when i try to start the vechical i hear the fuel pump running but theres no gas getting into the fuel injectors. i poured gas in the corroborator and it still wont start what could be the problem

You may not have enough pressure in the pump going to the injectors. On the rail you will see a fitting that looks like the one in the photo. You will need to get test gauge and see if you have enough pressure. I think you should be at about 50 PSI... https://www.youtube.com/watch?v=zfOuUzcCo6I
