When you first turn the key to run position without cranking it you should hear the in tank fuel pump cycle on for x number of seconds and then shut off. There is a schrader valve on the fuel (rail or pipe) system somewhere on the engine. If you remove the cap and touch the valve stem you should get fuel. Use a rag and obviously dont get it in your eyes. It's just a crude test of seeing if any fuel is available.
From there you can install a pressure gauge on the valve and read fuel pressure. You can have good fuel pressure and not volume. At this point you basically want to see something available at the schraeder valve. The car wasn't bumped hard and caused the fuel pump shut off to activate was it?
