Yeah you could just pump it into a bucket. You just need the tool to disconnect the line.

Is there a particular thread that discusses checking for pressure at the pump? In an entirely scientific way (sarcasm intended), I put my ear down to the "Big screw thing" while the engine cranked and didn't hear anything. I don't know how loud they SHOULD be as I've never listened for one on a Yaris before. Betting they are way quieter than my Holley external pump on my Monte Carlo!

The Yaris pump is very noisy, so if you can't hear it from above it isn't running.

Should I perform any further tests or just wait for the fuel pump to arrive from RockAuto?

We were in the shop at home. No external noises, aside from the engine cranking, to cover the noise of the fuel pump. It was not running.

I guess if there is power to the pump while the engine is cranking, and there isn't a hum from the tank, then that seems a pretty strong sign the pump is shot.

I figured if it was something else, I could return the fuel pump.

Before I dunk the new pump in the tank, I can hook it up and see if it comes on.

Anything else I should be checking or doing while I have this open?

Thanks,
Russ

Update:
Went and bought a Lisle - Fuel Tank Lock Ring Tool after figuring the retainer was NOT coming off without something. Followed the instructions on the manual I downloaded from here to replace the pump. With the tool, the entire thing was only about a 1 hour procedure. In the end, the Yaris fired right up and pulled itself out of the shop under it's own power. Success! Now just need to take it out on the road for a test drive.

Thanks to all who helped me.

So can you now hear the fuel pump activating? To be honest, I can't say as I've ever taken note of any fuel pump "sounds" coming from mine. No idea what it should be sounding like. Maybe one day I'll try to listen for it.

Excellent!

Awesome. Glad you were able to fix it yourself too.

Even buying a tool I'd HOPEFULLY only have to use once, I think I came out WAY ahead. $266.78 (RockAuto) for the pump (including expedited shipping) and $42 for the tool (sourced locally). One major chain store had the pump @ $400! Can't IMAGINE what going to a professional shop would have cost.

Now I just need to build my confidence by taking it for a drive.

On a side note, I'm curious as to if the weak pump affected fuel economy. Time will tell.

Yup. I could hear it before I put the seat cushion and metal cover on & the car running. Also, occasionally, it will cycle quickly when I put the key in the "ON" position. Not all the time though. Guessing there is a pressure sensor that lets the pump know if it needs to pressurize the fuel system?

I think the first thing I would check is if it is getting spark at the plugs.
