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.
Do you
have the same problem?

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.

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.

No I cannot, but when I spray starter fluid in the air filter the car turns over but then shuts off a few seconds later.

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
