I'm trying to help my friend with his GS300. Sometimes it does not start. I'm thinking he may have a problem with his fuel pump relay due to the fact that the problem is intermittant and when it heppened while I was there, I could not hear the fuel pump whine.

Can someone tell me where the fuel pump relay is located and how to access it. A photo would be great.

If someone thinks there is another issue please let me know. He has a P0154 code and P0405 (I think). We replaced one of the O2 sensors a week or so ago and plan to replace the other one soon.

Thanks.

(BTW, I did a search in google and on this section of the forum and could not find any FPR issues).

 

Fuel pump relay is in the engine compartment. Its called Circuit Opening relay

 

Any idea which side of the engine compartment? I seen 3 different panels under there.

Thanks for help.

 

There should be labels under the box

 

Looked under the lid of each box and seen nothing that indicated the Circuit Opening Relay or Fuel Pump Relay. I looked behind the parking brake and seen the fuse panel and a relay on top of it which I could not get out that was large enough to be one. I'm still lost.

 

try the driver's kick panel

 

Still having intermittant starting issues. Usually after a refuel.

I pulled codes yesterday and they are as follows:
P0153, P0154, P0430 and (drum roll please), P2197.

We changed the b2 s1 o2 sensor. I plan to change the B2 S2 sensor today to see what happens after that.
