Welcome aboard, sorry for your issues.

You need to loosen the lines at the injectors. After they are loose, pump, crank (with pedal to the floor), pump, crank, charge battery and start over again. Once fuel is coming out of the injector lines hook them up and it should start up. Take a few minutes between cranking with the starter to allow the starter to cool off. You can ruin a starter if you get it too hot.
