If the pump isn't priming then I think you have found the cause of your non-starting issue.
It's still worth checking the spark plug and ditching the fuel for fresh, but also check the connectors and wiring to and from the pump assembly under the tank including the fuel injection relay's terminals (behind the side panel) and its plug for corrosion. You could also check to see if you are getting 12V at the pump connector for five seconds after the ignition is turned on - This will help determine whether the fault lies with the wiring/fuel pump relay or the pump itself.
You can also test the fuel injection relay operation using the in-built diagnostic mode in the dash (where you can also clear old codes). Here is how you do it:
With ignition OFF (and kill switch set to RUN), press and hold SELECT and RESET and then turn the ignition on at the same time time - Keep the buttons held down for at least 8 seconds until everything in the dash display goes blank and 'DIAG' appears. Release the buttons.
You can now use the select button to toggle between 'CO' and 'DIAG' modes. You will need to select 'DIAG' mode. To confirm the selection press and hold SELECT and RESET together again, this time for 2 seconds. Turn the kill switch to OFF after doing this.
Now you need to select the diagnostic code to check the fuel pump test. Use the RESET button to scroll up the list of diagnostic codes and SELECT to scroll down. You need to find '50' and press SELECT and RESET together to select it.
Now you can check/test the fuel injection relay by turning the kill switch to ON. The relay should switch itself on and off five times. You should be able to hear it if its working. Also the FI warning light on the dash should light up each time the relay operates. If you can't hear it, or the light doesn't operate, then there is and issue with the relay, connector or wiring.
Report back with what you find.
FYI - You can also go to diagnostic code 61 to read the error code history (the codes scroll round in the display automatically every 2 seconds) and then to 62 to erase the history (by switching the kill switch off and on again). Diagnostic code 09 will also read/check the actual battery voltage that the ECU is seeing if you want to double check that too.
