2007 Sedan suddenly won't start

Is there a simple way to determine if the fuel pump is pumping or not? Someone at work suggested I rent a fuel pressure gauge and connect it to a test port on the car. I'm not sure the Yaris has a test port on the fuel line. My friend said it's similar to the fill or bleed fitting on an A/C system. If it has one, Autozone lends out the meter for free but with a refundable $150 security deposit. I also thought I read somewhere that the Yaris reads the fuel pressure and if it wasn't right that there would be an error code or some other kind of indication? I just hate to spend a lot of time electrially troubleshooting the fuel pump if it may be working. In the old days you could just disconnect a fuel hose and put it in a pail to see if the fuel pump was pumping...

The Yaris does not have an easy place to connect a fuel pressure gauge to. You could just disconnect the quick connect connection to the fuel rail and see if fuel comes out with pressure (do this with the ignition off, so it just releases pressure and does not continue to pump).

The tank is plastic and the pump is suspended in a plastic assembly, so the thump method mentioned above would not have an effect.
