Hello.

The circuit opening relay controls fuel pump circuit. When EFI main relay is energized, EFI main relay provides battery voltage to one side of circuit opening relay. Inspect this relay for fuel pump diagnosis. It is located at top corner of relay box, behind driver's side kick panel.

Thanks for using 2CarPros. Com!

Thanks very much, Bluelightnin6, for your prompt help.
I found the relay barely hanging there - had come partially unplugged due to heavy banging on the door pillar.
Once I pressed it in, the car started.

Great forum!

Where is the fuel pump relay on an 05 Avalon Limited? If it's in the engine bay fuse/relay box, specifically WHICH relay is it? What color is the power wire(s) that are only hot when the engine is turning? Thanks!

I stopped for gas turned my car off then went to leave and my car would not turn over. I sprayed starter fluid in the air box and it turned right over. So wondering if it's the pump or is it the relay? I cannot find where the relay is located. Should the new relay be an exact match for the replacement? I bought one at AutoZone and I cannot find any relay that matches the size of the new one.

Good afternoon,

I doubt it is the relay at all. It is in the under dash fuse block. I attached a picture for you to view. Yes, you need the exact relay not generic. I would get one from Toyota. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Okay, that's where I had thought it was and yea the replacement does not match up to that relay. It's a q/3 smaller in size. So in your opinion does it sound like the fuel pump is bad? I really cannot hear it engage when I set key to aux mode.

You need to check the pump for pressure. Can you hear it run with the key turned on? Not the accessory position, the on position.

As far as the relay, you need the correct relay.

You can rent a tester at a parts store to check the pressure.

Can you hear the pump run when the key is turned on?

No I cannot hear it at all. Is the fuel pump located above the gas tank?

Okay, the fuel pump is in the fuel tank but you can get to it from the top.

I attached a diagram. You need to check for voltage on the blue wire to the pump when you turn the key on
