really have no fuel delivery. open a line convenient for you as in cold start injector or fuel filter, disconnect ignition coil lead and crank away a bit to make sure you're not getting fuel.
2. I assume you're getting spark.
3. check efi fuse in main relay box passenger side inside right fender. if good check that you have juice at the Co relay hidden in the passenger kick plate. its the white-red terminalwhich delivers the current. the Circuit opening relay is really the main enchilada for getting the pump up and adam.
4. still no go. you have to address the Co relay itself. test terminals with ohm tester. also you can jump wire the Bp fP terminals in the diagnostic connector on the side of the main relay and see if the pump goes.
5. and lastly it might be the pump itself
